Metallics JFWP20 – Frequently Asked Questions

1) Will a #8 x 1-1/4 inch flat head wood screw sit flush when mounting an electrical box to a stud?
Yes, the flat head is made to countersink flush. Head diameter runs 0.292 to 0.332 inch with a head height of 0.100 inch, so it seats into a countersunk or chamfered mounting hole and leaves nothing proud to interfere with a box, bracket, or cover plate. If you are fastening through a flat steel bracket with a plain punched hole, the head will stand about 0.100 inch above the metal instead.
2) Is this a wood screw or a sheet metal screw? I need something that bites into framing lumber.
It is a wood screw. The JFWP20 has a tapered point and 15 threads per inch, the coarse, tapering thread form meant to pull into softwood framing without splitting it. It is not intended to cut into sheet steel or strut; for metal studs or duct you want a self drilling or sheet metal screw.
3) Are these screws Buy American or ARRA compliant for a federal or public works job?
No. The JFWP20 wood screw is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your contract carries a domestic sourcing clause, this one will not qualify on the paperwork.
4) What driver bit do I need for the Metallics JFWP20 wood screws?
A #2 Phillips bit. The JFWP20 is a Phillips drive screw and the recess is cut to 0.191 to 0.204 inch diameter with 0.113 to 0.136 inch depth, which is the standard #2 engagement. Keep a fresh bit in the gun; a worn #2 will cam out of a recess that shallow.
5) Can I use these zinc wood screws outdoors or in a damp crawlspace?
These are steel with a zinc finish, which is a corrosion-resistant coating for dry interior and protected work, not a marine or fully exterior fastener. Fine for boxes, strut backing, duct hangers, and pipe supports inside a structure. For sustained wet exposure, treated lumber contact, or coastal air, use a stainless or hot dip galvanized screw instead.
6) Do these Metallics screws meet a recognized dimensional standard for spec work?
Yes. The JFWP20 is built to ASME B18.6.1 for dimensions, with threads to ASME B18.6.1-1997. That is the standard a submittal for wood screws is normally written against, so head size, recess, and thread pitch will match what the drawing calls for.
7) Do I need to pilot drill for a #8 x 1-1/4 wood screw?
In softwood framing the tapered point will usually start and pull on its own. In hardwood, plywood edges, or anywhere close to the end of a board, drill a pilot, because a coarse 15 TPI wood screw thread generates enough radial force to split the piece. If you want the flat head truly flush, countersink the top of the pilot to take the 0.292 to 0.332 inch head.
8) How many screws come in a jar of Metallics JFWP20?
100 screws per jar, and the jar is the order minimum unit. The whole pack weighs 0.61 lbs, so it drops in a pouch or on a van shelf without taking a bin.
9) What trades and jobs is the Metallics JFWP20 screw meant for?
It is catalogued for the electrical, plumbing, and heating and air conditioning trades. In practice that is box and bracket mounting, conduit and pipe support straps, duct hanger backing, and panel or fixture mounting into wood framing. At 1-1/4 inch, it is the length that gets through a strap or bracket and still has most of its thread in the stud.
