Metallics JSBH2561 – Frequently Asked Questions
1) What thread size and pitch are the Metallics JSBH2561 hex bolts, and will they take a standard 3/8-16 nut?
These are 3/8-16 bolts: 16 threads per inch with a measured outside diameter of 0.3690 to 0.3750 inch, which is the standard 3/8 inch coarse (UNC) thread. Any standard 3/8-16 nut or tapped 3/8-16 hole will accept them. Usable length is 3-3/4 inches.
2) Are these stainless bolts suitable for outdoor, coastal, or wet locations?
They are 316 stainless steel, the austenitic grade with molybdenum added, which gives better corrosion resistance than 18-8 stainless and holds strength better at elevated temperature. That makes it the grade people reach for on exterior, marine, pool, and chemical-exposure work where 18-8 would start to pit.
3) How strong are these 316 stainless hex bolts? Can I use them on a structural or load-bearing connection?
Published strength is 100,000 to 150,000 psi minimum tensile and 65,000 psi minimum yield, with hardness of Rockwell B95 to C32. That is typical stainless cap-screw territory, well below a hardened Grade 8 steel bolt. Fine for equipment mounting, strut, framing, and general MRO fastening where corrosion resistance is the driver. If your drawing calls out a specific structural bolt grade, match that call-out instead of substituting stainless.
4) Do these Metallics stainless bolts meet Buy American or ARRA requirements for a government job?
No. The JSBH2561 hex bolts are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. If your contract carries a domestic-sourcing clause, these will not satisfy it and you need a domestically produced fastener instead.
5) What wrench or socket size fits the head on these 3/8-16 stainless hex bolts?
The hex head measures 0.551 to 0.562 inch across the flats, so a 9/16 inch wrench or socket is the fit. Head height is 15/64 inch, which matters if you are working under a bracket or in a shallow recess.
6) Should I use 316 stainless or 18-8 stainless hex cap screws for my job?
Both are austenitic stainless and both resist rust in general service. The difference is exposure: 316, which is what the JSBH2561 bolts are made of, carries molybdenum and stands up better to salt air, chlorides, and high temperature. If the fastener lives indoors or in a dry mechanical room, 18-8 is the usual pick. Near the coast, on a rooftop, around pool chemistry, or on anything that gets washed down, go 316.
7) How are the Metallics JSBH2561 bolts packaged, and is there a minimum order?
They ship 50 pieces in a jar, and the order minimum is 50 each, so one jar is the smallest buy. The jar packaging is handy on a service van or a parts crib shelf where loose bolts in a bag get lost.
8) Can I get this 316 stainless hex bolt in a different length or a larger quantity?
Yes. The SBHC and JSBHC family of Metallics stainless hex cap screws runs other diameters, lengths, and pack quantities beyond the 3/8-16 x 3-3/4 jar of 50, available by request. Give the diameter, thread, length, and count you need.
