Metallics JG5HSF121 – Frequently Asked Questions
1) What thread size and length is the Metallics JG5HSF121 hex flange bolt?
The Metallics JG5HSF121 is a 1/2-13 x 1 inch indented hex head bolt with a serrated flange. The 1/2-13 designation means a 1/2 inch diameter with 13 threads per inch, which is the standard UNC coarse thread for that diameter, so it mates with any standard 1/2-13 nut or tapped hole. Shank length is 1 inch under the head.
2) Do I need a separate washer with a serrated flange bolt like the JG5HSF121?
No. The flange under the head of the JG5HSF121 spreads the clamp load the way a washer would, and the serrations on the underside of that flange bite into the mating surface to resist loosening under vibration. That is the point of the design, so no washer or lock washer is ordered alongside it. On soft or finished surfaces the serrations will mar the material, so use a plain hex bolt and washer there instead.
3) Is the JG5HSF121 bolt meant for electrical work or general construction?
It is catalogued by Metallics as an electrical fastener, which is how electrical contractors buy it for grounding lugs, enclosure and panel mounting, strut and channel assembly, and busway or tray hardware. Nothing about a 1/2-13 x 1 inch serrated flange hex bolt limits it to electrical use, though; it is a standard coarse thread fastener and mechanical trades use the same part.
4) What size wrench or socket drives a 1/2-13 hex flange bolt?
A 1/2-13 hex head bolt takes a 3/4 inch wrench or socket in standard US sizing. Note that the JG5HSF121 has a flange under the head, so a deep socket or a thin wall socket clears better than an open end wrench when the bolt sits close to a rib or a channel wall.
