Metallics JFWP45 – Frequently Asked Questions
1) What size driver bit do I need for Metallics JFWP45 wood screws?
A #3 Phillips bit. The JFWP45 is a #12 diameter screw with a Phillips recess measuring 0.270 to 0.283 inch in diameter and 0.148 to 0.171 inch deep, which is why a #2 bit will cam out on it. Keep a #3 in the pouch if you are driving these all day.
2) How much of a 3-1/2 inch #12 wood screw is actually threaded?
On the JFWP45, thread runs roughly two thirds of the 3-1/2 inch length, leaving an unthreaded shank under the head. That shank is what pulls two pieces of wood tight instead of the thread jacking them apart, so bore a clearance hole in the top member and let the thread bite only the bottom one. Thread pitch is 11 threads per inch and the point is tapered.
3) Can I use zinc plated wood screws outdoors or in a damp location?
Zinc plated steel is a dry, indoor-rated finish. The JFWP45 is steel with a zinc plating, which handles interior framing, backboards and equipment mounting fine but will rust in exposed or wet locations and will corrode faster against treated lumber. For outdoors, pressure treated wood or any damp pit or vault, move to a stainless or hot dip galvanized wood screw instead.
4) Will these screws satisfy a Buy American or ARRA requirement on a federal job?
No. The JFWP45 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded project with domestic sourcing language in the spec, these will not pass, so a domestic fastener has to be substituted.
5) Will a flat head wood screw sit flush, or do I need to countersink it?
Countersink it. The JFWP45 has a flat head, 0.132 inch high with a head width of 0.389 to 0.438 inch, so it needs a matching 82 degree countersink to finish flush. Drive it into bare wood without one and the head will stand proud or crush the fibers. In softwood the head will often self-countersink, but anything hard or anything that has to be flush under a plate wants a countersink bit.
6) How are Metallics JFWP45 wood screws packaged and what is the minimum order?
They ship in a jar of 100, and 100 is the order minimum. Jar weight is 2.89 lbs. If you need a different length or a bulk count in the same JFWP flat head Phillips line, other sizes and quantities are available by request.
7) What dimensional standard do these #12 flat head Phillips wood screws meet?
The JFWP45 is built to ASME B18.6.1, with thread to ASME B18.6.1-1997. That is the standard spec sheet reference for wood screws, so head, recess and thread geometry will interchange with any other B18.6.1 #12 flat head Phillips screw and with a standard countersink prep.
