Metallics JG9HC7 – Frequently Asked Questions
1) What thread size and length is the Metallics JG9HC7 hex cap screw?
It's a 1/4-20 x 2 inch hex cap screw. The 1/4-20 callout is a 1/4 inch nominal diameter with 20 threads per inch, which is the standard UNC coarse thread for that diameter, so it mates with any standard 1/4-20 nut or tapped hole. The 2 inch figure is the shank length under the head, not the overall length, so figure your grip plus enough thread for the nut.
2) What does Grade 9 mean on a hex cap screw, and when would I use one instead of Grade 5 or Grade 8?
Grade is the strength class of the fastener. Grade 9 sits above Grade 8, which sits above Grade 5, so the JG9HC7 is for connections where a lower grade is being stretched or sheared, structural brackets, equipment mounts, and high-vibration anchorage. If you are bolting light sheet metal or a non-structural strap, a Grade 5 is normally all the spec calls for and the extra strength buys you nothing. Never substitute a lower grade into a joint an engineer specified as Grade 8 or 9.
3) How many bolts come in the Metallics JG9HC7 package?
25 pieces, supplied in a jar rather than a loose box. That pack size suits a service truck or a shop drawer where you want the count intact and the bolts kept together; if you are bolting out a large run you'll need multiple jars to cover the piece count.
4) What nut do I need with a 1/4-20 x 2 Grade 9 hex cap screw?
Any standard 1/4-20 nut threads onto it, but match the nut's strength to the bolt. Pairing a Grade 9 screw with a low-grade nut means the nut strips before the bolt ever reaches its working load, so order a hardened hex nut rated to Grade 8 or higher for the joint to perform. Flat washers under the head and nut are worth adding on anything structural to spread the bearing load. Nuts and washers are not included with the 25 piece jar.
5) What part number do I order for the Metallics 1/4-20 x 2 Grade 9 hex cap screw?
Order Metallics JG9HC7. That number covers the 1/4-20 x 2 inch Grade 9 hex cap screw in the 25 piece jar, so if you are matching a reorder off a packing slip or standardizing a fastener bin, JG9HC7 is the single designation to quote.
6) Is this bolt used for electrical work or general mechanical fastening?
Metallics catalogs the JG9HC7 as an electrical supply fastener, the kind used for mounting enclosures, strut, equipment frames, and gear to steel. Nothing about a 1/4-20 x 2 Grade 9 hex cap screw limits it to electrical work though, it is a standard inch-series machine bolt and the same piece serves general mechanical assembly.
