Metallics JG5HC68 – Frequently Asked Questions
1) What thread and size is the Metallics JG5HC68 hex bolt, and will it take a standard 5/8-11 nut?
It's a 5/8-11 coarse thread hex bolt, 3 inches long, with 11 threads per inch, so it mates with any standard 5/8-11 UNC nut or tapped hole. Shank outside diameter runs 0.6170 to 0.6250 inch. Threads are made to ASME B18.2.1-2012.
2) Is a Grade 5 bolt strong enough for bolting a motor to a base, or do I need Grade 8?
Grade 5 medium carbon steel, heat treated, with 105,000 psi minimum tensile and yield and a hardness of Rockwell C19-30. That is the normal choice for mounting motors to machinery and for automotive and truck repair work, which is exactly what this bolt is made for. Step up to Grade 8 only where the engineer calls out the higher strength class for a high-preload or shock-loaded joint.
3) Can I use these zinc plated bolts outdoors or in a damp mechanical room?
The finish is zinc plating over steel, which handles indoor and sheltered damp conditions like mechanical rooms, equipment pads and truck chassis work. It is not a marine or constant wet-exposure coating, so for direct weather over the long haul or corrosive environments, specify hot dip galvanized or stainless instead.
4) How many bolts come in a jar of Metallics JG5HC68, and is there a minimum order?
These ship 25 bolts to a jar. The order minimum is 50 count, so you are buying two jars at a time. Other sizes and quantities are available by request.
5) What steel are these Metallics Grade 5 hex bolts made from?
Medium carbon steel in the AISI 1008 to 1026 range, heat treated to reach Grade 5 properties: 105,000 psi minimum yield and Rockwell C19-30 hardness. Plain steel, not stainless, so the zinc plating is what provides the corrosion protection.
6) Are these bolts suitable for electrical and HVAC equipment mounting, or are they just general hardware?
Metallics builds the G5HC and JG5HC Grade 5 hex bolts for the electrical, plumbing, heating and air conditioning trades, so they are the standard choice for hanging and anchoring equipment on those jobs: strut assemblies, condenser and air handler mounts, pump and motor bases. Same bolt works as general structural hardware at Grade 5 strength.
7) Is the Metallics JG5HC68 bolt domestic, and can I use it on a Buy American job?
Country of origin is listed as multiple, meaning the jar can come from more than one source country. For a job with a hard Buy American or ARRA requirement, treat this as a non-domestic item and source a certified domestic Grade 5 hex bolt instead.
