Metallics JBHC16 – Frequently Asked Questions
1) What thread does the Metallics JBHC16 hex bolt use, and will it take a standard 5/16-18 nut?
The JBHC16 is a 5/16-18 hex bolt, meaning 18 threads per inch on a 5/16 inch diameter, cut to ASME B18.2.1-1996. That is the standard coarse (UNC) pitch for 5/16 inch, so any off-the-shelf 5/16-18 coarse nut or tapped 5/16-18 hole will thread onto it. Measured thread diameter runs 0.298 to 0.324 inch.
2) Can I use the Metallics JBHC16 on a federally funded Buy American job?
No. The JBHC16 is listed as not Buy American compliant and not ARRA compliant, with multiple countries of origin. For a project with domestic sourcing requirements you will need a fastener carrying a documented domestic origin.
3) What wrench or socket size fits the head on this Metallics 5/16 hex bolt?
Head width across flats is 0.484 to 0.500 inch, so a 1/2 inch wrench or socket is the size to carry. Head type is a standard hex.
4) Is a zinc plated steel bolt like the JBHC16 OK for outdoor or damp locations?
The JBHC16 is zinc plated carbon steel. Zinc plating handles indoor and protected-exterior service, mechanical rooms, and general dry conduit and equipment mounting. For sustained wet exposure, direct weather, coastal air, or anything buried or in contact with treated lumber, go to hot dip galvanized or stainless instead, since plated zinc is a thin sacrificial coating and will eventually bleed rust.
5) How does the JBHC16 ship and what is the minimum I can buy?
It ships as a jar of 100 bolts, and 100 (one jar) is the minimum order. The jar weighs 7.11 lbs. That packaging is aimed at a van or shop bin rather than a single repair, so plan on stocking the quantity.
6) Do these bolts come with nuts and washers?
No. The jar contains the 5/16-18 x 3 inch hex bolts only. You will need to order 5/16-18 hex nuts and 5/16 flat or lock washers separately to complete the assembly.
7) Is there a different size in the Metallics BHC hex bolt line if 5/16-18 x 3 is not what I need?
The BHC and JBHC series runs other diameters, lengths, and pack quantities beyond the 5/16-18 x 3 inch JBHC16, available by request. Specify the diameter and thread pitch, the length under the head, and whether you want the jar pack or bulk when you ask.
