Metallics JG5HSF38214 – Frequently Asked Questions
1) What thread size and length is the Metallics JG5HSF38214 bolt?
It's a 3/8-16 thread, 2-1/4 inches long, with an indented hex head and a serrated flange. The 2-1/4 inch length gives you enough grip for a thicker assembly plus the nut; for thinner stack-ups you'd want a shorter bolt in the same thread.
2) What does the serrated flange on this Metallics hex head bolt do?
The serrations under the flange head bite into the mating surface and resist loosening under vibration, so you don't need a separate lock washer. The flange also spreads the load over a wider area than a plain hex head, which helps on sheet metal, strut, and enclosure work.
3) How many bolts come in a jar of Metallics JG5HSF38214?
100 pieces, packed in a jar. That's a shop or van quantity for repetitive electrical mounting work rather than a single-job count.
4) What nut do I need with a 3/8-16 serrated flange bolt?
Any 3/8-16 nut will thread on, since 3/8-16 is the standard coarse thread for that diameter. Nuts are not included with the bolts, so order them separately. If you want the same vibration resistance on the nut side, pair it with a serrated flange nut in 3/8-16.
5) What size hole do I drill for a 3/8-16 bolt?
For a 3/8-16 bolt passing through a clearance hole, drill 7/16 inch. If you're tapping the material instead of using a nut, a 3/8-16 tap calls for a 5/16 inch pilot. Either way the bolt body is 3/8 inch nominal.
6) Is the Metallics JG5HSF38214 bolt meant for electrical installation work?
Yes. Metallics catalogues it as an electrical fastener, and it's the type of bolt used for mounting strut, hangers, panels, and enclosures on electrical jobs. It works as a general machine bolt anywhere a 3/8-16 x 2-1/4 flanged hex bolt is called for.
7) What is the Metallics part number for the 3/8-16 x 2-1/4 serrated hex bolt?
The manufacturer part number is JG5HSF38214. Order against that number to get the 3/8-16 x 2-1/4 indented hex head serrated flange bolt in the 100 piece jar rather than a plain hex bolt of the same size.
