Metallics JRBWS10 Screw 8 x 1/2 RH SL WS BR (Jar 100)

Each jar holds 100 of the #8 x 1/2 inch brass round head wood screws. The packaging is a jar rather than a box or bag, which is the usual format for small-count electrical trim fasteners kept on a service truck or bench.

That's the intended use. The JRBWS10 is carried as an electrical fastener, and a 1/2 inch #8 round head wood screw is a trim-length screw: it bites into wood or a wood backing board rather than sheet metal, and the round head seats on the surface instead of countersinking. At only 1/2 inch of length it is not a structural fastener, so use it for plates, straps, small boxes and brackets fixed to wood.

The JRBWS10 is a slotted (SL) screw only, so it takes a flat blade. There is no Phillips or square recess on it. If your crews are set up on Phillips or Torx bits, plan on a flat tip in the kit, or pick a Phillips-drive #8 wood screw instead. Slotted brass is common on switch plates and traditional trim where the look of the slot matters.

Brass is the finish-and-corrosion choice. The JRBWS10 is brass rather than plated steel, so it holds its color against polished brass or bronze cover plates and won't rust-stain in damp or coastal interiors. The trade-off is that brass is softer than steel, so drive it with a hand driver in a pilot hole rather than running it down with an impact driver, or you'll twist heads off.

For a property manager swapping trim screws, a 100-count jar of #8 x 1/2 inch brass round head screws covers roughly 50 duplex or switch plates at two screws each, so count your openings before ordering a single jar. Buying the same JRBWS10 for every plate keeps the drive type and head profile consistent, which is what makes a hallway of devices look like one job rather than three.
