Metallics JBHC15PL – Frequently Asked Questions
1) Will a 5/16-18 hex bolt thread into a standard 5/16 coupling nut or strut nut?
Yes. The Metallics JBHC15PL is a 5/16-18 hex bolt, meaning 18 threads per inch, which is the standard coarse (UNC) pitch for 5/16 inch fasteners. Any 5/16-18 nut, strut channel nut, or tapped insert takes it. Threads are made to ASME B18.2.1-1996, the dimensional standard for hex bolts, so head and thread geometry match other bolts built to that spec.
2) Is this a plated or plain finish bolt, and can I use it outdoors?
Plain finish steel, with no plating or coating. That makes it a dry-location fastener: indoor panel work, strut, enclosure and equipment mounting. Bare steel will surface rust in damp or exterior conditions, so for outdoor or washdown use pick a zinc-plated or stainless 5/16-18 hex bolt instead.
3) What wrench or socket size fits the head on the Metallics JBHC15PL hex bolt?
The hex head measures 0.484 to 0.500 inches across the flats, so a 1/2 inch wrench or socket is the one you want. Across corners it runs 0.552 to 0.577 inches, which matters if you are driving it in a tight channel or box where the corners have to clear.
4) How many bolts come in a jar, and is there an order minimum?
The JBHC15PL ships as a jar of 100 bolts, and 100 count is the order minimum, so one jar is the smallest buy. The jar pack is what makes this practical for a service van or a shop bin rather than loose bulk. Jar weight is 6.65 lbs.
5) Does this Metallics bolt meet Buy American requirements on a federal job?
Metallics lists the JBHC15PL as both ARRA compliant and Buy American compliant, which is the flag institutional and government procurement looks for. Note the country of origin on record is China, so if your specification demands domestic melt and manufacture rather than the compliance flag, verify against your contract language before you submit it.
6) Can I get this 5/16-18 hex bolt in a different length or a larger quantity?
The JBHC15PL is the 5/16-18 x 2-1/2 inch plain steel hex bolt in a 100 count jar. Metallics builds the BHC and JBHC series in other sizes and pack quantities, available by request, so if you need a shorter shank for thinner material or a bulk box instead of a jar, ask for the matching series number.
7) Is a plain steel hex bolt the right choice for mounting electrical equipment, or should I use a machine screw?
A 5/16-18 hex bolt suits heavier mounting work: transformer and enclosure anchoring, strut assemblies, equipment feet, anything you want to torque with a 1/2 inch socket rather than a driver. Machine screws in smaller diameters are the choice for device boxes, covers and light panel work. Go hex bolt when the load or the vibration justifies it and you have clearance for a wrench on both the head and the nut.
