Metallics JSBH183 – Frequently Asked Questions
1) What thread size and pitch is the Metallics JSBH183 hex bolt, and what nut do I need for it?
It's a 1 inch diameter bolt with 8 threads per inch, which is the standard UNC coarse pitch for 1 inch. Measured shank diameter runs 0.9900 to 1.0000 inch. Pair it with a 1-8 UNC heavy or finished hex nut; nuts are not included with the jar.
2) Is 18-8 stainless the right bolt for a coastal or chlorinated environment, or do I need 316?
The JSBH183 is 18-8 stainless, an austenitic alloy suited to general atmospheric corrosion resistance, the kind of duty you see on chemical and food-processing equipment. For salt spray, chlorides, or aggressive chemical exposure, 316 stainless is the better choice in the same hex bolt family. Metallics builds both 18-8 and 316 versions of these cap screws.
3) How strong is this stainless bolt compared to a plain steel grade 5?
Tensile runs 85,000 to 140,000 psi minimum with a 45,000 psi minimum yield, and hardness is Rockwell B80 to C32. That puts it in the range of an SAE Grade 5 for tensile but with a notably lower yield, so it is not a drop-in substitute where a structural bolt was specified by grade. You buy 18-8 here for corrosion resistance, not for maximum strength.
4) What wrench or socket size fits these 1-8 stainless hex bolts?
Across the flats the hex head measures 1.469 to 1.500 inch, so a 1-1/2 inch wrench or socket is the fit. Head height is 39/64 inch, which matters if you're working in a counterbored or tight-clearance pocket.
5) What grip length do these 4 inch bolts give me, and will they work on a thick assembly?
Length is 4 inches, measured under the head as hex bolts always are, so the head height of 39/64 inch is on top of that. On a 1-8 bolt this length is partially threaded, so plan your stack-up and nut engagement around the usable thread at the end rather than assuming full-length thread.
6) How many bolts come in a jar, and can I order fewer than 25?
These ship 25 to a jar, and 25 each is the order minimum, so a jar is the smallest buy. Other sizes and quantities in the same hex bolt family are available by request.
7) Do these Metallics stainless hex bolts qualify for a Buy American or ARRA-funded job?
Both the ARRA and Buy American compliance flags on the JSBH183 are marked C for compliant. Country of origin is listed as multiple, which is normal on a compliant fastener line where production runs across more than one plant. If your specifier needs mill documentation for a federally funded project, request it with the order.
