Metallics JG5HSF516112 – Frequently Asked Questions
1) What thread size and length is the Metallics JG5HSF516112 hex head bolt?
It's a 5/16-18 x 1-1/2 inch bolt, so 5/16 inch diameter with 18 threads per inch and a 1-1/2 inch shank length under the head. 5/16-18 is the UNC coarse series, which is what matches standard 5/16 coarse nuts, strut channel nuts, and tapped coarse holes.
2) Does the serrated hex head bolt need a separate lock washer?
No. The JG5HSF516112 has a serrated flanged hex head, and those serrations bite into the mating surface to resist loosening from vibration, which is the job a split lock washer would otherwise do. The flange also spreads load like an integral washer, so you can run it straight against a channel, bracket, or enclosure flange.
3) How many bolts come in a jar of Metallics JG5HSF516112?
100 pieces per jar. It ships as a jar pack, which is the usual way an electrician keeps a single size on the truck or at a bench without loose hardware spilling through a bag.
4) What is the exact part number to order this Metallics 5/16 hex bolt?
Order Metallics part number JG5HSF516112. That number covers the 5/16-18 x 1-1/2 indented hex head serrated bolt in the 100-count jar, so one number gets you the complete pack rather than loose pieces.
5) Is this an electrical fastener or a general construction bolt?
Metallics catalogs the JG5HSF516112 as an electrical supply fastener, and the serrated flanged hex head is the style typically used for grounding and bonding connections, panel and enclosure mounting, and strut work, where you want the fastener to stay tight without an added washer. It works anywhere a 5/16-18 x 1-1/2 bolt is called for, but the serrated head is what makes it a go-to for electrical rough-in.
