Metallics G5HC2M – Frequently Asked Questions
1) What wrench or socket size fits the Metallics G5HC2M 1/4-20 hex bolt?
The hex head measures 0.428 to 0.438 inch across the flats, which is a 7/16 inch wrench or socket. Standard hex cap screw dimensions per ASME B18.2.1-2012.
2) Is the G5HC2M bolt coarse thread, and what nut do I pair it with?
It is 1/4-20, 20 threads per inch, which is the UNC coarse pitch for 1/4 inch diameter. Pair it with a 1/4-20 coarse nut; a 1/4-28 fine nut will not thread on. Shank diameter runs 0.2450 to 0.2500 inch.
3) Is a Grade 5 bolt strong enough for mounting a motor to machinery?
Yes, that is the intended use. Grade 5 means medium carbon steel, heat treated, with 120,000 psi minimum tensile and 92,000 psi minimum yield, hardness Rockwell C25-34. That is the normal spec for motor mounting, equipment anchoring, and automotive or truck repair work. If your drawing calls out Grade 8, this is not a substitute.
4) How many bolts come in a box of Metallics G5HC2M, and can I buy fewer?
These ship as a box of 1,000 pieces, and 1,000 is the order minimum. Smaller counts are not broken out of the box. Other sizes and quantities in the G5HC series are available by request.
5) Will a zinc plated steel bolt hold up outdoors or on a rooftop unit?
Zinc plating on steel is a mild corrosion coating meant for dry or sheltered service, which covers most electrical, plumbing, heating and air conditioning work. For sustained weather exposure, coastal air, or wet rooftop duty, specify hot dip galvanized or stainless instead of zinc plated.
6) Does the Metallics G5HC2M hex bolt meet Buy American or ARRA requirements on a public job?
The record flags it as compliant for both ARRA and Buy American, and the country of origin is China. On a federally funded project where the specification requires domestic melt and manufacture, confirm which standard your contract is written to before you submit these.
7) What does a full box of 1/4-20 x 1 Grade 5 hex bolts weigh and how big is the carton?
The box of 1,000 runs 17.5 lbs, with carton dimensions given as 7.25 x 6.25 x 6 inches. Easy for one person to carry to a mechanical room or up a ladder platform.
8) What steel is used in these Metallics Grade 5 hex cap screws?
Carbon steel in the AISI 1008 to 1026 range, heat treated to Grade 5 properties, then zinc plated. The hardness lands at Rockwell C25-34, so the heads take a 7/16 socket at full torque without rounding the way an unhardened Grade 2 bolt can.
