Metallics JSBH231 – Frequently Asked Questions
1) Is the Metallics JSBH231 1/4-20 hex bolt 316 stainless or 18-8 stainless?
316 stainless steel. The molybdenum in 316 gives it better corrosion resistance than 18-8 and holds strength better at elevated temperatures, which is why it gets specified for coastal, wash-down, and chemical-exposure work rather than dry interior fastening.
2) What thread does the JSBH231 hex bolt take, and will it thread into a standard 1/4-20 nut or tapped hole?
It is a 1/4-20 UNC bolt, 20 threads per inch, with a measured shank diameter of 0.2450 to 0.2500 in. That mates with any standard 1/4-20 nut, tapped hole, or strut channel nut. Pair it with a 316 stainless nut and washer if you want the corrosion resistance to carry through the whole joint rather than stopping at the bolt.
3) Is a 316 stainless 1/4-20 hex bolt strong enough for structural strut and hanger work?
Tensile strength is 100,000 to 150,000 psi minimum with a 65,000 psi minimum yield and hardness of Rockwell B95 to C32. That covers typical electrical, plumbing, and HVAC support work: strut, clamps, hangers, enclosure mounting. For a rated structural steel connection where the drawing calls out a specific grade bolt, use the bolt the spec names instead.
4) Can I use these stainless bolts on a federally funded job with Buy American requirements?
No. The JSBH231 is listed as not Buy American compliant and not ARRA compliant, with country of origin recorded as multiple. If your project has domestic-content requirements, you need a bolt sourced and documented as domestic.
5) What wrench or socket size fits the head on this 1/4-20 stainless hex bolt?
The head is a hex measuring 0.428 to 0.438 in. across the flats, so a 7/16 in. wrench or socket is the fit. Head height runs 0.150 to 0.163 in.
6) How is the Metallics JSBH231 packaged, and how many bolts do I get?
They ship in a jar of 100, and the jar is the order minimum, so you buy in full jars rather than loose counts. Shipped weight of the filled jar is 676 g. Handy for a service van or a shop bin rather than bulk-box quantities.
7) Will a 1/4-20 x 3/4 bolt be long enough for my clamp or bracket?
The 3/4 in. length is grip plus head seat, so it suits thin stacks: a single strut channel with a nut, a bracket to an enclosure, a clamp body to a backing plate. Once you are stacking two pieces of strut, a washer each side, and a nut, 3/4 in. runs out of thread and you want a longer bolt. Metallics builds this hex bolt in other lengths in the same SBHC and JSBHC series.
8) What is the difference between the 316 stainless hex bolt and the 18-8 stainless version?
Both are austenitic stainless. The 316 adds molybdenum, which buys more corrosion resistance than 18-8 and better strength at high temperature. Use 316 where there is salt air, moisture, or chemical exposure, such as rooftop and coastal mechanical work. Where the fastener lives indoors and dry, 18-8 does the same mechanical job.
