Metallics JFWPB13 6 x 1-1/2 in. Flat Head Phillips Wood Screws - Brass - Each

No. On this series, a screw of 1 inch or longer carries thread over roughly two thirds of its length, so a 1-1/2 inch #6 screw has about an inch of thread and a plain shank under the head. That unthreaded shank is what lets the screw clamp two pieces of wood together instead of jacking them apart. Thread pitch is 18 threads per inch.

No. These are listed as not Buy American compliant and not ARRA compliant, with multiple countries of origin. If your contract carries a domestic-content clause, this part will not satisfy it and you need a domestically produced brass wood screw instead.

A #2 Phillips bit. The JFWPB13 is a Phillips drive screw with a #2 driver size, and the recess measures 0.161 to 0.174 inch in diameter at 0.083 to 0.106 inch deep. Brass is soft, so a correctly seated #2 bit matters more here than on a steel screw, since an undersized bit will chew the recess out before the head seats.

They're built to ASME B18.6.1, with thread dimensions to ASME B18.6.1-1997. That's the wood screw standard, so head, recess, and thread geometry are to a documented spec rather than a house dimension, which is what a submittal or an institutional purchase order usually needs to see.

The JFWPB13 ships 100 screws to a jar, and the jar is the order minimum. If you only need a dozen, you're still buying the hundred count, which is normally the cheaper way round for anyone doing repeat cover plate or trim work.

Two reasons drive it. Brass won't rust-stain finished woodwork or damp locations the way bare steel does, and it matches brass trim, hinges, and plates visually so the fastener isn't the thing you notice. The trade-off is strength: brass is softer than steel, so pilot-drill hardwood and drive it slowly or you'll twist the head off. For structural pull-out loads, use a steel screw and save these for trim, plates, and finish work.

That's the intended use. Metallics lists the field application as the electrical, plumbing, heating and air conditioning industries, and the #6 x 1-1/2 in. flat head size is the common one for anchoring straps, boxes, and plates into wood framing or trim. The flat head keeps the fastener below the surface of a plate or strap.

A jar comes in at 0.67 lbs, and the packaged jar measures 3 x 2.15 x 3 inches. Useful if you're consolidating a van stock order or figuring freight on a bulk fastener line.
