Metallics JRM94SLT – Frequently Asked Questions
1) Do these Metallics machine screws meet Buy American and ARRA requirements on a public job?
Metallics lists the JRM94SLT as both ARRA compliant and Buy American compliant. Country of origin is China. On a federal or state funded project where the specification calls out a domestic melt and manufacture requirement rather than the ARRA/BAA compliance designation, confirm which standard your spec is written to.
2) How many screws come in a pack of the Metallics JRM94SLT?
They ship 100 to a jar, and 100 count is the order minimum. Package weight is listed at 0.95 lbs. If you need a different count, Metallics offers other sizes and quantities by request.
3) Is a round head slotted screw the right choice, or should I use a flat head?
Round head sits proud on the surface with a domed crown, so use it where the screw head can stand above the material and you want full bearing on the part being held. Head width runs 0.334 to 0.359 in. and head height 0.123 to 0.137 in. If the head has to sit flush in a countersunk hole, you want a flat head instead, not this one.
4) Are these zinc plated screws OK for damp or outdoor locations?
The JRM94SLT is carbon steel with a zinc finish, which handles indoor and protected locations well but is not a marine or sustained wet-location material. For exterior exposure, washdown areas, or coastal work, step up to a stainless machine screw in the same 10-24 x 1-1/4 in. size.
5) What is the strength rating on these 10-24 steel machine screws?
Minimum tensile strength is 60,000 psi, with hardness of Rockwell B70 to B100, made from AISI 1006 to 1022 low carbon steel. That is standard commercial grade machine screw material, fine for device mounting, panel work, and general fastening. It is not a graded structural fastener, so do not substitute it where a drawing calls for a Grade 5 or Grade 8 bolt.
6) Will a 10-24 machine screw work in a tapped hole or do I need a nut?
A machine screw has a uniform straight machine thread, so the JRM94SLT works either way: threaded into a tapped 10-24 hole, or run through a clearance hole with a 10-24 nut behind it. It is not a self-tapping or sheet metal screw, so it will not cut its own thread in an untapped hole.
7) Is the 1-1/4 inch length the shank or the overall screw length?
On a round head machine screw the 1-1/4 inch length is measured from the underside of the head to the point, so the domed head height, 0.123 to 0.137 in., sits on top of that. Allow for it when you are figuring stack-up through a ring and into a tapped strap.
