Metallics JG5HC37 – Frequently Asked Questions
1) What thread and size is the Metallics JG5HC37 hex bolt, and what wrench does it take?
It is a 1/2-13 bolt, 4 inches long, with a hex head. Thread pitch is 13 threads per inch (UNC coarse), and the shank measures 0.4930 to 0.5000 inch across. Head width across flats runs 0.736 to 0.750 inch, so a 3/4 inch wrench or socket fits it.
2) Is a Grade 5 zinc bolt strong enough for mounting a motor or hanging equipment?
Grade 5 is the standard medium carbon, heat treated choice for that work. The JG5HC37 carries a 105,000 psi minimum tensile strength and hardness of Rockwell C19-30, made from AISI 1008-1026 steel. Metallics lists motor mounting to machinery as a primary use, along with automotive and truck repair. For higher-stress structural connections a Grade 8 bolt would be the step up.
3) Does the Metallics JG5HC37 hex bolt meet Buy American or ARRA requirements for a public project?
No. The JG5HC37 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded job with domestic sourcing language, you need a domestic Grade 5 hex bolt instead.
4) How many bolts come in a jar of Metallics JG5HC37, and can I buy fewer?
They ship in a jar of 25, and 25 each is the order minimum, so a single jar is the smallest buy. The filled jar weighs about 2694 g. Other sizes and quantities are available by request.
5) What dimensional standard do these Grade 5 hex bolts follow, and will they fit standard tooling and holes?
The threads and head geometry follow ASME B18.2.1-2012, the standard for inch hex bolts and cap screws. That means the 3/4 inch head flats, 1/2-13 UNC thread, and shank diameter all match any other standards-compliant 1/2 inch hex bolt, so it drops into a standard 9/16 inch clearance hole and takes any 1/2-13 nut.
6) Do I need to order nuts and washers separately with these bolts?
Yes. The jar contains 25 hex bolts only, nothing else. For a through-bolted connection you add 1/2-13 hex nuts and 1/2 inch flat or lock washers, and matching the zinc plating on those keeps dissimilar metal corrosion out of the joint.
7) How much head clearance do I need above a 1/2 inch Grade 5 hex bolt?
Wrenching height on the JG5HC37 is 0.215 inch, which is the minimum full-strength bearing surface a socket can grip. Plan for at least that much clear depth around the head plus socket wall thickness, so a counterbore or recess tight to the head will keep a standard socket from seating.
