Metallics JBHC21 – Frequently Asked Questions
1) What thread does the Metallics JBHC21 hex bolt take, and will a standard 5/8 nut fit it?
The JBHC21 is a 5/8-11 hex bolt, meaning 11 threads per inch, which is the standard coarse (UNC) pitch for 5/8 inch diameter. Any 5/8-11 coarse nut or tapped hole will thread onto it. Thread form follows ASME B18.2.1-1996. Measured shank outside diameter runs 0.605 to 0.642 in.
2) How thick a material can I clamp with a 5/8-11 x 1 inch hex bolt?
Usable grip is short. The JBHC21 has a 1 inch length measured under the head, so once you allow for a nut and washer you are realistically clamping about half an inch of material, or threading into a tapped hole or channel nut. For strut, beam clamps, and bolting into threaded inserts it works well. For stacking two pieces of angle or heavier built-up steel you want a longer 5/8-11 bolt.
3) Does this bolt meet Buy American or ARRA requirements for a federal or public project?
No. The JBHC21 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your contract carries domestic sourcing language, this bolt will not satisfy it and you need a domestically produced 5/8-11 hex bolt.
4) What size wrench or socket do I need for this Metallics hex bolt?
Across the flats the head measures 0.906 to 0.938 in., so a 15/16 inch wrench or socket is the fit. Head height is 27/64 in., which matters if you are working in a shallow recess or next to an obstruction.
5) Can zinc plated hex bolts be used outdoors or in a wet mechanical room?
Zinc plated steel gives light corrosion resistance, so it holds up indoors, in mechanical and electrical rooms, and in covered or dry exterior locations. For direct weather exposure, roof-mounted equipment, or anything washed down or near chemicals, step up to hot dip galvanized or stainless 5/8-11 hardware instead.
6) How many bolts come in a jar, and is there a minimum order?
The JBHC21 ships as a jar of 50 bolts, and 50 each is the order minimum. The jar is the unit you buy, which is handy for a van or a shop crib since loose 5/8 hardware is the first thing to go missing. Other sizes and quantities can be requested.
7) Is the JBHC21 fully threaded, and does it come with nuts or washers?
The JBHC21 is sold as bolts only, 50 to a jar. No nuts or washers are included, so order 5/8-11 nuts and 5/8 washers separately to complete the assembly. Head type is a standard hex, driven with a wrench rather than a driver bit.
8) Are these hex bolts meant for electrical work specifically, or are they general purpose?
They are general purpose steel hex bolts stocked for the electrical, plumbing, and HVAC trades. Nothing about the bolt is electrical-specific, so the same jar covers conduit support brackets, equipment feet, pipe hangers, and air handler mounting.
9) How much does a jar of 50 of these 5/8-11 bolts weigh for shipping?
A jar of 50 comes in at 7.79 lbs. Jar dimensions are listed as 7.25 in height with 4.5 in length and width, which is worth knowing if you are planning shelf or gang box space for a standardized fastener stock.
