Metallics RSDS5V – Frequently Asked Questions
1) Do I have to pre-drill a pilot hole for these Type 17 deck screws?
No. The RSDS5V carries a Type 17 point, whose chip cavity (auger point) lets the screw drive without pre-drilling a pilot hole, including in denser woods. That is the main reason crews run Type 17 on deck boards instead of a plain gimlet point.
2) How does yellow zinc hold up on an exterior deck?
Yellow zinc dichromate is a plated finish, not a coating built for long-term ground contact or chemically treated lumber. The RSDS5V is steel with a yellow zinc dichromate finish, which suits dry or protected framing, interior subfloor, and general carpentry. For exposed, weather-washed decking or ACQ-treated lumber, a coated or stainless deck screw is the better call.
3) Will a bugle head deck screw sit flush with the decking, or do I need to counterbore?
The bugle head self-countersinks into softwood decking, so it pulls flush without a counterbore. Head height on the RSDS5V is 0.124 in. and head width runs 0.316 to 0.358 in., so the bearing surface is small enough to sink into a 5/4 board but wide enough to hold it down.
4) How many Metallics RSDS5V screws come in a jar, and what is the minimum order?
The RSDS5V ships in a jar of 500, and 500 count is the order minimum. Jar weight is listed at 6 lbs. The description notes other sizes and quantities are available by request.
5) Does the #9 x 2-1/2 in. size refer to diameter or thread count?
Both numbers get used. The RSDS5V is a #9 diameter screw 2-1/2 inches long, with 9 threads per inch in a UNC coarse thread form. The deeper coarse thread is what gives it resistance to pull-out in wood.
6) Are Metallics RSDS5V deck screws acceptable on a federally funded or Buy American job?
The RSDS5V is flagged compliant for both Buy American and ARRA requirements. Country of origin is listed as multiple, so if your specification demands a single documented origin, request the mill paperwork for the lot you receive.
7) What steel are these deck screws made from?
AISI 1018 to 1022 low-carbon steel is the material standard for the RSDS5V, case hardened in the usual way for a Type 17 point screw and finished in yellow zinc dichromate. That is a drive-in wood screw steel, not a structural fastener grade, so do not substitute it where a structural wood screw or lag is specified on the drawing.
8) Do deck screw dimensions vary between manufacturers?
They do. There is no single industry standard for deck screws, so the Metallics RSDS5V dimensions (0.124 in. head height, 0.316 to 0.358 in. head width) are offered as a guide and slight deviations are acceptable. If you are matching screws already in a deck, check head width and drive size rather than assuming a #9 x 2-1/2 is identical across brands.
