Metallics JBHC7 – Frequently Asked Questions
1) What size bolt is the Metallics JBHC7, and what nuts will it take?
The JBHC7 is a 1/4-20 x 3-1/2 inch hex bolt, so it takes any standard 1/4-20 nut or tapped 1/4-20 hole. Thread count is 20 threads per inch (UNC coarse), and the thread conforms to ASME B18.2.1-1996. Measured body diameter runs 0.237 to 0.260 in.
2) Is a Grade 2 zinc-plated bolt strong enough for strut, hangers and equipment mounting?
Grade 2 is the standard low-carbon steel strength class and is what gets used for general electrical, plumbing, and HVAC work: strut clamps, pipe hangers, box and enclosure mounting, equipment feet. The JBHC7 is Grade 2 steel with a zinc plating. For structural connections or anything carrying calculated load, step up to Grade 5 or Grade 8 instead.
3) Does the Metallics JBHC7 meet Buy American or ARRA requirements on a public project?
No. The JBHC7 hex bolt is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your contract carries a domestic-sourcing clause, this is not the fastener to put on the submittal.
4) What wrench or socket size fits these 1/4-20 hex bolts?
Across the flats the hex head measures 0.425 to 0.438 in., which is a 7/16 inch wrench or socket. That is the standard head size for a 1/4-20 hex bolt, so a 7/16 socket covers the whole jar.
5) Can I use these zinc-plated bolts outdoors or in a wet location?
Zinc plating is a light-duty corrosion coating. It holds up fine indoors, in mechanical rooms, and in dry or damp protected locations. For sustained exposure to weather, roof work, coastal air, or chemical washdown, specify hot-dip galvanized or stainless instead, because plated zinc will eventually rust through in those conditions.
6) How many bolts come in a jar, and can I order a smaller quantity?
The JBHC7 ships as a jar of 100 bolts, and that jar is the minimum order unit. Metallics does make other lengths and pack quantities in the BHC and JBHC series available by request if 100 pieces of 3-1/2 inch is not what the job needs.
7) Do nuts and washers come with the Metallics JBHC7 jar?
The jar is bolts only, 100 hex bolts in 1/4-20 x 3-1/2. Order 1/4-20 hex nuts and 1/4 inch flat or lock washers separately if the connection needs them. Match the zinc finish on the nuts and washers so you don't set up dissimilar-metal corrosion at the joint.
8) How much does a jar of 100 Metallics hex bolts weigh for shipping?
A full jar comes in at 3.92 lbs for the 100 pieces. Useful if you are staging fastener stock on a cart or working to a weight allowance on a job box.
