Metallics G5HC77D – Frequently Asked Questions
1) What thread and size is the Metallics G5HC77D 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 diameter. Measured shank diameter runs 0.7410 to 0.7500 inch. Any 3/4-10 UNC nut or tapped hole will mate with it. Threads are made to ASME B18.2.1-2012.
2) How thick a part can a 3/4-10 x 1 inch Grade 5 hex bolt actually clamp?
The bolt is only 1 inch long under the head, so total grip (material plus washers plus nut engagement) has to stay inside that. On a 3/4-10 bolt a short length like this is typically threaded full length, so it is best suited to tapped holes or thin flange-to-flange joints. If you are stacking a bracket plus washers plus a nut, step up to a longer length.
3) Is a Grade 5 bolt strong enough for mounting a motor to a machine base?
Grade 5 is the common medium-carbon, heat-treated structural fastener grade and it is what this bolt is made for, including motor-to-machinery mounting and automotive or truck repair work. It carries 120,000 psi minimum tensile and 92,000 psi minimum yield, with hardness at Rockwell C25-34. For higher-stress or fatigue-critical joints, specify Grade 8 instead.
4) Do these Metallics hex bolts qualify for a Buy American or ARRA funded project?
No. The G5HC77D is flagged not Buy American compliant and not ARRA compliant, even though country of origin is listed as the United States. If your contract carries a domestic-preference clause, get a fastener specifically certified to it rather than relying on this one.
5) What wrench or socket size fits the head on the Metallics G5HC hex bolt?
Across-flats head width measures 1.100 to 1.125 inch, so a 1-1/8 inch wrench or socket is the size to grab. Head height is 15/32 inch, with 0.324 inch of wrenching height, so a standard hex socket gets full purchase without bottoming on the flange.
6) Can these zinc plated steel bolts be used outdoors or in a wet area?
Finish is zinc plating over steel, which handles indoor industrial and sheltered conditions and gives moderate corrosion resistance. Zinc plating is sacrificial and will eventually rust in standing water, salt spray or washdown service, so for exterior or corrosive duty use hot dip galvanized or stainless fasteners instead.
7) How many bolts come in a box of Metallics G5HC77D, and is there an order minimum?
They ship as a box of 100, and 100 count is the order minimum, so the box is the smallest buying unit. Metallics notes other sizes and quantities are available by request if 3/4-10 x 1 is not the length you need.
8) What steel is used in the Metallics G5HC Grade 5 hex bolt?
Material is carbon steel to AISI 1008-1026, heat treated as a cap screw. That is what puts it in the Grade 5 strength class at Rockwell C25-34. It is not a stainless or alloy bolt, so do not substitute it where a corrosion-resistant or Grade 8 alloy fastener is specified.
