Metallics JRM65SLT – Frequently Asked Questions

1) What thread size and length is the Metallics JRM65SLT machine screw?
The JRM65SLT is a 5/16-18 machine screw, 1 inch long. That's 18 threads per inch on a 5/16 inch diameter, so it mates with a 5/16-18 tapped hole or a standard 5/16-18 nut. Coarse thread, not fine, so don't try to run it into a 5/16-24 hole.
2) Will a round head 5/16-18 screw sit flush, or does the head stand proud?
It stands proud. The JRM65SLT has a round head measuring 0.557 to 0.590 inch across and 0.198 to 0.216 inch high, so it seats on the surface rather than sinking into it. If you need the head buried, you want a flat head screw with a countersunk hole, not this one. The upside of the round head is bearing area: it spans a clearance hole in sheet metal or a box without needing a washer in most cases.
3) How strong is this 5/16-18 zinc machine screw, and is it strong enough for structural work?
Rated at 60,000 psi minimum tensile, made from AISI 1006 to 1022 low carbon steel at Rockwell B70 to B100. That is standard low carbon commercial fastener strength, fine for mounting boxes, panels, straps, and equipment. It is not a Grade 5 or Grade 8 fastener and should not be substituted where a drawing calls for one, or into anything carrying a structural or life safety load.
4) Can I use these zinc plated machine screws outdoors or in a damp location?
Zinc plated carbon steel, so it's for dry interior use. Zinc plating handles indoor humidity and incidental moisture, but in exterior, wet, or washdown locations it will corrode. For outdoors or a coastal site, specify a stainless 5/16-18 round head slotted screw instead.
5) How many Metallics JRM65SLT screws come in a package?
They ship 100 to a jar, and 100 count is the order minimum. So the smallest quantity you can buy is one jar of 100, not a single screw. For an electrician stocking a van or a facility buyer standardizing on 5/16-18 hardware, that's a working quantity rather than a job specific count.
6) Do these Metallics screws meet Buy American or ARRA requirements on a federally funded job?
Metallics lists the JRM65SLT as both ARRA compliant and Buy American compliant, with country of origin China. On a federally funded project, hand both of those facts to whoever is signing off on your submittal, because the compliance clause on a given contract decides how origin is treated.
7) Is the Metallics JRM65SLT a wood screw or a self tapping screw?
Neither. It's a machine screw: a straight, fully threaded 5/16-18 shank with no point, so it needs a tapped hole or a nut to hold. It will not cut its own threads in wood, drywall, or unthreaded metal. If you're driving into a hole that isn't threaded, you want a self drilling or self tapping screw instead.
