Metallics JFWP46 – Frequently Asked Questions
1) Will a #12 x 4 inch flat head wood screw sit flush in a countersunk hole?
Yes, if the countersink is cut for it. The flat head measures 0.389 to 0.438 in. across with a head height of 0.132 in., and it is built to ASME B18.6.1, so a standard 82 degree countersink for a #12 flat head wood screw will bring it flush with the surface.
2) Does the Metallics JFWP46 wood screw meet Buy American requirements?
No. The JFWP46 is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. On federally funded or domestic preference work, this one will not clear the submittal.
3) Is a zinc plated steel wood screw okay for outdoor or damp locations?
Zinc plated steel, like the JFWP46, is a dry interior fastener. The plating gives modest corrosion resistance but it is not a substitute for stainless or hot dip galvanized in weather exposure, pressure treated lumber, or wet service. For exterior framing or treated wood, specify a stainless or galvanized wood screw instead.
4) Do I need to pre-drill for a #12 x 4 in. tapered point wood screw?
Yes, in hardwood and in any situation near an edge or end grain. This is a traditional tapered point wood screw at 11 TPI, not a self-drilling or auger point screw, so a pilot hole plus a clearance hole for the unthreaded shank keeps the wood from splitting and stops the head from mushrooming the surface.
5) What is this 4 inch wood screw actually used for on a job?
Metallics lists the JFWP series for the electrical, plumbing, heating and air conditioning trades. At #12 diameter and 4 inches long, it is the size you reach for anchoring strut, backer boards, panel and equipment mounts, and unistrut blocking into wood framing where a short screw will not reach through the substrate into solid material.
6) What standard are these Metallics wood screws made to?
Dimensions follow ASME B18.6.1 and the threads follow ASME B18.6.1-1997. That matters if you are matching existing fasteners or writing a spec: head, recess and thread geometry are to the published standard rather than proprietary, so a standard #3 Phillips bit and a standard #12 flat head countersink both apply.
7) How much does a jar of 100 of these 4 inch screws weigh?
2.78 lbs per jar, with jar dimensions given as 7.25 in., 4.5 in. and 4.5 in. Useful if you are planning a van stock load or counting shelf space in the shop.
