Metallics JG5HC1 – Frequently Asked Questions
1) What thread and size is the Metallics JG5HC1 hex bolt?
The JG5HC1 is a 1/4-20 x 3/4 inch hex bolt: 20 threads per inch on a coarse 1/4 inch shank, with a measured outside diameter of 0.2450 to 0.2500 inch. Threads are cut to ASME B18.2.1-2012, so it mates with any standard 1/4-20 nut or tapped hole.
2) Is a Grade 5 bolt strong enough for mounting a motor to machinery?
Yes, that is the intended use. The JG5HC1 is a Grade 5 cap screw in medium carbon steel, heat treated to Rockwell C25-34, rated 120,000 psi minimum tensile and 92,000 psi minimum yield. Metallics lists motor-to-machinery mounting as its primary application, along with automotive and truck repair.
3) Does this Metallics bolt meet Buy American or ARRA requirements for a government job?
No. The JG5HC1 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your spec carries a domestic sourcing clause, this jar will not satisfy it.
4) What size wrench or socket fits the head on this 1/4-20 Grade 5 hex bolt?
The hex head measures 0.428 to 0.438 inch across the flats, which is a 7/16 inch wrench or socket. That is the standard head size on a 1/4-20 hex bolt.
5) How many bolts come in a jar of Metallics JG5HC1, and can I buy fewer?
They ship as a jar of 100. The order minimum is one jar, so 100 pieces is the smallest quantity. Metallics notes other sizes and quantities are available by request.
6) Will a zinc plated Grade 5 bolt hold up outdoors or in a damp mechanical room?
The JG5HC1 is steel with a zinc plated finish, which handles indoor and sheltered mechanical, plumbing, and HVAC work. Zinc plating is a light sacrificial coating, not hot dip galvanizing or stainless, so for direct weather exposure, wet locations, or coastal air you want a hot dip galvanized or stainless 1/4-20 bolt instead.
7) What steel is used in the Metallics G5HC series hex bolts?
Medium carbon steel in the AISI 1008-1026 range, heat treated to reach Grade 5 properties. That is what gets it to Rockwell C25-34 hardness and 120,000 psi tensile, versus a plain unhardened Grade 2 bolt of the same size.
