Metallics JSBH43 – Frequently Asked Questions
1) What size and thread is the Metallics JSBH43 hex bolt?
The JSBH43 is a 5/16-18 hex bolt, 1 inch long. Thread count is 18 threads per inch, which is the coarse (UNC) pitch for 5/16 diameter, so it mates with standard 5/16-18 nuts and tapped holes. Measured shank outside diameter runs 0.3065 to 0.3125 inch.
2) Will stainless hex bolts hold up outdoors or in a wash-down area?
These are 18-8 stainless, an austenitic alloy used where general atmospheric corrosion resistance is needed, including chemical and food-processing equipment. That covers exterior mounting, damp mechanical rooms and wash-down environments. Aggressive chemical exposure or chloride-heavy coastal service may call for 316 stainless or other special corrosion-resistant material instead.
3) Are these bolts Buy American or ARRA compliant for a government or public project?
No. The JSBH43 hex bolts are not Buy American compliant and are not ARRA compliant. Country of origin is listed as multiple. If your contract carries a domestic-content clause, these will not satisfy it.
4) What wrench or socket size fits these 5/16-18 stainless hex bolts?
Head width across flats measures 0.489 to 0.500 inch, so a 1/2 inch wrench or socket is the right size. Head height is 13/64 inch, worth knowing if you are working in a shallow recess or under a channel strut.
5) How many bolts come in a jar, and can I buy fewer than a full jar?
The JSBH43 ships as a jar of 100, and 100 pieces in jar units is the order minimum, so a full jar is the smallest purchase. Metallics also offers other sizes and quantities by request if a 100-count jar of 5/16-18 x 1 is not the pack you need.
6) Do nuts or washers come with the Metallics JSBH43 bolts?
The jar contains hex bolts only, 100 pieces of 5/16-18 x 1. Nuts, flat washers and lock washers are separate items, so order 5/16-18 stainless nuts and matching 5/16 washers alongside if the connection is not into a tapped hole.
7) Will a 1 inch long bolt be long enough for my assembly?
At 1 inch of overall bolt length you need the combined thickness of your clamped parts, plus any washers, to come in under that so the thread still engages the nut fully. For 5/16-18, allow roughly a diameter of thread engagement. If your stack-up is thicker, step up to a longer 5/16-18 stainless hex bolt; Metallics offers other lengths by request.
8) What trades use the Metallics 5/16-18 stainless hex bolt?
Metallics lists these for the electrical, plumbing, heating and air conditioning trades. Typical use is fastening strut, hangers, brackets, enclosures and equipment where a stainless fastener is wanted for corrosion resistance rather than high structural load.
9) Can I mix these stainless bolts with galvanized strut or zinc-plated nuts?
Mechanically yes, any 5/16-18 nut threads on. Just be aware that pairing 18-8 stainless with zinc or galvanized hardware in a wet location sets up dissimilar-metal corrosion that eats the coated part first. If you chose stainless for the corrosion resistance, keep the nuts and washers stainless too.
