Screws For Samsung TV Mount | Size And Length Guide

Most Samsung TV mounts use M4, M6, or M8 VESA screws sized by screen, pattern, and bracket thickness.

Lost the bolts that came with your Samsung wall bracket, or bought a third party mount that shipped without hardware? Getting the right screws for a Samsung TV mount matters for safety, picture height, and warranty, yet the labels on the box often feel vague.

This guide breaks down Samsung TV wall mount screws in clear terms. You will see which screw thread your TV needs, how length changes with bracket depth and spacers, and a simple way to double check everything before you hang the screen.

Screws For Samsung TV Mount: Core Specs

Samsung follows the VESA mounting standard on current flat screen TVs, so the screws that hold the brackets to the back of the TV use metric machine threads, not wood screws. Samsung guidance for wall mount hardware lists three screw diameters for the TV side: M4, M6, and M8, picked based on screen size.

Samsung wall mounting help pages describe a simple rule of thumb by size:

Pick M4 screws for small Samsung TVs around 19 to 22 inches.
Pick M6 screws for mid sized screens around 30 to 40 inches.
Pick M8 screws for larger Samsung TVs from the low forties up to big 80 inch models.

Thread pitch on these VESA bolts stays the same. Samsung lists a pitch of 1.25 millimetres for all three screw diameters, so a correct screw spec looks like M8 x 1.25 or M6 x 1.25. The second number you see on a screw box, such as 45 mm, describes length, not pitch.

One more detail often buried in manuals is that the mount bracket adds thickness. Bracket steel, plastic spacers, and washers all eat up length on the screw before it reaches the threaded inserts in the TV. That is why you should match both screw diameter and length, not diameter alone.

Check Your Samsung TV VESA Pattern And Size

Before you buy hardware, you want two basic numbers from the back of the TV: the VESA pattern and the screen size. Samsung lists both right on the spec sheet, and you can also measure the VESA pattern yourself with a tape measure.

Find The VESA Mount Pattern

On the back of your Samsung TV you will see four threaded mounting holes. The VESA pattern is the distance between those holes in millimetres, measured horizontally and vertically. Common patterns for Samsung TVs are 100 x 100, 200 x 200, 400 x 400, and 600 x 400.

Brands that design wall brackets around the VESA standard, such as Ergotron, explain this pattern in simple form as “horizontal distance x vertical distance” between the four holes on the TV case.

Match VESA Pattern To Screen Size

Samsung guidance on wall mounting links VESA patterns to screen size ranges in a Samsung wall mounting guide. That table gives a useful shortcut when you cannot reach the back of the TV yet:

Approximate Samsung TV Size	Typical VESA Pattern	Common Screw Diameter
19–22 inch	100 x 100 mm	M4
23–29 inch	200 x 100 mm	M4 or M6
30–43 inch	200 x 200 mm	M6
46–75 inch	400 x 400 mm	M8
75 inch and larger	600 x 400 mm	M8

This table lines up with Samsung notes that list M4 for small sets, M6 for mid sized screens, and M8 for larger models from the low forties upward. The exact combination for your TV can still vary, so use the model number and manual as your final check.

Typical Screw Sizes For Common Samsung TV Mounts

Once you know the VESA pattern and rough screen size, you can pick screws for Samsung TV mount brackets with far more confidence. The notes below assume you are buying the bolts yourself, instead of using the hardware that ships with a Samsung branded wall mount.

Small Samsung TVs (Around 19–22 Inches)

Small bedrooms, kitchens, and office corners often use compact Samsung TVs under 24 inches. These panels sit on lighter brackets and need thinner screws.

Use M4 screws into the TV side mounting holes for most 19–22 inch Samsung TVs.
Start with 10–12 mm screw length inside the TV case, then add bracket and spacer thickness on top.
Check for shallow inserts by threading a bare screw gently by hand; if you feel a hard stop early, pick a shorter bolt.

Shorter screws on these sets protect the thin back panel. If the screw reaches too far, it can crack the housing or push against the LCD or OLED layer.

