Metallics JHTBG31 – Frequently Asked Questions
1) Is the JHTBG31 hex tap bolt threaded the full length?
Yes. A hex tap bolt is threaded right up to the head, which is what separates it from a hex cap screw with a plain shank. At 5/8-11 by 1-1/2 inches you get usable thread over the entire 1-1/2 inch length, so it pulls tight on thin strut, channel, or plate stacks without needing the grip length to line up.
2) Is this 5/8-11 tap bolt a Grade 5 or Grade 8 bolt?
No. The JHTBG31 is a low carbon grade bolt, rated at 60,000 psi minimum tensile with a hardness of Rockwell B69 to B100. If your drawing calls for a Grade 5 or Grade 8 fastener for a structural or high-torque connection, this is not the bolt. It is specified for general electrical support work, hanging strut, pipe racks, and equipment mounting.
3) What nut and thread pitch do I need to pair with the Metallics JHTBG31?
It is a 5/8-11 bolt, 11 threads per inch, which is standard UNC coarse thread, so any 5/8-11 hex nut or tapped 5/8-11 hole mates with it. The threads are made to IFI-199 (2014). Use a galvanized nut to match the finish and avoid mixing dissimilar coatings in a wet location.
4) Can I use the Metallics JHTBG31 on a federally funded or Buy American job?
Yes. The JHTBG31 hex tap bolt is flagged both ARRA compliant and Buy American compliant in its product data, which is what a government, school, or transit spec writer is looking for on a submittal.
5) What wrench size and socket do I need for the Metallics JHTBG31 5/8-11 hex tap bolt?
The hex head measures 0.906 to 0.938 inch across the flats, so a 15/16 inch socket or wrench is the right fit. Head height is 27/64 inch, which matters if you are working in a tight counterbore or behind a channel flange.
6) Will a 5/8-11 galvanized tap bolt work outdoors or in a damp vault?
The bolt is steel with a galvanized finish, which is the normal choice for exterior, damp, and unheated locations where plain finish would bloom rust. For continuous immersion or heavy chemical exposure, stainless is the better material.
7) I need a different length in 5/8-11 galvanized hex tap bolt. Is that available?
The JHTBG31 covers 5/8-11 by 1-1/2 inch, and other sizes and quantities in the Metallics HTB, JHTB, and JSHTB hex tap bolt series can be had by request. Worth asking about if you need a longer bolt to get through a thicker plate stack or doubled strut.
