Metallics JHTB94 Bolts 5/8-11 x 3-1/2 Hx Tap Blt St-zn (Jar 25)

Yes. A hex tap bolt is fully threaded, which is why Metallics lists the JHTB94 for complete thread engagement applications. That matters when you are running the bolt into a tapped hole, a threaded channel nut, or a strut insert where you need thread engaged along the whole grip. The thread is 5/8-11 right hand, 11 threads per inch, made to IFI-199 (2014).

The JHTB94 is steel with a zinc finish, which is a general purpose plating for dry interior and sheltered work. For sustained wet exposure, washdown areas, or coastal and corrosive environments, step up to the 18-8 stainless version in the same hex tap bolt family rather than the zinc plated steel.

Tensile strength is 60,000 psi minimum with a hardness of Rockwell B69 to B100. That is standard low carbon steel bolt territory, fine for hanging conduit, strut, equipment supports, and HVAC and plumbing hangers. If your drawing calls out a higher strength fastener for a structural connection, this is not the bolt for it.

No. The JHTB94 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On federally funded or domestic preference projects you will need a domestically sourced fastener instead.

JHTB94 ships as a jar of 25 bolts, and 25 each is the order minimum, so it is a full jar at a time. Metallics does offer other sizes and quantities in the hex tap bolt line by request if 25 of this size does not suit the job.

Metallics lists it for the electrical, plumbing, heating, and air conditioning trades, and for any application calling for complete thread engagement. In practice that is strut and channel work, hanger and support assemblies, equipment and panel mounting, and tapped hole connections in mechanical rooms.
