Metallics JG5HC45D – Frequently Asked Questions
1) What thread and size is the Metallics JG5HC45D hex bolt, and will it thread into a 3/8-16 tapped hole?
It's a 3/8-16 UNC hex cap screw, 1 inch long under the head. Thread pitch is 16 threads per inch and the thread conforms to ASME B18.2.1-2012, so it threads into any standard 3/8-16 coarse tapped hole or nut. Shank outside diameter runs 0.3690 to 0.3750 inch.
2) Is a Grade 5 bolt strong enough for mounting a motor to a machine base?
Yes, that's the intended use. Grade 5 means medium carbon steel, heat treated, rated at 120,000 psi minimum tensile and 92,000 psi minimum yield, with a hardness of Rockwell C25-34. That covers motor mounting, equipment bases, and automotive or truck repair work. If your drawing calls out Grade 8 or a specific proof load above these numbers, step up instead.
3) Do these Metallics hex bolts meet Buy American requirements on a federally funded job?
They're marked Buy American compliant with country of origin United States, which is what a government or institutional procurement officer needs on the submittal for a domestic-content job.
4) What size wrench or socket fits these 3/8-16 Grade 5 hex bolts?
The hex head measures 0.551 to 0.562 inch across the flats, which is a 9/16 inch wrench or socket. Head height is 0.226 to 0.243 inch, with 0.16 inch of wrenching height, so you need reasonably full socket engagement in tight recesses.
5) Will zinc plated Grade 5 bolts hold up outdoors or in a damp mechanical room?
The finish is zinc plating over steel, silver in appearance. That handles indoor mechanical rooms, equipment rooms, and general shop use well. For sustained outdoor exposure, washdown areas, or coastal salt air, zinc plating will eventually corrode, so hot dip galvanized or stainless is the better call there.
6) Do nuts and washers come with these bolts?
No. The JG5HC45D jar is bolts only, 100 hex cap screws. You'll need to order 3/8-16 nuts and 3/8 flat or lock washers separately to complete a through-bolted connection.
7) What steel are these Metallics G5HC bolts made from?
Material is steel to AISI 1008 through 1026, heat treated to Grade 5 properties. That's the medium carbon range that gets you the Rockwell C25-34 hardness and 120,000 psi tensile minimum.
