Metallics JRM87SLT – Frequently Asked Questions
1) Do these screws meet Buy American or ARRA requirements for a public works job?
The JRM87SLT is flagged as both ARRA compliant and Buy American compliant in the manufacturer's data, with country of origin listed as China. On a federally funded project where the specification requires domestic melt and manufacture rather than the broader compliance flag, confirm which standard your spec is written to before you submit these.
2) How many screws come in a pack of these Metallics 8-32 round head screws?
They ship in a jar of 100 pieces, and 100 count is the order minimum. The filled jar weighs 0.73 lbs.
3) How much clearance does the round head need over the surface?
The round head measures 0.287 to 0.309 in. across and stands 0.107 to 0.12 in. tall, so figure on about an eighth of an inch of head projection above the work. Round heads are domed and bear on the surface rather than drawing flush, so if you need the screw to sit flat in a countersunk hole this is the wrong head style.
4) Are these steel zinc screws strong enough for structural or load-bearing fastening?
These are low carbon steel screws, AISI 1006 to 1022, with 60,000 psi minimum tensile strength and Rockwell B70 to B100 hardness. That is standard commercial machine screw strength, fine for mounting devices, plates, brackets, and enclosure hardware. For a graded structural connection you want a Grade 5 or Grade 8 cap screw instead, not a low carbon machine screw.
5) Can I use these Metallics zinc screws outdoors or in a damp location?
The finish is zinc plating over steel, which handles indoor and dry locations well but is only a sacrificial coating. In wet, coastal, or washdown areas it will eventually rust through. Use a stainless machine screw in the same 8-32 x 1-1/4 size for those spots.
6) Is the JRM87SLT a blunt machine screw thread or a self-tapping screw?
It is a straight machine screw: a uniform 8-32 thread, 32 TPI, meant to go into a pre-tapped hole or to be paired with a nut. It will not cut its own thread in sheet metal or plastic. For that you want a self-tapping or sheet metal screw.
7) What is the exact part number to order the 8-32 x 1-1/4 in. round head slotted screw from Metallics?
Order Metallics part JRM87SLT, from the JRM series. That number covers the 8-32 x 1-1/4 in. round head slotted machine screw in zinc plated steel, packed 100 to a jar.
