Metallics JHTB45 – Frequently Asked Questions

1) Is this hex bolt threaded all the way to the head?
Yes. The JHTB45 is a hex tap bolt, meaning the thread runs full length rather than stopping at a shoulder. Metallics lists it for complete thread engagement applications, which is what you want when you are threading into tapped steel like a strut nut, a panel back, or an equipment mounting boss rather than passing through a clearance hole with a nut on the far side.
2) Will a standard 3/8-16 nut or threaded rod coupling thread onto this bolt?
Yes. It is 16 threads per inch, right hand, cut to the IFI-199 (2014) thread standard, so it mates with any standard 3/8-16 UNC nut, coupling, washer stack or tapped hole. No left-hand or metric surprises.
3) How strong is the Metallics 3/8-16 zinc hex tap bolt?
60,000 psi minimum tensile strength, with a hardness of Rockwell B69 to B100. That is a low-carbon commercial-grade fastener suited to panel mounting, duct hangers, pipe supports and bracket work. For structural steel connections or high-preload joints where the drawing calls out a graded bolt, you want a marked Grade 5 or Grade 8 instead.
4) Does the Metallics JHTB45 meet Buy American or ARRA requirements on a federal job?
No. The JHTB45 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your contract carries a domestic sourcing clause, this bolt will not satisfy it.
5) What wrench or socket size fits the Metallics JHTB45 3/8-16 hex tap bolt?
The hex head measures 0.544 to 0.562 inch across the flats, which is a 9/16 inch wrench or socket. The head stands 0.226 to 0.268 inch tall, so a standard socket clears it without needing a deep well.
6) How many bolts come in a jar, and can I buy fewer?
These ship as a 100 piece jar, and 100 is the order minimum, so a jar is the smallest quantity. That is the practical buy for a service van or an MRO crib where 3/8-16 x 1 gets consumed steadily.
7) Is a zinc plated bolt OK for outdoor or damp locations?
The steel body carries a zinc finish, which handles indoor damp, mechanical rooms and general jobsite exposure. Zinc is a sacrificial coating, not stainless, so for sustained wet exposure, coastal air or chemical environments go with a stainless hex tap bolt. In corrosive areas inspect the coating periodically and swap the bolt once it starts breaking down.
8) How much grip does a 1 inch long 3/8-16 bolt actually give me?
Fastener length is 1 inch measured under the head, and since the thread runs the full length every bit of it is usable engagement. Subtract your material and washer thickness to find how deep it lands in the tapped hole. If you are stacking two pieces of channel plus a washer, a 1 inch bolt gets tight fast, so step up in length rather than accepting two or three threads of bite.
9) What is the part number to reorder the Metallics 3/8-16 x 1 zinc hex tap bolt?
Order Metallics part JHTB45. It sits in the HTB, JHTB and JSHTB hex tap bolt series, where the JHTB prefix indicates the jar-packed steel zinc version. JSHTB is the stainless line and HTB is the bulk steel zinc line, so match the prefix to the finish and pack you want.
