Metallics JRM79SLT – Frequently Asked Questions

1) What thread size and length are the Metallics JRM79SLT machine screws?
The JRM79SLT is a 3/8-16 machine screw, 1-3/4 inches long. The 16 threads per inch is the UNC coarse pitch for 3/8 diameter, so it mates with standard 3/8-16 nuts, tapped holes, and strut channel nuts.
2) How strong are these zinc plated steel machine screws?
Minimum tensile strength is 60,000 psi, with a hardness of Rockwell B70 to B100, made from AISI 1006-1022 low carbon steel. That is standard commercial low carbon machine screw strength, fine for fixture mounting, enclosure and box work, and general equipment assembly. For structural or high load joints you want a graded cap screw instead.
3) Will these Metallics screws satisfy a Buy American requirement on a federal job?
Metallics flags the JRM79SLT as ARRA compliant and Buy American compliant, while listing China as country of origin. For a federally funded project, give both of those to your compliance reviewer, since the clause applied to your contract decides what counts.
4) How big is the round head on these 3/8-16 slotted screws, and will it cover an oversized hole?
Head width runs 0.67 to 0.708 in. and head height 0.237 to 0.256 in. That dome is roughly twice the 3/8 shank diameter, so it bridges a slightly enlarged or slotted hole, but it sits proud of the surface. If you need the head flush, a round head is the wrong profile.
5) Are these Metallics screws okay for outdoor or damp locations?
These are steel with a zinc plated finish. Zinc plating handles indoor and protected areas well, but it is a sacrificial coating, not stainless. For direct weather exposure, wash down areas, or coastal sites, specify a stainless machine screw in the same 3/8-16 x 1-3/4 size.
6) How do the JRM79SLT machine screws come packaged and what is the minimum order?
They ship in a jar of 100. The order minimum is 100 count, so the jar is the buying unit, not a loose single screw. Packed weight for the jar is 0.65 lbs.
7) Do these machine screws come with nuts or washers?
No. The JRM79SLT is the screw only, 100 to a jar. If you are through bolting rather than driving into a tapped hole, order 3/8-16 hex nuts and washers separately.
8) How much material can a 1-3/4 inch long 3/8-16 screw actually fasten?
The 1-3/4 in. length is measured under the round head, so the full 1-3/4 in. is available for grip plus thread engagement. Subtract your combined material thickness from that to see how much thread lands in the nut or tapped hole; you want at least one diameter, about 3/8 in., engaged.
