Metallics JFWP44 12 x 3 in. Flat Head Phillips Wood Screws - Steel Zinc - Each

A #3 Phillips bit. The JFWP44 is a Phillips drive screw and the recess is sized for a #3 driver, with a recess diameter of 0.270 to 0.283 in. and a depth of 0.148 to 0.171 in. A #2 bit will sit shallow in that recess and cam out under torque on a 3 inch screw, so keep #3 bits on the cart before the crew starts.

No. The JFWP44 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If you are working a federally funded project with domestic sourcing requirements, this screw will not satisfy the submittal and you need a domestically produced fastener instead.

The JFWP44 runs 3 inches long with 11 threads per inch and a tapered point. Thread length follows the wood screw convention of roughly two thirds of the overall length, so you get about 2 inches of thread and an unthreaded shank up near the head. That shank is what lets the screw draw a top board tight to the one underneath, as long as your pilot hole in the top piece is clearance sized rather than threaded.

The JFWP44 is steel with a zinc finish, which is a dry indoor plating. It handles general interior work, mechanical rooms, and framing fine, but zinc plating is not a marine or pressure treated lumber coating. For decks, treated lumber, or anything exposed to weather, go with a stainless or an exterior coated wood screw instead.

Yes. The JFWP44 is built to ASME B18.6.1 for dimensions, with the thread conforming to ASME B18.6.1-1997. That means head diameter, head height, thread pitch, and point geometry fall in the published tolerance bands for a #12 flat head Phillips wood screw, so it will interchange with any other screw called out to that standard on a drawing or submittal.

The JFWP44 ships in a jar of 100 pieces, and 100 is the order minimum. The filled jar weighs 2.07 lbs. If you need a different count or a different size in the JFWP series, Metallics offers other sizes and quantities by request.

Metallics lists the JFWP44 for the electrical, plumbing, heating and air conditioning trades. At #12 diameter and 3 inches it is the size reached for when anchoring strut, backboards, plywood mounting panels, box mounting brackets, and hanger hardware into wood studs or joists, where you need to get through a mounting plate and still bite deep into framing.
