Metallics JSHTB45 Bolts 3/8-16 X 1 Hx Tap Blt SS (Jar 100)

It's a 3/8-16 bolt: 3/8 inch diameter with 16 threads per inch, right-hand thread, cut to the IFI-199 (2014) thread standard. That's the standard UNC coarse pitch for 3/8 inch, so it threads into any 3/8-16 tapped hole, strut channel nut, or coarse hex nut. Overall length is 1 inch.

They're 18-8 stainless steel, the common 300-series grade used where corrosion is the concern, so wet rooms, exterior strut runs, rooftop equipment and coastal-adjacent work are all normal uses. 18-8 is non-magnetic in the annealed condition and won't rust-bleed the way zinc-plated carbon steel does once the plating is scratched.

The JSHTB45 is rated 95,000 psi minimum tensile and 60,000 psi minimum yield, with hardness Rockwell B95 to C32. That's below a Grade 5 carbon steel bolt on strength, so if the connection is a structural or high-torque one, stainless is the wrong trade: you buy 18-8 for corrosion resistance, not for load. For plain dry interior structural bolting, a zinc-plated Grade 5 hex bolt is the stronger choice.

No. The JSHTB45 hex tap bolt is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your spec carries a domestic-sourcing clause, this part won't satisfy it.

Head width across the flats runs 0.544 to 0.562 inch, which is a 9/16 inch wrench or socket. Across the corners the head measures 0.620 to 0.650 inch, so figure on that much clearance around the head when you're working in a tight channel or next to a flange.

They ship as a jar of 100, and the jar is the order minimum, so 100 pieces is the smallest quantity. The jar pack is what service vans and MRO stockrooms want: one container per size on the shelf instead of loose bulk. Other sizes and quantities can be had by request.
