Metallics JBSC1038 – Frequently Asked Questions

1) What thread does a 10-24 x 3/8 in. socket button head cap screw take, and will it thread into a standard 10-24 tapped hole?
It's a #10-24 UN thread at 24 threads per inch, made to ANSI/ASME B1.1, so it threads into any standard 10-24 tapped hole or 10-24 nut. Thread length is short at 3/8 in. overall screw length, so plan on a grip that doesn't exceed that.
2) Can I use these black alloy steel button head cap screws in a high-strength structural connection?
No. Metallics states these are not recommended for critical, high-strength applications. Rated pull is 2440 lb minimum tensile, and hardness runs Rockwell C39-44. For anchoring or structural work, specify a fastener rated for that duty instead.
3) Are the Metallics JBSC1038 screws Buy American or ARRA compliant for a government job?
No on both counts. These are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. If your contract carries a domestic sourcing clause, these will not qualify.
4) What driver do these socket button head screws take?
Hex drive, driven with a hex key (Allen) in the socket recess, not a Phillips or slotted bit. Socket depth is 0.07 in., so seat the key fully before applying torque to avoid rounding the recess.
5) Is the black finish on the Metallics BSC series screws a corrosion coating suitable for outdoor or wet locations?
No. The material is alloy steel with a black oxide type appearance and the screws are supplied plain, meaning there's no plated corrosion protection. Keep them to dry interior work. For damp, exterior, or washdown locations choose a stainless or zinc plated cap screw.
6) How are these 10-24 cap screws packaged and what's the minimum I can buy?
They come in a jar of 100 pieces, and 100 is the order minimum, so the smallest purchase is one full jar. Useful for MRO crib stock where small socket screws get consumed a handful at a time.
7) Do these socket button head screws meet a recognized dimensional spec for submittal?
Yes, they're built to ASME B18.3-2012 for socket cap screw dimensions, with threads to ANSI/ASME B1.1. That pair of references is what a spec reviewer or purchasing agent usually wants to see on a fastener submittal.
8) What are these small button head cap screws typically used for in the trades?
Metallics lists them for electrical, plumbing, heating and air conditioning work, the kind of 10-24 machine screw duty you hit on enclosure covers, mounting brackets, and equipment panels. The rounded head and hex socket give a low profile with a drive that won't cam out like a Phillips.
9) Can I get this socket button head screw in a longer length or a different quantity?
Yes, Metallics offers other sizes and quantities in the BSC socket button head line by request. The JBSC1038 itself is fixed at 10-24 x 3/8 in. in alloy steel black, so if you need more grip length, ask for the longer length in the same series rather than stacking washers.
