Metallics JBSC1458 – Frequently Asked Questions
1) What thread and length is the Metallics JBSC1458 button head cap screw?
It's a 1/4-20 screw with a 5/8 inch length, 20 threads per inch, Unified (UN) thread form made to ANSI/ASME B1.1. So it mates with any standard 1/4-20 tapped hole or nut, including strut and channel nuts cut for 1/4-20.
2) Will these screws satisfy a Buy American or ARRA domestic-content requirement on a federal job?
No. The JBSC1458 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your specification carries a domestic-content clause, these cannot be submitted against it.
3) Are these black screws plated or coated for outdoor use?
They are alloy steel with a black finish and are supplied plain, meaning no added plating or corrosion coating. Keep them to dry indoor and enclosed work. For wet locations, exterior runs, or washdown areas, go with a stainless or hot-dip galvanized fastener.
4) Do these screws meet a recognized dimensional standard for socket screws?
Yes, the JBSC1458 is made to ASME B18.3-2012, the standard that governs socket cap screw head and socket dimensions, with threads to ANSI/ASME B1.1. If a drawing calls out B18.3 button head socket screws in 1/4-20, this answers that callout.
5) How are these sold, loose or in a box?
They ship in a jar of 100, and 100 pieces is the order minimum. Metallics notes that other sizes and quantities are available by request, so if your job needs a different length in the same 1/4-20 thread it can be sourced.
6) What size hex key drives these button head socket screws?
They take a hex (Allen) key, not a slotted or Phillips driver. The internal socket is 0.087 inch deep, so use a key with enough engagement and keep it fully seated. Button head sockets have a shallower socket than standard socket caps, which is why a worn or undersized key strips them easily.
