Metallics JSBH304 – Frequently Asked Questions
1) Is the Metallics JSBH304 hex bolt a coarse or fine thread, and will it match a standard 5/16-18 nut?
It's a fine thread: 5/16-24, with 24 threads per inch. That means it will not thread into a 5/16-18 coarse nut or a coarse-tapped hole. You need 5/16-24 UNF nuts or UNF-tapped threads. Shank diameter runs 0.3065 to 0.3125 in., which is standard for 5/16 in.
2) Will 18-8 stainless hex bolts hold up outdoors or in a food processing plant?
18-8 stainless is what these are made from, and it's used where general atmospheric corrosion resistance is needed, including chemical and food processing equipment. For aggressive chemical exposure, 316 stainless or another specialty alloy is the better call rather than 18-8.
3) What wrench or socket size fits the head on this 5/16-24 stainless hex bolt?
Head width across flats measures 0.489 to 0.500 in., so a 1/2 in. wrench or socket is the fit. Head height is 13/64 in., worth knowing if you're working in a tight counterbore or under a bracket.
4) How strong are these stainless bolts compared with a plated steel grade 5?
Tensile runs 100,000 to 150,000 psi minimum with a 65,000 psi minimum yield, and hardness is Rockwell B95 to C32. That puts them below a Grade 5 plated steel bolt on yield, so where load is the governing factor and corrosion isn't, plated steel is the stronger choice. Stainless earns its place where the fastener has to resist corrosion.
5) How many bolts come in a jar of Metallics JSBH304, and is there an order minimum?
They ship as a jar of 100, and the order minimum is 100 count. Other sizes and quantities can be requested if 5/16-24 x 2 in. isn't the length you need.
6) How much grip length do I get from a 2 inch 5/16-24 hex bolt?
Overall fastener length is 2 in. measured below the head, which is the figure to work from when you add up your material thickness, washers, and nut. The head itself adds 13/64 in. above the surface.
7) Do these Metallics hex bolts qualify for Buy American or ARRA funded work?
Both the Buy American and ARRA compliance flags on the JSBH304 read compliant. Country of origin is listed as multiple, so if your contract requires documented origin for a specific lot, that is the detail to pin down with the paperwork.
8) Are nuts and washers included with the JSBH304 jar?
No. The jar contains 100 hex bolts only. You'll need to order 5/16-24 fine thread nuts and any flat or lock washers separately, and matching them in 18-8 stainless keeps you from setting up galvanic corrosion at the joint.
