Metallics G5HC144 – Frequently Asked Questions
1) What thread and diameter is the Metallics G5HC144 hex bolt, and what nut does it take?
It's a 3/4-10 bolt: 3/4 inch nominal diameter with 10 threads per inch, which is standard UNC coarse thread for that size. Measured shank outside diameter runs 0.7410 to 0.7500 inches. Any 3/4-10 UNC nut or tapped 3/4-10 hole will take it. Dimensions follow ASME B18.2.1-2012.
2) Is a Grade 5 bolt strong enough for mounting a motor to a machine base?
Yes. The G5HC144 is Grade 5 medium carbon steel, heat treated, with 105,000 psi minimum tensile and yield strength and a hardness of Rockwell C19-30. Motor mounting to machinery is exactly what this cap screw is used for, along with automotive and truck repair work. If your drawing calls for Grade 8, this isn't the substitute.
3) Does this Metallics hex bolt qualify for a Buy American or ARRA funded project?
Metallics lists the G5HC144 as both Buy American compliant and ARRA compliant. Country of origin is recorded as multiple, so if your contract requires a single named origin on the certification, confirm the origin on the lot you receive.
4) What size wrench or socket fits the head on this 3/4-10 Grade 5 hex bolt?
Head width across flats measures 1.100 to 1.125 inches, so a 1-1/8 inch wrench or socket is the fit. Head height is 15/32 inch, with a wrenching height of 0.324 inch, so a thin-wall socket still gets enough purchase in a tight pocket.
5) Will a zinc plated steel bolt hold up outdoors or in a damp mechanical room?
The bolt is steel with a zinc plated finish, which handles indoor and sheltered mechanical spaces fine and gives moderate protection in damp conditions. For direct weather exposure, continuous wetting, or coastal air, zinc plating is not the right coating choice; go to hot dip galvanized or stainless in those spots.
6) How many bolts come in a box of Metallics G5HC144, and can I buy just a few?
They ship as a box of 50, and 50 each is the order minimum, so this is a full-box purchase rather than a loose-count item. Metallics makes other lengths and quantities in the G5HC and JG5HC series available by request.
7) How much does a box of 50 of these 3/4-10 bolts weigh for shipping or an overhead hanger load?
A full box of 50 weighs 29.12 lbs. Worth knowing if you're carrying several boxes up a ladder or figuring freight on a bulk fastener order.
