Metallics JG5HC63 – Frequently Asked Questions
1) What thread and size is the Metallics JG5HC63 hex bolt, and what wrench does it take?
It's a 5/8-11 bolt, 2 inches long, with 11 threads per inch on a coarse UNC pitch. The shank measures 0.6170 to 0.6250 inch outside diameter and the hex head measures 0.922 to 0.938 inch across the flats, so a 15/16 inch wrench or socket fits it. Head height is 25/64 inch. Threads are made to ASME B18.2.1-2012.
2) Is a Grade 5 hex bolt strong enough to mount a motor to a machine base?
Yes, that's the job this one is made for. The JG5HC63 is a Grade 5 cap screw in medium carbon steel, heat treated to Rockwell C19-30, with 105,000 psi minimum tensile and 105,000 psi minimum yield. It's commonly used to mount motors to machinery and in automotive and truck repair. If your drawing calls out Grade 8 or a stainless fastener, Grade 5 is not a substitute.
3) Will these Metallics Grade 5 bolts meet a Buy American or ARRA requirement on a federal job?
No. The JG5HC63 is not Buy American compliant and is not ARRA compliant; country of origin is listed as multiple. If your contract carries a domestic sourcing clause, you need a domestically produced fastener instead.
4) Can these zinc plated Grade 5 bolts be used outdoors or in a wet location?
The bolt is plain steel with a zinc finish, which handles indoor and sheltered mechanical work but is not a marine or continuously wet material. For rooftop equipment, washdown areas, or corrosive atmospheres, specify hot dip galvanized or stainless instead.
5) What nut do I pair with the Metallics JG5HC63?
Any 5/8-11 coarse thread nut mates with it, since the bolt is cut to 11 threads per inch under ASME B18.2.1-2012. Match the nut grade to the bolt so you don't under-rate the joint, and pick a zinc plated nut and washer to keep the finishes consistent.
6) How are these bolts packaged, and what is the minimum I can buy?
They ship in a jar of 50, and 50 each is the order minimum. The jar itself is a handy size for a service van or a shop bin rather than a bulk carton.
7) What trades use a 5/8-11 Grade 5 hex cap screw like this?
Metallics lists it for electrical, plumbing, heating and air conditioning work. In practice that means equipment and motor mounting, hanging and anchoring gear, and general machinery fastening, plus automotive and truck repair. The hex head means it's driven with a wrench or socket, not a driver bit.
8) What steel are these bolts made from?
Medium carbon steel to AISI 1008-1026, heat treated to reach Grade 5 properties at Rockwell C19-30. That heat treatment is why a Grade 5 holds 105,000 psi minimum tensile where an unhardened Grade 2 bolt of the same size would not.
