Metallics JG5HC25D – Frequently Asked Questions
1) Is a grade 5 bolt strong enough for mounting a motor to a machine base?
Yes, that's the intended use. The JG5HC25D is a medium carbon steel cap screw, heat treated to Grade 5 with a minimum 105,000 psi tensile and yield strength and a hardness of Rockwell C19-30. Metallics lists motor mounting as the primary application, along with automotive and truck repair. If your drawing calls out Grade 8 or a specific alloy, this is not a substitute.
2) Do these Metallics hex bolts qualify for a Buy American or ARRA funded project?
Yes. The JG5HC25D is listed as both Buy American compliant and ARRA compliant, with country of origin the United States. That covers the documentation most government, school, and federally funded jobs ask for on fasteners.
3) What size wrench or socket do I need for 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 15/64 inch, so clearance above the joint is minimal if you're working in a tight pocket.
4) Can these zinc plated bolts be used outdoors or in a damp location?
The finish is zinc plating over steel, which handles indoor and sheltered conditions and incidental moisture. It is not stainless. For continuous wet exposure, direct weather, or coastal and corrosive environments, step up to hot dip galvanized or stainless fasteners instead.
5) How many bolts come in the Metallics JG5HC25D jar, and is there a minimum order?
Each jar holds 50 bolts, and 50 count is the order minimum, so one jar is the smallest buy. Jar packaging keeps loose hardware contained on a service truck or a parts shelf. Metallics notes other sizes and quantities are available by request.
6) What material spec is behind the Metallics G5HC/JG5HC bolt series?
Stock for the G5HC and JG5HC series is AISI 1008 to 1026 steel, a medium carbon range, then heat treated to reach Grade 5 properties. That's the detail a submittal reviewer or spec writer usually wants alongside the grade marking.
