Metallics JG5HC90 – Frequently Asked Questions
1) What thread and size is the Metallics JG5HC90 hex bolt, and will it take a standard 5/16-18 nut?
It's a 5/16-18 x 1-3/4 inch hex cap screw, so 18 threads per inch on a 5/16 diameter, which is the standard UNC coarse thread for that size. Shank outside diameter runs 0.3065 to 0.3125 inch. Any standard 5/16-18 coarse nut or tapped hole will take it.
2) What wrench or socket size fits the head on this Metallics Grade 5 hex bolt?
Head width across flats measures 0.489 to 0.500 inch, so a 1/2 inch wrench or socket is the fit. Head height is 13/64 inch.
3) Is the zinc plating on these bolts good enough for outdoor or damp locations?
The finish is zinc on steel, a zinc chromate type plating. That handles indoor and sheltered conditions and resists incidental moisture, but it is not stainless. For continuous outdoor exposure, salt, or wet process areas, step up to hot dip galvanized or stainless.
4) How many bolts come in a jar, and can I buy fewer than 100?
They ship in a jar of 100, and 100 count is the order minimum. Smaller counts aren't broken out. Other sizes and quantities can be arranged by request.
5) Do these Metallics hex bolts meet Buy American requirements for a government job?
The JG5HC90 is flagged compliant for both ARRA and Buy American. Country of origin is listed as multiple, so if your contract requires documented origin on each lot, ask for the cert with the shipment.
6) What dimensional standard do these Grade 5 hex bolts conform to?
Threads and head dimensions follow ASME B18.2.1-2012, and the steel is within the AISI 1008-1026 range. That means heads and threads interchange with any other B18.2.1 hex cap screw of the same size.