Mid Range Samsung TVs (Around 30–43 Inches)

Living rooms and gaming setups often sit in this middle band, where Samsung spec sheets list M6 screws and VESA patterns such as 200 x 200 or 300 x 300 on some models.

Use M6 screws in the TV mount holes for screens in the 30–40 inch range.
Plan on 12–20 mm of thread inside the TV, then add the full thickness of the bracket plate and spacers.
Stay with 1.25 mm pitch so the bolts match the inserts on the TV chassis.

Many universal wall mount kits include both M6 and M8 hardware. Check the label and trays carefully before you buy, so you do not end up missing half the set once the TV is already off the stand.

Large Samsung TVs (43–88 Inches)

Most Samsung QLED, OLED, and big Crystal UHD TVs from the mid forties up through 80 inches use M8 bolts on the back of the set. Screen weight climbs fast in this range, so you want a sturdy bracket, proper wall anchors, and bolts that match both.

Use M8 screws for large Samsung TVs with VESA 400 x 400, 600 x 400, or similar patterns.
Expect 20–25 mm of thread inside the TV as a common range listed in manuals for 55–70 inch sets.
Add bracket and spacer depth on top of that thread length, then round up to the next 5 mm screw length that your hardware store carries.

Samsung wall mounting guides suggest that bolt length changes with bracket style and spacer height. Universal M8 screw kits for Samsung TVs pack several bolt lengths plus clear plastic spacers, which gives room to fine tune the fit on thick or curved back panels.

How To Measure Correct Screw Length For Your Samsung TV

Diameter and thread pitch are easy once you have screen size and VESA pattern. Length takes a little more thought, since the screw has to pass through the bracket and any spacers before it bites into the TV case.

Measure Thread Depth In The TV

You can estimate thread depth with simple tools at home. Take a cocktail stick or thin plastic zip tie and gently slide it into one mounting hole until it reaches the bottom. Mark that point with a pen at the surface of the back panel, then measure the distance with a ruler.

Write down the depth you measured in millimetres for at least two of the four mounting holes.
Subtract two to three millimetres as a safety margin so the screw never presses into the inside of the panel.
Use that number as “C” in the common length formula Samsung shares for wall mount screws.

Add Bracket, Spacers, And Washers

Next you add the thickness of parts that sit between the bolt head and the TV case. Samsung diagrams break this into three pieces: C for the thread inside the TV, X for bracket thickness, and Z for spacer or washer thickness.

Measure the steel plate of your bracket near one mounting slot to get X.
Stack any spacers or washers you plan to use and measure that pile to get Z.
Add C + X + Z together, then round up to the nearest standard bolt length such as 25, 30, 35, or 45 mm.

Screws for Samsung TV mount brackets are usually sold in 5 mm steps, so that rounding step matters. If your maths says 28 mm, a 30 mm screw with a flat washer gives a safe fit while still leaving enough thread engaged inside the inserts.

Test Fit By Hand Before You Hang The TV

Once you have the screws, always test fit them by hand before you lift the TV onto the wall plate.

Thread each bolt slowly into the TV holes without the bracket first and stop the moment you feel resistance.
Back the screw out again and check how much thread was engaged; you should see clean marks along the thread, not gouges.
Add the bracket and spacers, then repeat the hand test, making sure you still feel a firm stop before the screw head presses hard into the bracket.

If a screw never seems to tighten, you may have picked a bolt that is too short or cross threaded. Stop, check the thread carefully, and move to a fresh hole instead of forcing it.

Buying Screws And Hardware Kits For Samsung TV Mounts

Once you know you need M4, M6, or M8 bolts with a 1.25 mm pitch, you can either order a Samsung specific kit or use a universal set that lists Samsung compatibility on the box.

Use Hardware That Ships With A VESA Wall Mount

Many fixed, tilt, and full motion brackets list Samsung in their compatibility section and ship with an assortment of bolts, washers, and spacers. When that kit matches the VESA pattern and weight of your TV, it is usually the easiest path since the lengths are picked with flat and curved Samsung backs in mind.

