Metallics JSBH255 – Frequently Asked Questions
1) Is the Metallics JSBH255 hex bolt 316 stainless or 18-8 stainless?
316 stainless steel. The molybdenum in 316 gives it greater corrosion resistance than 18-8 plus better strength at elevated temperatures, which is why it gets specified for coastal, wash-down, and chemical exposure rather than dry interior work. If you only need general indoor corrosion resistance, an 18-8 bolt of the same 3/8-16 x 2 size will do the job.
2) What thread and nut size do I need for a Metallics JSBH255 bolt?
It is a 3/8 inch diameter bolt at 16 threads per inch, so it takes a 3/8-16 nut or a tapped 3/8-16 hole. Measured shank diameter runs 0.3690 to 0.3750 inch. Note that 16 TPI is the coarse pitch for 3/8; a 3/8-24 fine thread nut will not run on it.
3) Is this bolt strong enough for structural or heavy equipment mounting?
Tensile strength is rated 100,000 to 150,000 psi minimum with a 65,000 psi minimum yield, and hardness runs Rockwell B95 to C32. That is solid for hanging electrical, plumbing, and HVAC equipment, which is the service it is built for. It is not a graded carbon steel structural bolt, so if your drawing calls out a specific SAE or ASTM structural grade, match that call-out instead.
4) Can I use these stainless hex bolts on a Buy American or ARRA funded project?
No. The JSBH255 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded job with domestic sourcing requirements you need a domestically produced hex bolt instead.
5) What wrench or socket size fits the hex head on the JSBH255?
The hex head measures 0.551 to 0.562 inch across the flats, which is a 9/16 inch wrench or socket. Head height is 15/64 inch, so it sits low enough to clear most strut and channel work.
6) Will 316 stainless bolts cause a problem fastening to galvanized strut or steel?
Mixing 316 stainless hardware with galvanized steel puts dissimilar metals in contact, and in a wet or outdoor location the zinc coating will sacrifice first. Where that matters, isolate the joint or stay with hot-dip galvanized fasteners. In dry interior runs it is routine practice, and the corrosion resistance of the 316 alloy is the reason this bolt gets picked for the electrical, plumbing, and HVAC trades in the first place.
