Metallics G5HC80 – Frequently Asked Questions
1) What thread and size is the Metallics G5HC80 hex bolt, and what nut will it take?
The G5HC80 is a 3/4-10 hex bolt, 3 inches long. That's 10 threads per inch on a 3/4 inch coarse (UNC) thread, with a measured shank diameter of 0.7410 to 0.7500 inch, so it mates with any standard 3/4-10 UNC nut or tapped hole. Threads are made to ASME B18.2.1-2012.
2) Is a Grade 5 bolt strong enough for mounting a motor to machinery?
That's the job it's built for. The G5HC80 is medium carbon steel, heat treated, with 105,000 psi minimum tensile and yield strength and a hardness of Rockwell C19-30. Metallics calls out motor-to-machinery mounting as its primary use, along with automotive and truck repair. If your drawing calls for Grade 8 or stainless, this is not a substitute.
3) Does the Metallics G5HC80 hex bolt qualify for Buy American or ARRA funded jobs?
It's flagged compliant for both Buy American and ARRA on government and federally funded work. Country of origin is listed as multiple, so if your project requires documented domestic melt and manufacture on each lot, request the certification for the specific lot shipped.
4) What size wrench or socket do I need for this 3/4-10 Grade 5 hex bolt?
Across the flats the hex head measures 1.100 to 1.125 inches, so a 1-1/8 inch socket or wrench fits. Head height is 15/32 inch, with a wrenching height of 0.324 inch, which matters if you're driving it in a counterbored or recessed pocket.
5) Can a zinc plated steel bolt like this be used outdoors or in a wet location?
Zinc plating over steel gives light corrosion resistance, fine for indoor mechanical rooms, equipment skids and general electrical, plumbing, heating and air conditioning work. For continuous outdoor exposure, washdown, or coastal service, specify hot dip galvanized or stainless instead; zinc plate will eventually rust in those conditions.
6) How many bolts come in a box of Metallics G5HC80, and can I buy fewer?
They ship as a box of 50 pieces, and 50 each is the order minimum, so it's a full-box item rather than a loose count. A box weighs 10.41 lbs. Metallics lists other sizes and quantities in the G5HC and JG5HC series by request.
7) Are nuts and washers included with Metallics G5HC80 bolts?
No. The box of 50 contains the hex cap screws only. Order 3/4-10 hex nuts and 3/4 inch flat or lock washers separately to complete the assembly.
8) What steel is this Grade 5 hex bolt made from?
Material is carbon steel to AISI 1008-1026, heat treated to Grade 5 properties, then zinc plated. That puts it in standard medium carbon cap screw territory, which is why it's rated 105,000 psi minimum tensile.
