Metallics JRM134SLT – Frequently Asked Questions
1) Will a round head slotted screw sit flush in a countersunk hole?
No. The JRM134SLT has a round head that sits proud of the surface, roughly 0.16 to 0.175 inch tall and 0.443 to 0.472 inch across. If your plate or enclosure is countersunk for a flush finish, you need a flat head screw instead. The round head does give you a wider bearing surface against sheet metal, which is why it's common on device and enclosure work.
2) Can I use these screws outdoors or in a damp location?
The JRM134SLT is zinc plated steel. Zinc plating handles indoor and dry protected locations fine, but it's a sacrificial coating and will corrode in wet, washdown, coastal, or buried conditions. For those, specify a stainless machine screw in the same 1/4-20 x 6 size.
3) How many Metallics JRM134SLT screws come in a package?
They ship 100 to a jar, and 100 count is the order minimum. So the smallest buy is a full jar of 100 pieces, not a single screw.
4) How strong are these 1/4-20 machine screws, and are they hardened?
Minimum tensile strength is 60,000 psi, with hardness in the Rockwell B70 to B100 range. The steel is AISI 1006 to 1022, a low carbon grade, so this is a standard unhardened machine screw, not a high strength cap screw. For structural or high clamp load joints, step up to a Grade 5 or Grade 8 hex bolt instead.
5) Are Metallics JRM screws Buy American or ARRA compliant for a government job?
The JRM134SLT carries a compliance flag of C for both Buy American and ARRA. Country of origin is China. On a federally funded project where domestic origin is a hard requirement, verify against your contract's specific clause before you submit it.
6) Do these machine screws come with nuts or washers?
No. The JRM134SLT is sold as screws only, 100 to a jar. Order your 1/4-20 nuts, lock washers, or flat washers separately to complete the assembly.
7) What does a jar of 100 of these 6 inch machine screws weigh for shipping?
The packaged jar runs 6.52 lbs. Useful if you're ordering several counts at once for a job cart or staging a van stock.
