Metallics JG5HSF38212 – Frequently Asked Questions
1) What size is the Metallics JG5HSF38212 hex head bolt?
It's a 3/8-16 x 2-1/2 inch bolt. The 3/8 is the nominal diameter, 16 is the threads per inch (standard UNC coarse thread for 3/8), and 2-1/2 inches is the length. It takes a 3/8-16 nut or a tapped 3/8-16 hole.
2) What does the serrated flange on this 3/8-16 bolt do, and do I still need a lock washer?
The JG5HSF38212 is an indented hex head serrated bolt. The serrations under the head bite into the mating surface as you torque it down, which resists loosening from vibration, so a separate lock washer generally isn't needed. The flip side: the serrations mar the surface, so it isn't for finished or soft material you care about.
3) How many bolts come in a jar of Metallics JG5HSF38212?
Fifty bolts per jar. Metallics packs this one as a jar rather than a bulk box, which is the format shops use for bench or truck stock on strut and channel work.
4) What is the Metallics part number I should order for the 3/8-16 x 2-1/2 serrated hex bolt?
Order Metallics JG5HSF38212. That single part number covers the 3/8-16 x 2-1/2 indented hex head serrated bolt in the 50-count jar, so there's no separate size or finish code to add.
5) Is this bolt the same thing as a hex flange bolt with a washer face?
Close but not identical. An indented hex head serrated bolt has a bearing surface with serrations machined into it, not the wide flared flange of a hex flange bolt. The serrated head locks against the material; a plain flange bolt spreads load over a larger area without the anti-rotation bite. If your spec calls for a flange to distribute clamp load on sheet metal, use a flange bolt or add a flat washer instead.
