Metallics JSBH19 Bolts 1/2-13 x 5-1/2 HXBT SS (Jar 25)

Yes. The JSBH19 is a 1/2-13 bolt, 13 threads per inch, with a measured shank outside diameter of 0.4930 to 0.5000 inch. That is standard 1/2 inch UNC coarse thread, so it mates with any 1/2-13 nut, coupling, or tapped strut insert. The 5-1/2 inch length under the head is what you have to work with for grip plus nut engagement.

It is 18-8 austenitic stainless, which handles general atmospheric corrosion, wash-down areas, and food and chemical processing environments. That covers most exterior and damp mechanical rooms. Where you have aggressive chemistry, chlorides, or coastal salt exposure, 18-8 is the wrong choice and you want a 316 stainless bolt in the same 1/2-13 x 5-1/2 size instead.

No. The JSBH19 is not Buy American compliant and not ARRA compliant, with multiple countries of origin on the part. On a federally funded or public agency job carrying domestic sourcing language, this bolt will not satisfy the submittal and you need a domestic-certified fastener instead.

The JSBH19 runs 100,000 to 150,000 psi minimum tensile with 65,000 psi minimum yield and a hardness of Rockwell B95 to C32. That puts it in the same tensile neighborhood as a Grade 5 zinc plated bolt, but stainless yields sooner and galls under torque, so do not carry over a Grade 5 or Grade 8 torque spec. If the connection is a structural or high-preload joint, a plated alloy bolt is the better call and you give up the corrosion resistance.

They ship as a jar of 25, and 25 each is the order minimum. There is no single-piece break on this one. Other sizes and quantities in the same hex bolt family are available on request if 5-1/2 inch is longer or shorter than you need.
