Metallics JSBH131 – Frequently Asked Questions
1) Is the Metallics JSBH131 hex bolt 316 stainless or 18-8?
316 stainless steel. The molybdenum in 316 gives it better corrosion resistance than 18-8 and better strength at elevated temperature, which is why it gets specified for coastal, wash-down, and chemical-exposure work rather than dry interior fastening. If you are only fastening indoors and dry, 18-8 is the cheaper austenitic option.
2) What thread does the JSBH131 take, and what nut do I need?
It is a 5/16-18 bolt, so 18 threads per inch in the coarse (UNC) 5/16 series, with a measured outside diameter of 0.3065 to 0.3125 inch. Pair it with a standard 5/16-18 hex nut. For 316 work, use a 316 or 18-8 stainless nut so you are not introducing a carbon steel part that will rust and seize the joint.
3) Does the Metallics JSBH131 bolt meet Buy American or ARRA requirements for a public project?
No. It is not Buy American compliant and not ARRA compliant, and country of origin is listed as multiple. If your specification carries a domestic-content clause, this jar will not satisfy it and you need a domestically produced 5/16-18 stainless bolt instead.
4) What wrench or socket size fits the head on this 5/16-18 hex bolt?
Head width across flats runs 0.489 to 0.500 inch, so a 1/2 inch wrench or socket is the size to bring. Head height is 13/64 inch, worth knowing if you are working into a counterbore or under a tight cover plate.
5) How strong is the Metallics 316 stainless hex bolt compared with a plated grade 5?
Tensile is 100,000 to 150,000 psi minimum with 65,000 psi minimum yield, and hardness runs Rockwell B95 to C32. That puts it in the range people expect from a stainless cap screw, but a carbon steel SAE grade 5 or grade 8 will carry more load. You choose 316 here for corrosion environment, not for maximum strength.
6) How many bolts come in a jar, and can I buy fewer?
They ship as a jar of 100, and the jar is the order minimum, so 100 pieces is the smallest buy. Metallics does offer other sizes and quantities by request if 1-1/2 inch length or the 100 count does not suit the job.
7) Is this hex bolt suitable for outdoor electrical strut and enclosure work?
Yes, that is the intended use. Metallics lists the field application as the electrical, plumbing, heating and air conditioning industries, and the 316 stainless material handles outdoor, damp, and chemical exposure where plated steel strut hardware rusts out. Common uses are mounting enclosures, clamps, and channel brackets on exterior walls and rooftops.
