Metallics BHC18 – Frequently Asked Questions
1) What thread does the Metallics BHC18 hex bolt take, and will it match a standard 5/16 nut?
The BHC18 is a 5/16-18 hex bolt, so 18 threads per inch, which is the standard coarse (UNC) pitch for 5/16 hardware. Any 5/16-18 nut, strut nut, or tapped channel will thread onto it. It is made to ASME B18.2.1-1996, so head and body dimensions follow the standard hex bolt spec.
2) Does this Metallics bolt qualify for a Buy American or ARRA funded job?
Metallics lists the BHC18 as both Buy American compliant and ARRA compliant, which is what a public agency or federally funded project submittal usually asks for. Country of origin is recorded as multiple.
3) What wrench or socket size fits the head on this Metallics hex bolt?
Head width across flats measures 0.484 to 0.500 inches, so a 1/2 inch wrench or socket is the correct size. That is the standard across-flats dimension for a 5/16 hex bolt.
4) Is a zinc plated steel bolt like this okay for outdoor or damp locations?
The BHC18 is steel with a zinc finish. Zinc plating handles indoor mechanical rooms, ceiling spaces, and covered exterior work. For continuously wet, coastal, or chemically aggressive locations, step up to stainless or hot dip galvanized instead, since plated zinc will eventually surface rust there.
5) How many bolts come in a box, and can I buy fewer than 100?
Sold as a box of 100, and 100 count is the order minimum, so it is a full-box item rather than a loose-piece buy. Other sizes and quantities are available by request.
6) How much does a box of 100 Metallics BHC18 bolts weigh?
A box runs 10.72 lbs, useful if you are totaling pallet or van weight across a bulk fastener order.
