Metallics JG5HC30 – Frequently Asked Questions
1) What thread and size is the Metallics JG5HC30 hex bolt, and will a standard 3/8-16 nut thread onto it?
The JG5HC30 is a 3/8-16 x 1-3/4 inch hex cap screw, so 16 threads per inch on a 3/8 inch coarse (UNC) thread. Any standard 3/8-16 UNC nut or tapped hole takes it. Shank outside diameter runs 0.3690 to 0.3750 inch and the threads are made to ASME B18.2.1-2012, the dimensional standard for square and hex bolts and screws, so it mates with off-the-shelf 3/8-16 hardware.
2) Is a Grade 5 bolt strong enough for mounting a motor to a machine base?
Yes, and that is the intended use for the JG5HC30. It is a medium carbon steel cap screw, heat treated to Rockwell C19-30, with 105,000 psi minimum tensile and yield strength. Grade 5 is the normal choice for motor mounts, machinery bases, and automotive or truck repair work. For a joint that calls out Grade 8 on the drawing, Grade 5 is not a substitute.
3) How many bolts come in a jar, and can I buy fewer than a full jar?
These ship as a jar of 100 pieces, and 100 count is the order minimum, so the jar is the smallest unit. The full jar weighs 2776 g. Metallics offers other sizes and quantities in the G5HC and JG5HC series on request.
4) Will a zinc plated Grade 5 bolt hold up outdoors or in a damp mechanical room?
The JG5HC30 is zinc plated steel, which handles indoor mechanical rooms, equipment rooms, and sheltered outdoor work. Zinc is a sacrificial coating, not stainless, so continuous wet exposure, coastal salt air, or chemical washdown will eventually corrode it. For those conditions specify stainless or hot dip galvanized instead.
5) Do these Metallics hex bolts meet Buy American and ARRA requirements for a federal or public project?
Metallics lists the JG5HC30 as both Buy American compliant and ARRA compliant, which is what a government, school, or healthcare procurement file usually needs on fasteners. Country of origin is recorded as multiple.
6) How much material thickness can a 1-3/4 inch long 3/8-16 bolt clamp?
At 1-3/4 inch overall length under the head, grip is whatever is left after the nut and washers. A hex cap screw this length is partially threaded, so plan the stack so the plain shank or at least full thread engagement lands in the nut. For thicker assemblies step up in length within the same G5HC and JG5HC Grade 5 line rather than stacking washers to make up the difference.
7) What steel are Metallics Grade 5 hex cap screws made from?
Material is carbon steel in the AISI 1008 to 1026 range, heat treated to reach Grade 5 properties at Rockwell C19-30. That is a medium carbon heat treated cap screw, not a plain unhardened bolt, which is why it holds 105,000 psi minimum tensile.
