Metallics JG8HC2 – Frequently Asked Questions

1) What size and thread pitch is the Metallics JG8HC2 Grade 8 hex bolt?
It's a 1/4-20 hex cap screw, 1 inch long, with 20 threads per inch (standard UNC coarse thread for 1/4 inch). Measured shank outside diameter runs 0.2450 to 0.2500 inch. So it mates with any standard 1/4-20 nut or tapped hole.
2) How strong is a Grade 8 bolt compared to a Grade 5 for high-load fleet and equipment work?
The JG8HC2 is Grade 8: 150,000 psi minimum tensile and 130,000 psi minimum yield, hardness Rockwell C33-39. That's the step up you take when a Grade 5 won't carry the load, which is why it gets used in automotive and fleet work. It's medium carbon steel, heat treated, per AISI 1021-1045.
3) Do these Metallics bolts meet Buy American or ARRA requirements on a federal job?
No. The JG8HC2 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your contract carries domestic sourcing language, this part won't satisfy it.
4) What wrench or socket size fits this 1/4-20 Grade 8 hex bolt head?
Head width across flats measures 0.428 to 0.438 inch, which takes a 7/16 inch wrench or socket. Across corners the head runs 0.484 to 0.505 inch, worth checking if you're torquing in a tight pocket or counterbore.
5) Is the zinc finish on these Grade 8 bolts good enough for outdoor or damp locations?
The JG8HC2 is steel with a zinc finish. Zinc plating handles indoor and sheltered exterior service, but it is a coating over carbon steel, not stainless. For continuous wet, coastal, or chemical exposure, stainless or hot-dip galvanized hardware is the better call, keeping in mind stainless won't match Grade 8 strength.
6) How are these 1/4-20 Grade 8 bolts packaged and what is the minimum order?
They ship in a jar of 100 pieces, and the jar is the order unit, so 100 is the minimum. Jar weight is listed at 789 g. For a service truck or shop bin, one jar covers a lot of 1/4-20 work; other sizes and quantities can be requested.
7) Does this bolt come with a nut or washer?
No, the JG8HC2 jar holds hex cap screws only, 100 of them. Order 1/4-20 nuts and flat or lock washers separately, and match them to Grade 8 strength so the nut isn't the weak point in the joint.
8) Are Grade 8 hex bolts appropriate for electrical, HVAC and plumbing equipment mounting?
Yes, that's the stated field application for the G8HC and JG8HC series: electrical, plumbing, heating and air conditioning work. A 1/4-20 x 1 Grade 8 hex cap screw suits equipment mounting, strut and bracket connections, and anywhere a Grade 5 fastener is being pulled past its limit.
