Metallics JFWPB29 10 x 1 in. Flat Head Phillips Wood Screws - Brass - Each

The JFWPB29 brass wood screws ship in a jar, with an order minimum of 100 pieces. So the smallest buy is a 100-count jar, not a loose each.

Use a #3 Phillips bit. The recess runs 0.245 to 0.258 inch in diameter and 0.123 to 0.146 inch deep, so a #2 bit will ride high in the recess and cam out, which matters more than usual on brass since the heads strip easily.

Yes, if the countersink matches the head. The flat head measures 0.34 to 0.385 inch across with a head height of 0.116 inch, which is the standard #10 flat head profile under ASME B18.6.1, so it seats flush in strike plates, hinge leaves and cover plates bored for #10 flat heads.

No. The JFWPB29 brass wood screw is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. If your contract carries a domestic sourcing clause, you need a domestically produced fastener instead.

At a 1 inch length, the thread runs roughly two thirds of the shank at 13 threads per inch. Figure about 2/3 inch of bite into the substrate once you account for the unthreaded shank under the head, which is what you want when you are clamping a thin plate or trim piece tight to wood.

Brass is the choice when the fastener shows or when you need to avoid a rust bloom in damp interior conditions, which is why these get specified for escutcheons, cover plates and decorative trim. The tradeoff is softness: brass has far less torsional strength than steel, so pre-drill a pilot hole and drive it slowly with a #3 Phillips. For structural or high-torque work, go to a steel or stainless wood screw instead.

Head and thread geometry follow ASME B18.6.1, with the thread specifically to ASME B18.6.1-1997. That means a #10 x 1 inch screw from this series interchanges dimensionally with any other B18.6.1 #10 flat head wood screw already in your openings, so you can mix into existing hardware without the head sitting proud.

Metallics lists the JFWPB series for the electrical, plumbing, heating and air conditioning trades. In practice that is device and cover plate mounting, strapping, and anchoring small fixtures and boxes to wood framing or blocking where a brass fastener is wanted.

Yes. The JFWPB29 is the #10 diameter by 1 inch size, and Metallics offers other sizes and quantities in the series by request. If you need a longer #10 for thicker trim or a larger jar count for a standing stock program, ask for the alternate size rather than substituting a different head type.
