Metallics JCPD5 10 x 3-1/2 in. Bugle Head Square & Phillips Deck Screws - Steel Ceramic - Type 17 - Coarse Threads - Each

Yes. The JCPD5 carries a ceramic polymer coating over steel that is rated for use in pressure treated lumber and resists corrosion for roughly twice as long as dacrotized steel deck screws. It also holds up to UV exposure, so it suits exposed decking and exterior framing work.

The JCPD5 uses a Type 17 point, which is the self-drilling auger tip cut into the end of the screw. It clears its own chip channel in wood, so you can drive it without pre-drilling in most decking and framing lumber. Near board ends or in dense hardwood, a pilot still reduces splitting.

No. The JCPD5 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On federally funded work with domestic sourcing requirements, you will need a different fastener.

A #2 bit. The head takes a combination square/Phillips recess, so either a #2 square drive or a #2 Phillips will run it. The square recess measures 0.110 to 0.113 in. wide and 0.064 to 0.075 in. deep; the Phillips recess is 0.190 to 0.204 in. across and 0.124 in. deep. Crews that already run #2 square bits on decking do not need to change tooling.

Yes. The bugle head is a shallow profile, 0.020 to 0.039 in. high with a 0.334 to 0.363 in. head diameter, and it pulls itself flush into softwood decking as it seats. Head dimensions are given as a guide since there is no single industry standard for bugle heads, so minor deviation is normal.

At 3-1/2 in. long, the JCPD5 is sized for 2x decking or doubled 5/4 material into a joist, leaving solid thread engagement below the board. For standard 5/4 or 1x decking, a shorter screw is the better call; 3-1/2 in. is a framing-depth length.

Coarse, at 8 threads per inch on a UNC thread form. Coarse pitch is what you want in wood and pressure treated lumber, since it bites fast and resists pull-out better than a fine pitch in soft fiber.

They ship in a jar of 100, and 100 is the order minimum. Jar weight is listed at 1.86 lbs. Other sizes and quantities are available by request.

Metallics lists the CPD series for electrical, plumbing, heating and air conditioning work as well. Contractors use them for mounting strut, backer boards, equipment blocking and wood-framed anchoring where a corrosion coated screw is called for, not just for deck boards.
