Before answering the question i.e. which screw sizes are required for an lg tv wall mount, it is important to know that what is a VESA mounting pattern. The back panel of your LG television contains either 4 or 6 pre-drilled holes arranged in a square or rectangular shape. This standard hole pattern is referred to as the VESA mounting interface. VESA stands for the Video Electronics Standards Association, which created this standardized screw configuration to accommodate TV wall mounting brackets.

The important measurements are the horizontal and vertical distances between the holes, stated in millimeters. For example, a common VESA measurement is 400mm x 400mm. This means the holes are spaced 400mm apart left-to-right and 400mm apart top-to-bottom.

Common VESA measurements for LG TVs are:

  • 75 x 75 mm
  • 100 x 100 mm
  • 200 x 200 mm
  • 300 x 300 mm
  • 400 x 400 mm
  • 600 x 400 mm

LG helpfully labels their TVs on the back panel with the specific VESA size. You can also easily measure the hole spacing yourself if it is not marked.

Knowing your exact VESA pattern is key for choosing a wall mount bracket that is compatible. The bracket must align precisely with the holes on your TV to be installed securely.

Pre-Drilling Essential Pilot Holes

Before ever driving any screws into your carefully marked stud or anchor points, take the vital step of pre-drilling guide holes for each screw approximately 1/2” deeper than the screw length. Using a power drill with the appropriate sized drill bit, pre-drilling prevents cracking, splintering and screw seizing during installation.

For softwood studs, use a 3/32” drill bit for the smaller M4 or M5 screws and a slightly larger 7/32” drill bit for M6 or M8 screws. For concrete or brick, use a 5/16” masonry drill bit. Allowing screws to slide smoothly into pre-drilled pilot holes is the best way to prevent stripping, snapping or weakening of the base material.

Washers Add Extra Installation Security

For enhanced pull-out protection against a heavy LG TV shifting or gradually working loose over time, consider using flat washers in combination with your mounting screws.

Washers help distribute shear and tension forces over a wider surface area for improved resistance to loosening. Simply place a washer under each screw head and another washer between the mount plate and TV back panel.

This braces and sandwiches the VESA mounting points to minimize slippage or rotation under load. While not mandatory, washers provide inexpensive insurance against vibrations or sudden impacts pulling screws loose, especially on extra large TV installs.

Carefully Tightening and Checking Screw Connections

With pre-drilled holes and your selected screws and washers in hand, carefully follow the detailed installation instructions included with both your wall bracket and LG TV. Tighten screws incrementally in an “X” pattern to evenly draw the TV back flush against the wall plate.

Use a low-torque, variable speed drill/driver to avoid over-tightening screws. Gradually tighten until snug, evenly engaging the mount without crushing the panel. Visually check around the panel perimeter for any gaps indicating uneven tightening.

Finally, firmly but gently pull or twist on the upper corners of the mounted TV to confirm no slippage or movement. Periodically check connections over time and retighten any loose screws as needed. Proper care while tightening and verifying screw installation results in secure TV mounting enjoyment for years to come.

Frequently Asked Questions about Selecting Screw Sizes
