Metallics JSBH771 – Frequently Asked Questions
1) Is the JSBH771 bolt 316 stainless or 18-8?
It is 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, chemical, and wastewater work rather than plain dry interior fastening.
2) Does this Metallics hex bolt meet Buy American and ARRA requirements for a federal job?
The JSBH771 is flagged compliant for both Buy American and ARRA, which is what a government or institutional procurement package usually asks for on fasteners.
3) How strong is a 316 stainless hex bolt compared to a plated grade 5?
The JSBH771 carries a minimum tensile of 100,000 to 150,000 psi and a minimum yield of 65,000 psi, with hardness Rockwell B95 to C32. That is below a Grade 5 carbon steel bolt on raw strength, which is the trade-off you make for 316's corrosion performance. On structural connections where load governs rather than environment, a carbon steel grade bolt is the right call.
4) How many bolts come in the JSBH771 jar?
Fifty bolts, packed in a jar. The order minimum is 50 each, so a jar is the smallest quantity you buy. Net weight of the packed jar is 3,411 g.
5) Do nuts and washers come with the Metallics JSBH771 bolts?
No. The jar contains the hex bolts only. You order 3/8-16 nuts and 3/8 flat and lock washers separately, and on a 316 job they should be 316 stainless too, otherwise the dissimilar metal at the joint becomes the corrosion point you were trying to avoid.
6) Can I get this Metallics hex bolt in other lengths or pack sizes?
Yes. The SBHC and JSBHC series covers other sizes and quantities by request, so if you need the same 316 stainless hex bolt in a different length or a bulk box instead of a 50-count jar, it can be quoted.
