Metallics JFWP44SS 12 x 3 in. Flat Head Phillips Wood Screws - 18-8 Stainless - Each

Use a #3 Phillips bit. The recess is 0.270 to 0.283 inch in diameter and 0.148 to 0.171 inch deep, so a #2 bit will bottom out and cam out on a 3 inch screw being driven into solid wood. Keep a few #3 bits on the truck if you are running a full jar.

18-8 stainless is the material, which is the standard austenitic grade used for general exterior and damp-location fastening, and the screws are supplied without any additional plating or coating, so there is no finish to wear off and start rusting. Metallics lists the field application as electrical, plumbing, heating and air conditioning work.

No. These screws are listed as not Buy American compliant and not ARRA compliant, with country of origin shown as multiple. For a job with domestic sourcing requirements you will need a fastener line certified as domestic.

They ship 100 to a jar, and the jar is the order minimum. Jar weight is 2.4 lbs. If you need a different count or a different size in the same JFWP flat head stainless family, other sizes and quantities are available by request.

On the JFWP flat head wood screws, thread length runs two thirds of the overall length once length exceeds 1 inch, so a 3 inch screw carries roughly 2 inches of thread with an unthreaded shank under the head. That shank is what lets the screw clamp a strap, bracket or board tight to the framing instead of jacking it off the surface.

These are #12 x 3 in. tapered point wood screws made to the ASME B18.6.1-1997 thread standard, which is a general purpose wood screw spec, not a structural one. They are the right pick for anchoring straps, boxes, backer boards and equipment to wood where corrosion resistance matters. For rated structural connections, framing or joist hangers, use a fastener with a published structural load rating instead.
