Metallics JHTB89 – Frequently Asked Questions
1) What thread size and pitch is the Metallics JHTB89 hex tap bolt?
The JHTB89 is a 5/8-11 bolt, 2 inches long, with right hand threads at 11 threads per inch to IFI-199 (2014). It mates with any standard 5/8-11 UNC nut or tapped hole.
2) Is a hex tap bolt threaded all the way to the head?
Yes, that is the point of a tap bolt instead of a hex cap screw. The JHTB89 is built for complete thread engagement applications, so the full 2 inches of the 5/8-11 shank carries thread. Use it where you need thread right up under the head, such as shallow tapped holes or thin strut and channel. If you need an unthreaded shoulder in a shear joint, a partially threaded hex cap screw is the better pick.
3) Can these zinc plated steel bolts be used outdoors or in a wet location?
The JHTB89 is carbon steel with a zinc finish, which handles dry indoor and protected locations well but will eventually corrode in persistent moisture, washdown, or coastal air. For wet or corrosive environments, step up to the 18-8 stainless version in the same HTB/JHTB/JSHTB hex tap bolt series.
4) What strength grade are the Metallics hex tap bolts, and are they strong enough for structural steel?
Tensile strength is 60,000 psi minimum with a hardness of Rockwell B69 to B100. That is standard low carbon grade bolt territory, fine for hanging conduit, strut, equipment supports, and the mechanical and electrical trades. It is not a Grade 5 or Grade 8 bolt, so if a drawing calls for 120,000 psi structural or high strength fasteners, this is not the part.
5) Do Metallics JHTB89 bolts meet Buy American or ARRA requirements on a federal job?
No. The JHTB89 is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. On a federally funded project with domestic sourcing language, you need a documented domestic fastener instead.
6) What size wrench or socket do I need for a 5/8-11 Metallics hex tap bolt?
Head width across flats runs 0.906 to 0.938 inch, which is a 15/16 inch socket or wrench. Head height is 27/64 inch, so allow for that clearance under a bracket or inside a channel.
7) How many bolts come in a jar of Metallics JHTB89?
Twenty five bolts per jar, and the jar is the order minimum. Other sizes and quantities can be arranged by request.
8) Are these hex tap bolts suitable for HVAC and plumbing hangers, or just electrical work?
Both. The field application covers electrical, plumbing, heating, and air conditioning work, so the same 5/8-11 bolt serves conduit racks, pipe hangers, and equipment mounts. That makes it a reasonable item to standardize on across an MRO stockroom rather than carrying separate trade specific bolts.
