Metallics JG8HC76134 – Frequently Asked Questions

1) Is the Metallics JG8HC76134 hex bolt coarse or fine thread?
Coarse. The Metallics JG8HC76134 is a 7/16-14 bolt, meaning 14 threads per inch, which is the UNC coarse pitch for 7/16 inch diameter. If your nut or tapped hole is 7/16-20, this bolt will not thread into it.
2) How much stronger is a Grade 8 bolt than a Grade 5 for a fleet repair?
Grade 8 is the step up when a Grade 5 will not hold. The JG8HC76134 is rated at 150,000 psi minimum tensile and 130,000 psi minimum yield, with a hardness of Rockwell C33-39. It is a medium carbon steel cap screw, heat treated, and gets used in automotive and fleet work where Grade 5 tensile strength is not enough.
3) Does this Metallics hex bolt meet Buy American or ARRA requirements on a federal job?
No. The JG8HC76134 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your contract carries a domestic sourcing clause, this bolt will not satisfy it.
4) What wrench or socket size fits this Grade 8 hex bolt?
The hex head measures 0.612 to 0.625 inch across the flats, so a 5/8 inch socket or wrench is the fit. Head height is 19/64 inch, which matters if you are working in a shallow counterbore or under a bracket.
5) How is this Metallics bolt packaged and what is the minimum I can buy?
It ships in a jar of 100, and 100 count is the order minimum. That is a shop or service truck quantity rather than a bulk box. Metallics does offer other sizes and quantities in the G8HC and JG8HC series by request.
6) What grade nut should I pair with a Grade 8 bolt?
Match the nut to the bolt. A Grade 8 bolt at 150,000 psi minimum tensile should be run with a Grade 8 (or Grade C) nut in 7/16-14; a lower grade nut strips before the bolt reaches its rated load, so the extra bolt strength does nothing for you. Hardened washers under the head and nut are standard practice on Grade 8 joints.
7) Is a zinc plated Grade 8 bolt OK for outdoor or wash-down use?
The bolt is steel with a zinc finish, which gives moderate corrosion protection for general indoor, under-hood, and sheltered outdoor work. It is not stainless. For constant salt spray, marine exposure, or chemical wash-down, zinc plated carbon steel will eventually rust at the threads and exposed head.
8) What steel is this Grade 8 cap screw made from?
Material standard is AISI 1021 to 1045, a medium carbon steel, heat treated to reach Grade 8 properties at Rockwell C33-39. That heat treatment is also why you should not weld on or re-heat a Grade 8 bolt; it loses the strength you bought it for.
