Metallics JFWP25 – Frequently Asked Questions
1) Can I use these on a federally funded or Buy American job?
No. The JFWP25 screws are listed as not Buy American compliant and not ARRA compliant, with multiple countries of origin. If your project carries a domestic sourcing requirement, these will not satisfy it and you need a domestically manufactured fastener.
2) What driver bit do I need for the Metallics JFWP25 wood screws?
A #2 Phillips bit. The JFWP25 is a flat head Phillips drive screw, and the recess runs 0.191 to 0.204 inch in diameter with a 0.113 to 0.136 inch depth, which is standard #2 territory. Stock #2 bits in the van and these drive without cam-out.
3) How many 8 x 3-1/2 in. Metallics wood screws come in a jar?
They ship 100 to a jar, and the jar is the minimum order unit. Jar weight is listed at 1.679 lbs. Other sizes and quantities are available by request.
4) Will a flat head screw sit flush in wood, or do I need to countersink first?
Flat head screws are made to seat flush or slightly below the surface, and the JFWP25 head is only 0.100 inch high with a 0.292 to 0.332 inch head width, so the countersink is shallow. In softwood the tapered point and flat head will usually self-seat as you drive; in hardwood or where you want a clean flush face, pre-drill and countersink to the head width.
5) Are these #8 wood screws suitable for outdoor or damp locations?
These are zinc plated steel. Zinc plating handles indoor and occasionally damp conditions, but it is not a marine or sustained-wet finish. For exterior decking, treated lumber, or anything that stays wet, go to a stainless or coated exterior screw instead.
6) How much of the 3-1/2 inch screw is actually threaded?
Threading on the JFWP series follows the rule of 2/3 of the length on screws over 1 inch, so on a 3-1/2 inch screw expect roughly the lower two thirds threaded with a shank up near the head. That unthreaded shank is what lets the top board pull tight to the bottom one. Thread pitch is 15 threads per inch.
7) Do these Metallics screws meet a recognized dimensional standard for spec work?
Yes. The JFWP wood screws are built to ASME B18.6.1, with thread dimensions to ASME B18.6.1-1997. That is the governing standard for wood screws, so head, recess, and thread dimensions are interchangeable with any other B18.6.1 #8 wood screw.
