Metallics JSBH23D Bolts 3/8-16 X 1-1/2 Hxbt SS (Jar 100)

It's a 3/8-16 thread, 16 threads per inch, with a measured outside diameter of 0.3690 to 0.3750 inch. Any standard 3/8-16 UNC nut or tapped hole will take it. Don't confuse it with 3/8-24 fine thread, which will cross-thread and gall, especially in stainless.

The bolt is 18-8 stainless steel, an austenitic alloy used where general atmospheric corrosion resistance is needed, including chemical and food-processing equipment. For outdoor and wash-down work that's the usual choice. Aggressive chemical exposure, chlorides or marine salt spray is where 18-8 falls short and 316 stainless is the move.

No. The JSBH23D is flagged as not Buy American compliant and not ARRA compliant, even though country of origin is listed as the United States. If your contract carries a domestic preference clause, this part number won't satisfy the submittal.

The JSBH23D carries a tensile strength of 100,000 to 150,000 psi minimum and a yield of 65,000 psi minimum, with hardness in the Rockwell B95 to C32 range. That puts it in the neighborhood of a Grade 5 steel bolt on tensile but with a notably lower yield, so stainless stretches sooner under load. If the connection is structural and highly loaded, spec a graded carbon steel bolt and handle corrosion with coating instead.

Bolts only, 100 pieces packed in a jar. Nuts, flat washers and lock washers are separate line items, and for stainless work you want them in stainless too, since mixing stainless bolts with plated steel nuts sets up galvanic corrosion at the joint.

It ships as a jar of 100 pieces, and 100 count is the order minimum, so the jar is the smallest unit. Metallics does offer other sizes and quantities in the SBHC and JSBHC hex bolt series by request if 100 of this length isn't what the job needs.
