Metallics JG5HC45 – Frequently Asked Questions
1) What thread and size is the Metallics JG5HC45 hex bolt, and what nut do I need with it?
It's a 3/8-16 bolt, 1 inch long, so it takes any 3/8-16 UNC nut or a tapped 3/8-16 hole. Measured shank diameter runs 0.3690 to 0.3750 inch and the thread is cut to ASME B18.2.1-2012, so it mates with standard off-the-shelf 3/8 coarse hardware.
2) Is a Grade 5 bolt strong enough to mount a motor to a machine base?
Yes, that's the intended use for the JG5HC45. Grade 5 medium carbon steel, heat treated to Rockwell C25-34, with 120,000 psi minimum tensile and 92,000 psi minimum yield. That's the standard structural-duty cap screw for motor mounts, equipment bases, and automotive or truck repair work.
3) Do these Metallics Grade 5 bolts qualify for a Buy American or ARRA funded job?
No. The JG5HC45 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project has domestic sourcing requirements, these will not satisfy them.
4) What wrench or socket size fits these 3/8-16 Grade 5 hex bolts?
Head width across flats is 0.551 to 0.562 inch, which is a 9/16 inch wrench or socket. Head height is 15/64 inch, so clearance under a socket is tight but normal for a 3/8 hex cap screw.
5) Will zinc plated steel bolts hold up in an outdoor or damp mechanical room?
The finish is zinc on steel, which handles indoor and sheltered mechanical rooms, panel work, and strut or equipment mounting. For sustained outdoor exposure, washdown, or coastal air, zinc plating will eventually corrode and a stainless or hot dip galvanized fastener is the better call.
6) How many bolts come in a jar of Metallics JG5HC45, and can I buy fewer?
The JG5HC45 ships as a jar of 100 pieces, and 100 is the order minimum, sold by the jar. Other sizes and quantities in the G5HC and JG5HC line are available by request.
7) What steel are Metallics G5HC hex bolts made from?
They're made from medium carbon steel in the AISI 1008-1026 range and then heat treated, which is what brings them up to Grade 5 hardness of Rockwell C25-34.
8) Are these bolts suited to electrical and HVAC trade work or just machinery?
Both. Metallics lists the field application as electrical, plumbing, heating and air conditioning, and the description calls out motor mounting plus automotive and truck repair. It's a general-purpose 3/8-16 Grade 5 cap screw for equipment and support anchoring across those trades.
