Metallics JSBH171 – Frequently Asked Questions
1) Is the Metallics JSBH171 hex bolt 316 stainless or 18-8 stainless?
316 stainless steel. The molybdenum in 316 gives it better corrosion resistance than 18-8 and more strength at elevated temperature, which is why it gets specified for coastal, wash-down, and chemical-exposure work rather than dry interior fastening.
2) What wrench or socket size fits the JSBH171 5/16-18 hex bolt head?
The hex head measures 0.489 to 0.500 inch across the flats, so a 1/2 inch wrench or socket is the correct size. Head height is 13/64 inch, which matters if you are counting on clearance under a bracket or inside a recess.
3) How strong is the Metallics 316 stainless hex bolt, and can I use it on structural connections?
Tensile strength is 100,000 to 150,000 psi minimum with a 65,000 psi minimum yield, and hardness runs Rockwell B95 to C32. That puts it in the range of a corrosion-resistant fastener for equipment, hanger, and support work. For structural steel connections governed by a bolt spec on the drawings, match the designation the engineer called out rather than substituting a stainless cap screw.
4) How many bolts come in a jar of Metallics JSBH171?
They ship 100 to a jar, and 100 count is the order minimum. The jar packaging keeps them together on a van or a parts shelf instead of loose in a bin, which is the reason most MRO and electrical shops buy this format.
5) Does this Metallics stainless bolt meet Buy American or ARRA requirements on a public project?
The JSBH171 is flagged compliant for both Buy American and ARRA, with country of origin listed as China. On a federally funded job, hand both of those to your compliance reviewer before you submit, since the governing clause on your contract decides which one applies.
6) Can I get this 316 stainless hex bolt in a different length or diameter?
Other sizes and quantities in the SBHC and JSBHC hex cap screw series are available on request. The JSBH171 itself is the 5/16-18 by 3-1/2 inch, 100 per jar configuration.
