Metallics JSBH252D – Frequently Asked Questions
1) Is the Metallics JSBH252D hex bolt 316 stainless or 18-8 stainless?
The JSBH252D is 316 stainless steel. The molybdenum in 316 gives it more corrosion resistance than 18-8 and better strength at elevated temperatures, which is why it gets specified for coastal, wash-down, and chemically aggressive locations. If you only need general indoor corrosion resistance, 18-8 is the cheaper austenitic option.
2) What thread size and pitch is the JSBH252D bolt, and will it take a standard 3/8 nut?
It is a 3/8 diameter bolt at 16 threads per inch, with a measured shank outside diameter of 0.3690 to 0.3750 inch. Any 3/8-16 nut or tapped hole will mate with it. Note that 3/8-16 is the UNC coarse series, so it will not thread into a 3/8-24 fine-thread hole.
3) How strong is the Metallics 316 stainless hex bolt compared to a plated steel grade 5?
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 same general tensile band as a medium-carbon plated bolt, but austenitic stainless is not heat treatable to grade 8 levels. You are choosing it for corrosion performance first. For high-tension structural connections, specify a graded steel bolt instead.
4) Does the JSBH252D qualify for Buy American and ARRA jobs?
Yes. The bolt is manufactured in the United States and carries both Buy American and ARRA compliant status, which is what a government, school, or transit submittal package usually requires on fasteners.
5) What wrench or socket size fits the head on this 3/8-16 stainless hex bolt?
Head width across the flats is 0.551 to 0.562 inch, which is a 9/16 inch wrench or socket. Head height is 15/64 inch, so it will sit in a shallow counterbore or under a clamp without much stack-up.
6) How is the JSBH252D packaged and what is the minimum order?
It ships as a jar of 100 pieces, and 100 count is the order minimum. The jar weighs 1905 g. The jar pack is the reason for the JSBHC prefix; the SBHC designation in the same series is the bulk-pack equivalent.
7) Can I use these stainless bolts outdoors and on rooftop electrical equipment?
That is what 316 is for. The molybdenum-bearing austenitic alloy holds up better than 18-8 in salt air, rooftop, and wash-down exposure, and it keeps its strength at elevated temperature. Common uses are strut and channel hardware, enclosure mounting, and grounding or bonding connections where a plated bolt would bloom rust.
8) Do nuts or washers come with the Metallics JSBH252D?
No. The jar contains 100 hex bolts only. Order 3/8-16 nuts and 3/8 flat or lock washers separately, and keep them in 316 stainless as well. Mixing a plated steel nut onto a 316 bolt in a wet location sets up galvanic corrosion at the joint.
