Metallics JG5HC78 – Frequently Asked Questions
1) How many bolts come in a jar of the Metallics JG5HC78?
Twenty-five bolts per jar, and the jar is the minimum order quantity. Packed weight is 4,522 g. If you need a different count or a different length in the same Grade 5 hex bolt line, Metallics offers other sizes and quantities by request.
2) Will a zinc plated Grade 5 bolt hold up outdoors or in a damp mechanical room?
The finish is zinc, listed as zinc chromate on steel. That handles indoor mechanical rooms, equipment pads, and general shop work fine. It is a plated coating, not hot dip galvanized or stainless, so for direct weather exposure, marine air, or treated lumber contact you want a hot dip galvanized or stainless fastener instead.
3) Does the Metallics JG5HC78 meet a standard hex bolt dimensional spec?
Yes, it's made to ASME B18.2.1-2012, the dimensional standard for square and hex bolts and screws. That means head width across flats, head height, and thread form match any other B18.2.1 3/4-10 hex bolt, so it drops into the same clearance holes and takes the same standard 3/4-10 nuts and washers. Material is AISI 1008-1026 steel.
4) Is this bolt Buy American and ARRA compliant for a government or institutional job?
Metallics flags the JG5HC78 as both ARRA compliant and Buy American compliant. Country of origin on the record is China. If your contract language requires domestic melt and manufacture rather than the ARRA/Buy American designation, confirm which clause your spec is written to before you submit it.
5) How much grip length do I get out of a 2-1/2 inch Grade 5 hex bolt?
At 2-1/2 inches under the head, the JG5HC78 covers roughly a 2 inch stack of steel plus a nut and washers on a 3/4-10 thread. For thicker bases, motor feet on shims, or anywhere you need more than a couple of threads past the nut, step up in length rather than running the nut out to the end of the thread. Metallics carries the G5HC and JG5HC line in other lengths.
