Metallics JFWP89 14 x 2-1/2 in. Flat Head Phillips Wood Screws - Steel Zinc - Each

Yes, if the countersink matches the head. The JFWP89 has a flat head measuring 0.452 to 0.507 inch across with a head height of 0.153 inch, so it needs a countersink cut to roughly a half inch at the surface to pull flush. In softwood the flat head will often sink itself; in hardwood or plywood, counterbore first or the head will crush the fibers instead of seating.

Zinc plating on steel is a light corrosion coating meant for dry, indoor, protected work. The JFWP89 is steel with a zinc finish, which is fine for interior framing, blocking, strapping, and mounting electrical boxes or panels to wood studs. For exterior decks, pressure treated lumber, or wet locations, go to a stainless or hot dip galvanized screw instead, since zinc plating will bleed and fail in those conditions.

They ship as a jar with a 100 count minimum. The JFWP89 order minimum is 100 CT in jar packaging, so that is the smallest quantity on an order. Metallics notes other sizes and quantities are available by request if you need a different configuration.

Yes, in most cases. A #14 is a heavy screw with a tapered point and 10 threads per inch, and the tapered point starts the hole but does not clear material the way a self drilling point does. In hardwood, oak blocking, or near an edge or end grain, drill a pilot or you will split the wood or snap the screw. In soft pine blocking you can often drive it straight in.

They are built to ASME B18.6.1, with threads to ASME B18.6.1-1997. That is the wood screw dimensional standard covering head, recess, and thread geometry, so head width, head height, and recess dimensions are all held to published tolerances rather than being a house spec. Useful if your spec section calls out a standard rather than a brand.

Country of origin on the JFWP89 is listed as multiple, and both the ARRA and Buy American compliance flags come through as undetermined rather than as a yes. If your contract has a domestic sourcing requirement, treat this item as unverified for that purpose and confirm origin for the specific lot before you submit it.

About 2.28 lbs for the jar. Light enough to carry a handful of jars on a service van without thinking about it, which matters if you are standardizing fastener stock across several trucks or a stockroom shelf.
