Metallics G5HC143 – Frequently Asked Questions
1) What thread and size is the Metallics G5HC143 hex bolt, and what nut do I need with it?
It's a 3/4-10 bolt: 3/4 inch nominal diameter with 10 threads per inch, which is the standard UNC coarse pitch at that diameter. Measured shank diameter runs 0.7410 to 0.7500 inches. Pair it with a 3/4-10 UNC nut; a fine-thread 3/4-16 nut will not thread on.
2) Does this Metallics hex bolt meet Buy American and ARRA requirements for a public project?
The G5HC143 is flagged compliant for both Buy American and ARRA. Country of origin is listed as multiple, so if your contract requires documented domestic melt and manufacture on each lot, request the cert with the order.
3) What wrench or socket size fits the head on this 3/4-10 Grade 5 hex bolt?
The hex head measures 1.100 to 1.125 inches across the flats, so a 1-1/8 inch socket or wrench is the fit. Across corners it runs 1.254 to 1.299 inches, and head height is 15/32 inch, which matters if you're torquing in a tight pocket or counterbore.
4) Is a zinc plated steel bolt like this suitable for outdoor or wet locations?
The finish is zinc plating over steel, which handles dry interior and sheltered service. For constant wetness, washdown, or coastal exposure, zinc plating will eventually corrode through; hot dip galvanized or stainless is the right call there.
5) How many bolts come in a box of Metallics G5HC143, and can I buy fewer?
It ships as a box of 25 each, and 25 is the order minimum, so a single bolt isn't an option. Other sizes and quantities are available by request.
6) What dimensional standard does this 3/4-10 hex bolt follow, so I know it matches what's already in the equipment?
Head and thread dimensions follow ASME B18.2.1-2012, the standard for inch hex bolts and screws, and the steel is AISI 1008-1026. So the head width and thread form interchange with any other B18.2.1 3/4-10 hex bolt of the same length.
7) What is this Grade 5 hex cap screw typically used for in the field?
It's a cap screw used for mounting motors to machinery, and it's common in automotive and truck repair. The field application list covers electrical, plumbing, heating, and air conditioning work, so think equipment mounting, pump and blower bases, and skid anchoring rather than wood framing.
8) What does a box of 25 of these 3/4 inch bolts weigh for shipping or a job box?
A full box of 25 comes in at 12.67 lbs, roughly half a pound per bolt. Worth knowing if you're staging several boxes on a cart or a lift.
