Metallics G8HC75134 – Frequently Asked Questions

1) What thread size and pitch is the Metallics G8HC75134 hex bolt?
It's a 3/4-10 bolt: 10 threads per inch, coarse thread, with a measured outside diameter of 0.7410 to 0.7500 inch. It will thread into any standard 3/4-10 UNC nut or tapped hole. If your hole is 3/4-16 fine thread, this is not the bolt.
2) How strong is a Grade 8 hex cap screw compared to Grade 5?
The Metallics G8HC75134 is a Grade 8 cap screw rated at 150,000 psi minimum tensile and 130,000 psi minimum yield, with a surface hardness of Rockwell C33-39. That's the step up people take when a Grade 5 won't carry the load, which is why these are common in automotive and fleet work. It's medium carbon steel, AISI 1021-1045, heat treated.
3) What size wrench or socket do I need for this 3/4-10 Grade 8 bolt?
The hex head measures 1.100 to 1.125 inch across the flats, so a 1-1/8 inch socket or wrench is the right fit. Across corners it runs 1.240 to 1.299 inch, which matters if you're checking clearance in a tight bracket or counterbore.
4) Is the Metallics G8HC75134 coated for outdoor or damp use?
The finish is zinc plated steel. Zinc gives basic corrosion resistance for indoor, sheltered, and light-duty exterior work. For continuous weather exposure or wash-down, a hot dip galvanized or stainless fastener is the better call, though stainless will not give you Grade 8 strength.
5) Do these Metallics Grade 8 bolts qualify for a Buy American or ARRA funded project?
No. The G8HC75134 is not Buy American compliant and is not ARRA compliant; country of origin is listed as multiple. If your job carries a domestic-content requirement, you'll need a fastener sourced specifically to that spec.
6) How much head clearance does the Metallics G8HC75134 need above the surface?
Head height runs 0.455 to 0.483 inch, so budget roughly a half inch of stand-off above the joint face for the head plus whatever your socket needs to engage it.
7) How are these Grade 8 hex bolts packaged and what is the minimum order?
They ship in a box of 25, and 25 each is the order minimum. Metallics makes other sizes and quantities of the G8HC series available by request.
8) Can I reuse a Grade 8 bolt after it has been torqued down?
These are heat-treated medium carbon steel cap screws, AISI 1021-1045, hardened to Rockwell C33-39. They are not marked as torque-to-yield, so a bolt that has not been stretched past yield or damaged can normally be re-torqued. Inspect the threads and replace anything galled or necked down; at 130,000 psi minimum yield, a compromised bolt is not worth saving.
