Metallics JSBH435 Bolts 5/16-18 X 1 Hxbt SS (Jar 100)

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, pool chemical, and rooftop work rather than plain indoor fastening.

Tensile runs 100,000 to 150,000 psi minimum with a 65,000 psi minimum yield, and hardness is Rockwell B95 to C32. That is service-grade strength for equipment mounting, strut, hangers, and enclosure work. Stainless is not a substitute for a structural bolt where the drawing calls out a specific structural grade, so match what the engineer specified on load-bearing steel.

No. The JSBH435 hex bolt 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'll need a domestic-origin fastener instead.

Head width across flats measures 0.489 to 0.500 inch, so a 1/2 inch wrench or socket is the right fit. Head height is 13/64 inch, which matters if you are working in a tight channel or under a strut where head stack-up is limited.

100 pieces per jar, and the jar is the order minimum unit. Total weight is 1293 g. If you need a different size or a different count, Metallics offers other sizes and quantities in the SBHC and JSBHC hex bolt series on request.

No. The jar holds 100 hex bolts only, 5/16-18 by 1 inch. Order 5/16-18 nuts and 5/16 washers separately, and match them in 316 stainless so you don't set up galvanic corrosion against the bolt in a wet or coastal location.

Metallics lists this bolt for the electrical, plumbing, heating and air conditioning trades. In practice that means strut and channel assemblies, pipe and duct hangers, enclosure and panel mounting, and rooftop mechanical anchoring where a plated bolt would rust out.
