Metallics JSRM95 – Frequently Asked Questions
1) What thread size and length are the Metallics JSRM95 machine screws?
The JSRM95 is a 1/4-20 machine screw, 2 inches long, with 20 threads per inch. That is the standard coarse 1/4 inch machine screw thread, so it mates with a 1/4-20 tapped hole or nut.
2) Will a round head slotted screw sit flush in a countersunk hole?
No. The round head on the JSRM95 is a domed bearing head that sits on top of the surface, with a head height of 0.16 to 0.175 inch and a head width of 0.443 to 0.472 inch. For a flush finish in a countersunk hole you need a flat head screw instead. Where the round head helps is spreading load over a slightly oversized or slotted hole in sheet metal or an enclosure flange.
3) Is this screw stainless, and will it hold up outdoors or in a damp mechanical room?
The JSRM95 is 18-8 stainless, the common 300 series austenitic stainless used for corrosion resistance. That makes it a reasonable choice for exterior boxes, wet rooms, and mechanical spaces where a plain zinc plated screw would rust. Hardness runs Rockwell B85 to B95.
4) Are Metallics JSRM95 screws Buy American or ARRA compliant?
No on both counts. The JSRM95 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. For a federally funded or domestic-preference job, specify a domestic fastener instead.
5) How many screws come in a jar of Metallics JSRM95, and can I buy just a few?
These ship as a 100 piece jar, and 100 is the order minimum. If you only need a handful for one box or panel, you are still buying the full jar, which is why it suits crews who repeat the same mounting work rather than a one-off repair.
6) What tensile strength do these 18-8 stainless machine screws have?
Rated at 80,000 psi minimum tensile. Worth knowing that Metallics states tensile values for stainless screws as approximations, since there is no single performance standard for stainless machine screws. If a drawing calls out a specific graded strength, a stainless machine screw is not the fastener to meet it.
7) What are 1/4-20 x 2 in. round head slotted machine screws typically used for on the job?
Metallics lists the application as the electrical, plumbing, heating and air conditioning trades. At 2 inches of length, the usual work is through-bolting with a nut, mounting equipment to strut or channel, hanging brackets, and fastening through thicker assemblies where a short screw bottoms out. Thread engagement is what matters, so match the 2 inch length to your stack-up plus nut.
8) How much does a jar of these 1/4-20 x 2 in. stainless screws weigh?
The 100 count jar comes in at 2.6 lbs, with the packed jar measuring 3 in by 3 in by 4.57 in. Useful if you are staging a van or kitting out a cart.
