Metallics G5HC74 – Frequently Asked Questions
1) What thread does the Metallics G5HC74 hex bolt take, and will a standard 3/4-10 nut thread onto it?
It's a 3/4-10 UNC bolt, 10 threads per inch, made to ASME B18.2.1-2012 dimensions. Any standard coarse-thread 3/4-10 nut or tapped hole will take it. The measured shank outside diameter runs 0.7410 to 0.7500 inch, which is the normal under-nominal range for a 3/4 inch bolt.
2) Is a Grade 5 zinc plated hex bolt strong enough for mounting a motor to a base?
Yes, and that's the intended use for the Metallics G5HC series. Grade 5 means medium carbon steel, quenched and tempered, with 105,000 psi minimum tensile and yield strength and a hardness of Rockwell C19-30. Metallics calls out motor mounting to machinery as a primary application, along with automotive and truck repair.
3) Will the Metallics G5HC74 meet a Buy American or ARRA requirement on a federal job?
No. The G5HC74 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your contract carries a domestic-content clause, this bolt will not satisfy it and you'll need a documented domestic Grade 5 bolt instead.
4) What size wrench or socket fits a Grade 5 3/4-10 hex bolt?
Across the flats the hex head measures 1.100 to 1.125 inch, so a 1-1/8 inch wrench or socket is the right fit. Head height is 15/32 inch, and wrenching height is 0.324 inch, so you need about a third of an inch of clear flat engagement, which matters if you are driving it in a recessed pocket or against a raised boss.
5) Is zinc plated steel OK for outdoor or damp mechanical room use?
Zinc plating on carbon steel is a mild corrosion barrier, fine for indoor mechanical rooms, equipment skids, and sheltered locations. It is not a marine or sustained wet-exposure finish. For direct weather, roof curbs, or wash-down areas, step up to hot dip galvanized or stainless. The G5HC74 is steel with a zinc finish.
6) Can I buy the Metallics G5HC74 bolt individually, or only by the box?
It ships as a box of 50 each, and 50 is the order minimum. If you need a different quantity or a different length or diameter in the same Grade 5 hex bolt line, Metallics offers other sizes and pack quantities on request.
7) What size hole should I drill or punch for this 3/4 inch hex bolt?
With a shank measured at 0.7410 to 0.7500 inch, a 13/16 inch hole gives standard clearance and 7/8 inch gives oversize clearance for field adjustment. Do not try to pass it through a 3/4 inch hole; there's no clearance. Threaded holes should be tapped 3/4-10.
8) Is this the right bolt for electrical and HVAC equipment anchoring work?
That's the market it's built for. Metallics lists the field application as the electrical, plumbing, heating, and air conditioning industries, which covers equipment bases, unit mounting, and strut and channel connections where a Grade 5 fastener is specified. The steel is in the AISI 1008 to 1026 range, heat treated to Grade 5 properties.
9) How much does a box of 50 of these 3/4-10 x 1-1/2 bolts weigh for freight planning?
The packed box weighs 5.3 lbs. That's useful if you are staging multiple boxes on a cart or figuring a parcel shipment for a service truck restock.
