Purpose and audience

These self-tapping screws secure electrical boxes, brackets and plates to metal studs. They are intended for installers and electricians who need a reliable fastener for 4-11/16 in boxes in commercial or residential projects.

Compatibility check

Verify that the mounting surface is a metal stud and that the box depth matches the 4-11/16 in specification. Confirm that a .5 in screw length provides sufficient engagement for the material thickness in your application.

Build integration

The wafer-head design sits flush to keep cover plates flat and avoid interference with devices. Each pack supplies 100 pieces so a single box can handle multiple rough-in locations without reordering. Steel construction resists stripping during drive-in.

Questions about this item

What comes in the box and what extra items are needed to use the SMS8 self-tapping screws?

The box contains 100 silver steel self-tapping screws, each 0.5 in long with a thin wafer head. No additional hardware is included; you only need a suitable driver bit and the metal studs or 4-11/16 in boxes you are mounting.

Which pack size should I choose for mounting brackets to metal studs?

The only option listed is the 100-piece pack. That quantity covers multiple 4 in mounting points on 4-11/16 in boxes, so one pack is usually enough for a typical residential or light-commercial job.

How does the 0.5 in length perform when fastening into metal studs?

At 0.5 in long, the screw engages the thin gauge of a metal stud without protruding through the far side, giving a secure hold for brackets and plates while keeping the wafer head flush with the accessory surface.
