Metallics JG5HC124 – Frequently Asked Questions
1) What thread does the Metallics JG5HC124 hex bolt use, and will it take a standard 5/8-11 nut?
It is a 5/8-11 bolt, 11 threads per inch, which is the standard UNC coarse pitch for 5/8 inch diameter. Any standard 5/8-11 coarse nut or tapped hole will take it. Threads are made to ASME B18.2.1-2012, and the measured body diameter runs 0.6170 to 0.6250 inch.
2) Is a Grade 5 zinc bolt strong enough for mounting a motor to a machine base?
Grade 5 is the common medium carbon, heat treated structural fastener grade and is what Metallics specifies for mounting motors to machinery, plus automotive and truck repair work. It carries 105,000 psi minimum tensile and 105,000 psi minimum yield, with a hardness of Rockwell C19-30. For higher clamp loads than that, step up to a Grade 8 bolt.
3) Does the Metallics JG5HC124 bolt qualify for Buy American and ARRA funded jobs?
Metallics flags this Grade 5 hex bolt as compliant for both Buy American and ARRA requirements. Country of origin is listed as multiple, so if your project documents demand a single named origin on the submittal, confirm the origin marking on the lot you receive.
4) How many bolts come in a jar of Metallics JG5HC124?
They ship 25 pieces to a jar, and 25 each is the order minimum. The filled jar weighs 2808 g.
5) Will the zinc finish on this Grade 5 hex bolt hold up outdoors?
The finish is a zinc chromate plating over steel, which handles indoor and sheltered industrial service and light weather exposure. It is not a hot dip galvanized or stainless fastener, so for continuous outdoor, wet, or coastal exposure you want a galvanized or stainless 5/8-11 bolt instead.
6) Can I get this Grade 5 hex bolt in other lengths or a bulk box instead of a 25 piece jar?
Yes. Metallics offers other sizes and quantities in the G5HC and JG5HC Grade 5 hex bolt series by request, so the same 5/8-11 bolt is available in other lengths and pack quantities beyond the 25 count jar.
7) What steel is this Metallics hex bolt made from?
Medium carbon steel, heat treated, with the material called out to AISI 1008 to 1026. That heat treatment is what gets it to the Grade 5 strength level rather than the lower strength of an untreated Grade 2 bolt.
