Metallics JFWPB24 8 x 3 in. Flat Head Phillips Wood Screws - Brass - Each

The JFWPB24 ships as a jar of 100 screws, and 100 is the order minimum, so a jar is the smallest buy. The jar weighs 1.34 lbs. Metallics lists other sizes and quantities in the JFWPB series by request.

A #2 Phillips bit. The recess is a Phillips drive with a 0.191 to 0.204 in. recess diameter, 0.113 to 0.136 in. depth and 0.032 in. slot width, which is standard #2 geometry. Brass is soft, so keep the bit seated and run slow to avoid stripping the recess.

No. The JFWPB24 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your project has domestic-sourcing requirements, these screws will not clear them.

Metallics specs the JFWPB thread run as 2/3 of the length on anything over 1 inch, so a 3 inch screw carries roughly 2 inches of thread at 15 threads per inch with an unthreaded shank below the head. That shank is what lets the top board pull tight against the bottom one, so size your clearance hole in the top piece to the shank, not the thread.

Brass is the reason to pick the JFWPB24. It does not rust, so it holds up in damp and exterior work and in cedar or redwood where plain steel stains the wood. The trade-off is strength: brass is softer than steel, so pre-drill a pilot hole and drive it by hand or on low torque. For structural framing loads, use a steel or coated structural screw instead.

They are built to ASME B18.6.1, with the thread conforming to ASME B18.6.1-1997. That covers head and recess dimensions, so the 0.292 to 0.332 in. head width and #2 Phillips recess are to standard rather than proprietary.

Metallics puts the JFWPB series into electrical, plumbing, heating and air conditioning work. At 3 inches a #8 is long enough to mount strut, boxes, backer blocks and straps through finish material into studs or blocking, and the brass body keeps it from rusting where the device or fitting is brass or exposed to moisture.
