Metallics JG5HCF43 – Frequently Asked Questions
1) Is the Metallics JG5HCF43 bolt a fine thread or coarse thread 5/16?
Fine thread. The JG5HCF43 is a 5/16-24 hex bolt, 24 threads per inch, which is UNF rather than the more common 5/16-18 UNC. It will not thread into an 18-pitch nut or tapped hole, so match the mating thread before you order. Shank diameter runs 0.3065 to 0.3125 in. and the thread conforms to ASME B18.2.1-2012.
2) What wrench or socket size fits this 5/16-24 Grade 5 hex bolt?
Head width across flats measures 0.489 to 0.500 in., so a 1/2 in. socket or wrench is the fit. Head height is 13/64 in. with a 0.14 in. wrenching height, which is worth checking if you are driving it in a recess or a counterbored pocket.
3) Can zinc plated Grade 5 bolts be used outdoors or in a wet location?
The finish is zinc, a zinc chromate plating over steel. That handles indoor industrial, machinery, and enclosed equipment work and gives light corrosion resistance. For sustained outdoor exposure, washdown, or coastal air, specify hot dip galvanized or stainless instead.
4) How many bolts come in a jar of Metallics JG5HCF43?
100 pieces per jar, and 100 count is the order minimum, so one jar is the smallest buy. The jar weighs 1320 g. The JG prefix on the part number is the jar pack; the same bolt in the G5HC series is the bulk equivalent. Other sizes and quantities can be requested.
5) Do these Metallics hex bolts qualify for a Buy American or ARRA funded job?
Metallics JG5HCF43 is flagged as both Buy American compliant and ARRA compliant. Country of origin is listed as multiple, so if your contract requires a single documented origin per lot, get that confirmed against the shipping lot.
6) What steel are these Grade 5 cap screws made from?
Medium carbon steel in the AISI 1008 to 1026 range, heat treated to reach Grade 5 properties. That is a weldable-with-caution carbon steel, not an alloy or stainless, and heat from welding will undo the heat treatment, so use it as a mechanical fastener only.