Check the parts diagram in the bracket manual to see which screws the maker suggests for Samsung TVs.
Lay out the screw bags on a table and label them by size before you start, so you always know which bolts you are grabbing.
Keep spare spacers nearby in case you need to shift the TV away from the wall to clear HDMI, antenna, or power plugs.

Samsung’s own wall mounting pages point out that branded wall mounts come with all the screws, spacers, and washers you need. That includes the correct length M4, M6, or M8 bolts for the TV side along with lag bolts or anchors for the wall side.

Buy A Universal Samsung Screw Kit

If your mount is second hand or the original hardware has gone missing, a dedicated screw set for Samsung TV mounts can save a trip back to the store. These kits usually come with four M8 bolts in several lengths plus spacers sized for common Samsung backs.

Look for “fits Samsung TVs” and mention of M8 x 1.25 on the package.
Pick a kit with several bolt lengths so you can handle thin and thick bracket plates without strain on the threads.
Keep the leftover screws in a labelled bag taped inside the TV cabinet for later height changes or bracket swaps.

Some kits also include M4 and M6 bolts for smaller Samsung sets. Keep those sizes separate from generic wood screws in your toolbox so they do not walk off to other projects.

Buy Individual Screws At A Hardware Store

If you prefer to buy only what you need, you can pick up individual bolts at a decent hardware counter. Take a reference screw if you have one, or write down M4, M6, or M8 with a pitch of 1.25 mm and your calculated length.

Ask for metric machine screws, not sheet metal or wood screws, since the threads are different.
Grab matching flat washers so the bolt head does not bite into the bracket slots.
Buy one extra bolt per size as cheap insurance in case one head rounds off or drops inside a wall cavity.

Bring the TV manual or a photo of the rating label if you feel unsure at the counter. The label often lists the VESA pattern and screw size in tiny print near the serial number.

Safety Tips When Mounting A Samsung TV With New Screws

Screws for Samsung TV mounts are only one part of a safe wall setup. You also need a solid wall, proper anchors, and at least one other person to help lift and hang the screen.

Check Wall Type And Studs

Mount instructions from Samsung stress that the bracket must sit on a wall that can carry the weight of the TV plus the mount, and that lag bolts should grab solid studs or masonry where possible.

Use a stud finder to locate wood studs in drywall and mark their centres with a pencil.
Pre drill pilot holes for lag bolts so the studs do not split while you tighten them.
Use anchors rated for the load if you have to mount on brick, block, or concrete.

Never use the small M4, M6, or M8 VESA screws alone to hold the TV on the wall. They only attach the bracket to the TV; the large lag bolts or anchors into the wall carry the weight.

Check Torque And Alignment

Once the screws for the Samsung TV mount are in place, spend a few minutes on final checks before you run cables and move furniture back.

Look for an even gap between the TV and wall across the top edge so you know the bracket is not twisted.
Confirm every screw feels snug by giving each one a short final turn with the correct screwdriver or socket.
Test tilt and swivel on an articulating arm by moving the screen through its range and watching for flex or creaks.

Step back, check that the TV sits level, and then route cables so nothing tugs on the connectors when you move the screen later.

Quick Reference: Picking Screws For A Samsung TV Mount

Choosing screws for a Samsung TV mount comes down to a few clear checks. Once you know your screen size, VESA pattern, and bracket style, the matching bolts fall into place without guesswork.

Confirm M4, M6, or M8 size from the Samsung manual, rating label, or wall mounting guide.
Measure thread depth inside the TV case, then add bracket and spacer thickness to set bolt length.
Check for 1.25 mm pitch on metric bolts so they match the threaded inserts on the TV.
Test fit by hand before you lift the TV onto the mount, and stop if a screw binds or spins freely.

Once the right screws are in place and the bracket sits on solid anchors, your Samsung TV should hang securely with clean cable runs and a tidy look on the wall.
