Metallics JRBWS14 Screw 8 x 1 RH SL WS BR (Jar 100)

It's a #8 x 1 inch wood screw with a round head and a slotted drive, in brass. The abbreviations on the Metallics part code read RH for round head, SL for slotted, WS for wood screw and BR for brass. Order code is JRBWS14.

100 screws per jar, and the jar is the pack the part ships in, so the quantity is fixed at 100 per unit rather than sold loose by the piece.

A #8 x 1 inch wood screw is cut for wood, so it holds in a stud, a wood blocking piece or a wood backbox. One inch of total length means roughly half the shank is in the stud once you pass through 1/2 inch drywall, which is fine for light devices and plates but not for anything carrying load. For drywall only, use an anchor instead.

Yes for wood. The round head seats on the surface and leaves a finished brass dome, which is what you want on a visible wood panel or trim piece. It does not sit flush, so if the plate is countersunk or has to be flat under something else, you want a flat head instead of this round head.

Brass doesn't rust-stain, so it's the usual pick where the screw head stays visible, on finish plates, wood cover panels, decorative escutcheons and similar. The tradeoff is that brass is softer than steel, so a slotted brass head cams out and burrs more easily. Drive it with a correctly sized flat blade, not a power driver at speed, and pre-drill hardwood.
