Metallics JFWP43SS 12 x 2-1/2 in. Flat Head Phillips Wood Screws - 18-8 Stainless - Each

A #3 Phillips driver. The recess on these #12 screws runs 0.270 to 0.283 inch in diameter and 0.148 to 0.171 inch deep, so a #2 bit will sit shallow and cam out under torque. Keep a #3 in the pouch for the whole box.

18-8 stainless is the standard austenitic grade used where plain or zinc plated screws would rust, so it holds up in exterior trim, damp crawl spaces, and mechanical rooms. The screws are supplied bare with no additional finish, which is normal for stainless. For direct saltwater exposure or chronic chloride contact, 316 is the grade to specify instead.

Pre-drilling is the safer habit with these. They are tapered point screws at 11 threads per inch in a #12 diameter, and stainless is softer than hardened steel, so driving dry into oak, maple, or near an edge risks snapping the shank. A pilot hole sized to the root diameter in hardwood, plus a clearance hole through the top piece, keeps the heads seating instead of twisting off.

No. These are flagged not Buy American compliant and not ARRA compliant, with country of origin listed as multiple. On a federally funded job with domestic sourcing requirements, you will need a domestically produced fastener instead.

They are built to ASME B18.6.1, with threads to ASME B18.6.1-1997. If a drawing or spec calls out B18.6.1 flat head Phillips wood screws, the JFWP43SS answers it on head geometry, recess, and thread form.

They come in a jar of 100, which is the order minimum. Handy for a service truck or a shop drawer rather than a bulk box, and the full jar weighs 1.74 lbs.

No. The diameter designation matches, but the JFWP43SS is a tapered point wood screw at 11 threads per inch with a coarse, deeper thread and a partially unthreaded shank, made to cut and hold in wood fiber. Sheet metal and self-drilling screws are fully threaded with a different pitch and point and are the right call for steel studs or sheet stock. For wood, blocking, and plywood, use this one.
