Metallics JFW122 – Frequently Asked Questions
1) Will a #4 x 1 inch flat head screw sit flush when mounting a device plate or a small strike?
Flat head screws seat flush in a countersunk hole, and the JFW122 head measures 0.195 to 0.225 inch across with a head height of 0.067 inch. If the plate you are fastening has a countersink matched to a #4 screw, the head drops level with the surface. A plate with a flat, non-countersunk hole will leave the head proud.
2) How many Metallics JFW122 wood screws come in a pack, and how are they packaged?
The JFW122 ships 100 screws to a jar, and 100 count is the order minimum. Jar packaging keeps loose #4 screws contained on a cart or in a van bin rather than scattering through a bag.
3) How much of the Metallics JFW122 screw is threaded?
At the 1 inch length, roughly two thirds of the shank is threaded, running 22 threads per inch to a tapered point. The unthreaded shank under the head lets the top piece pull tight against the substrate instead of the threads jacking it apart.
4) Do I need a pilot hole for these #4 wood screws?
The JFW122 has a tapered point, not a self-drilling tip, so it is meant to follow a pilot hole in hardwood or near an edge where splitting is a risk. In soft pine or plywood it will usually start on its own. The tapered point is also what lets it draw itself straight into the pilot.
5) What screwdriver bit fits the Metallics JFW122?
Slotted drive only, with a slot 0.031 to 0.039 inch wide and 0.02 to 0.03 inch deep. Use a narrow cabinet-tip flat blade that fills the slot; a wide or thick blade will ride up and cam out of a shallow #4 slot. There is no Phillips or square recess on this screw.
6) Are these zinc wood screws okay for outdoor or damp locations?
The JFW122 is steel with a zinc finish, which handles indoor and dry-location work and gives some corrosion resistance in occasional damp. For sustained exterior exposure, treated lumber, or coastal air, go to a stainless or hot dip galvanized wood screw instead; plain zinc plating will not hold up long term there.
7) Do the Metallics JFW122 screws meet a recognized dimensional standard for ordering against a spec?
Head, slot, and thread dimensions follow ASME B18.6.1, with the thread referenced to ASME B18.6.1-1997. That matters if your submittal calls out a standard wood screw rather than a proprietary fastener, because any #4 x 1 inch flat head slotted screw built to that standard interchanges with it.
8) Is a #4 x 1 inch screw big enough for mounting electrical boxes or conduit straps to wood?
A #4 is a light-gauge screw. It suits small device plates, low voltage brackets, chase nipples, and trim work where the hole is already sized for a #4. For a box or strap carrying real load, step up to a #6, #8, or #10 wood screw. The JFW122 is 1 inch long, so it also needs at least that much sound wood behind the item.
9) Are these Metallics wood screws Buy American or ARRA compliant for a public project?
Metallics flags the JFW122 as compliant on both the ARRA and Buy American attributes, with country of origin China. Verify against the specific procurement clause on your job, since those two designations carry different sourcing tests.
