Metallics JBHC20 – Frequently Asked Questions
1) What thread does the Metallics JBHC20 5/16 hex bolt take, and will a standard 5/16-18 nut fit it?
It is a 5/16-18 thread, 18 threads per inch, which is the standard UNC coarse pitch for 5/16 inch diameter. Any 5/16-18 coarse nut or coarse-tapped channel will thread onto it. The bolt is made to ASME B18.2.1-1996 for hex bolt dimensions, so head and body sizing follow the standard rather than a proprietary pattern.
2) What grade is the Metallics 5/16-18 x 5 hex bolt, and is it strong enough for pipe and strut hanging?
Grade 2 steel. That is the common commercial grade used for electrical, plumbing and HVAC support work, which is exactly the field application Metallics lists for this bolt. It is fine for strut, trapeze, box and general equipment mounting. If the drawing calls for Grade 5 or Grade 8 on a structural or seismic connection, this is not the bolt for it.
3) What hole size do I drill for the Metallics 5/16-18 hex bolt?
Body outside diameter runs 0.298 to 0.324 inch, so a 5/16 inch (0.3125) hole is a tight fit and a 3/8 inch hole gives normal clearance for field work. Standard 5/16 strut holes and knockouts accept it without reaming.
4) Can I use the Metallics JBHC20 bolts on a Buy American or ARRA funded job?
No. Metallics lists the JBHC20 as neither Buy American compliant nor ARRA compliant, with country of origin recorded as multiple. On federal, state, or institutional work carrying domestic sourcing requirements you need a domestically produced bolt instead.
5) What size wrench or socket does a 5/16-18 Metallics hex bolt need?
Head width across flats measures 0.484 to 0.500 inch, so a 1/2 inch wrench or socket is the right tool. That is the standard hex size for a 5/16 inch bolt, so no odd metric socket is needed in the van.
6) Is a zinc plated steel hex bolt like the JBHC20 OK for outdoor or damp mechanical rooms?
The JBHC20 is steel with a zinc finish. Zinc plating handles indoor and sheltered damp locations, mechanical rooms and interior strut runs. For direct weather exposure, wash-down, or coastal work, step up to hot dip galvanized or stainless hardware instead, because plated zinc is a thin sacrificial coating and will eventually rust through in standing water.
7) How much material can a 5 inch long 5/16 bolt actually clamp through?
The bolt is 5 inches long under the head, so it will pass through thick build-ups, stacked strut, timber blocking, or doubled channel with room for a washer and nut. On thinner connections you will have excess thread standing proud, so order a shorter length from the BHC and JBHC series if a flush finish matters.
8) Do these bolts come with nuts and washers?
No. The JBHC20 jar contains hex bolts only. Add 5/16-18 hex nuts and 5/16 flat or lock washers separately to complete the assembly.
9) How are these Metallics 5/16 x 5 bolts packaged and what is the minimum order?
They ship in a jar of 100 pieces, and 100 (one jar) is the order minimum. Jar packaging keeps them sorted on a cart or shelf rather than loose in a bucket, which is why MRO stockrooms and service vans tend to buy them this way. Metallics notes other sizes and quantities are available by request.
10) How much does a jar of 100 Metallics 5/16-18 x 5 hex bolts weigh?
5.77 lbs for the full jar of 100. Worth knowing if you are loading several sizes onto a parts cart or spec'ing stockroom shelf capacity.
