Metallics JG5HC34 – Frequently Asked Questions
1) What thread does the Metallics JG5HC34 hex bolt take, and will a standard 1/2-13 nut fit it?
The JG5HC34 is a 1/2-13 bolt, 13 threads per inch, which is standard UNC coarse thread for 1/2 inch diameter. Any standard 1/2-13 UNC nut or tapped hole will take it. Shank diameter measures 0.4930 to 0.5000 inch, and the threads are made to ASME B18.2.1-2012.
2) Is a Grade 5 hex bolt strong enough for mounting a motor to a machine base?
Yes, and that is the intended use for the Metallics JG5HC34. It is a medium carbon steel cap screw, heat treated to Rockwell C19-30, with 105,000 psi minimum tensile strength. Grade 5 is the normal choice for motor mounts, equipment bases, and automotive and truck repair work.
3) How much material can a 1/2-13 x 2-1/2 inch hex bolt clamp through?
Overall shank length is 2-1/2 inches, so your total grip, the combined thickness of the parts plus any washers, needs to leave enough thread for the nut to fully engage. On a through bolted joint plan on roughly 2 inches of material or less with a nut and two washers. For thicker stacks, order a longer length from the same G5HC and JG5HC series.
4) Can I use these Metallics hex bolts on a federally funded or Buy American job?
No. The JG5HC34 is not Buy American compliant and not ARRA compliant, and country of origin is listed as multiple. If your contract carries a domestic sourcing clause, you need a documented domestic Grade 5 bolt instead.
5) What size wrench or socket do I need for the Metallics JG5HC34 bolt head?
Across the flats the hex head measures 0.736 to 0.750 inch, so a 3/4 inch wrench or socket is the right tool. Corner to corner the head runs 0.840 to 0.866 inch, which matters if you are working in a tight pocket or counterbore.
6) Are these zinc plated bolts okay for outdoor or wet locations?
The JG5HC34 is steel with a zinc finish, which handles indoor and sheltered mechanical work, light moisture, and general MRO duty. For sustained outdoor exposure, washdown areas, or coastal sites, step up to hot dip galvanized or stainless, since zinc plating is a thin sacrificial coating rather than a marine grade one.
7) How many bolts come in the Metallics JG5HC34 jar?
Fifty 1/2-13 x 2-1/2 inch Grade 5 hex bolts, packed in a jar, with an order minimum of 50 each. The jar as packed weighs 3679 g. Other sizes and quantities in the G5HC and JG5HC series are available on request.
8) Is this hex bolt suitable for electrical and HVAC trade work, or is it a general hardware bolt?
Both. Metallics catalogs the JG5HC34 for the electrical, plumbing, heating and air conditioning trades, and the same bolt is used for motor mounting and automotive or truck repair. It is a general purpose Grade 5 hex cap screw, not a trade specific part.
9) What steel are Metallics Grade 5 hex bolts made from?
The stock conforms to AISI 1008 through 1026, a medium carbon steel that is heat treated after forming. The result is Rockwell C19-30 hardness with 105,000 psi minimum tensile and yield values, which is what distinguishes it from an untreated Grade 2 bolt of the same size.
