Metallics JG5HC16 – Frequently Asked Questions

1) What thread size and length is the Metallics JG5HC16 hex bolt?
The JG5HC16 is a 5/16-18 hex cap screw, 3 inches long. That's a coarse thread at 18 threads per inch, with a shank outside diameter of 0.3065 to 0.3125 inch. It takes a standard 5/16-18 nut or a tapped 5/16-18 hole.
2) Is a Grade 5 bolt strong enough for mounting a motor to a machine base?
That's the job it's built for. Grade 5 means medium carbon steel, heat treated, with 105,000 psi minimum tensile and yield strength and a hardness of Rockwell C19-30. Metallics calls out motor mounting to machinery as the primary use, along with automotive and truck repair. For higher-load structural work you'd step up to Grade 8.
3) Do Metallics JG5HC16 bolts meet Buy American requirements on a federal job?
No. These bolts are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. On a job with domestic sourcing requirements you'll need a domestic Grade 5 bolt instead.
4) What wrench or socket size fits the head on a 5/16-18 Grade 5 hex bolt?
Head width across flats measures 0.489 to 0.500 inch, so a 1/2 inch wrench or socket is the right tool. Head height is 13/64 inch.
5) Can zinc plated hex bolts be used outdoors or in a wet location?
Zinc plating on these steel bolts is a light corrosion coating meant for dry or sheltered service, including indoor electrical, plumbing, and HVAC work. It is not a substitute for hot dip galvanized or stainless in standing water, direct weather exposure, or corrosive atmospheres.
6) How much grip length do I get with a 3 inch Grade 5 bolt?
Overall fastener length is 3 inches measured under the head, which is the figure to use when adding up your material stack plus washers plus enough thread for the nut. The head itself adds 13/64 inch above the surface.
7) Can I get this Grade 5 hex bolt in other lengths or diameters?
Yes. The G5HC and JG5HC series covers other sizes and pack quantities by request; JG5HC16 is the 5/16-18 x 3 inch jar of 100 within it.
