Metallics JG5HC26 – Frequently Asked Questions
1) Is 3/8-16 coarse or fine thread, and will it take a standard 3/8 nut?
It is 16 threads per inch, which is the coarse (UNC) pitch for 3/8 in. diameter, so it mates with any standard 3/8-16 nut or tapped coarse hole. Threads are made to ASME B18.2.1-2012. If your tapped hole or nut is 3/8-24 fine, this bolt will not thread in.
2) Will a 3/8-16 Grade 5 hex bolt pass through a 3/8 in. drilled hole?
Shank outside diameter is 0.3690 to 0.3750 in., so it is a slip fit in a 7/16 in. hole and will bind in a nominal 3/8 in. (0.375) drilled hole. Drill 7/16 for clearance, or tap 5/16 for a 3/8-16 thread.
3) What wrench size do I need for a 3/8-16 Grade 5 hex bolt like the Metallics JG5HC26?
Head width across the flats runs 0.551 to 0.562 in., which is a 9/16 in. wrench or socket. Head height is 15/64 in., with a wrenching height of 0.16 in., so a standard six-point socket gets full purchase on the head without camming off.
4) Is a zinc plated steel bolt OK outdoors or in a damp mechanical room?
The JG5HC26 is steel with a zinc finish, which handles indoor mechanical rooms, equipment mounting and general MRO work well. Zinc plating gives limited protection in constant wet, coastal or chemical exposure; for those openings use a hot dip galvanized or stainless fastener.
5) Do these Metallics bolts meet Buy American or ARRA requirements on a federal job?
No. The JG5HC26 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project has domestic sourcing requirements written into the spec, this is not the fastener to submit.
6) How many bolts come in the Metallics JG5HC26 jar?
Fifty bolts per jar, sold as a jar pack with a 50 each minimum. That is the quantity format electrical, plumbing and HVAC crews buy for truck stock, since the jar keeps one size separated rather than loose in a bin.
7) What steel is used in Metallics G5HC Grade 5 hex bolts?
Material conforms to AISI 1008 through 1026, a medium carbon steel range, then heat treated to reach Grade 5 properties. That is what gets it to Rockwell C19-30 hardness, which is why it holds torque on equipment mounts better than an unhardened Grade 2 bolt of the same size.
