Metallics JG9HC20 – Frequently Asked Questions
1) What size and thread is the Metallics JG9HC20 hex cap bolt?
It's a 1/2-13 x 1-1/4 inch hex cap screw. The 1/2-13 means a 1/2 inch diameter with 13 threads per inch, which is the standard UNC coarse pitch for that diameter, so it mates with any standard 1/2-13 nut or tapped hole. Shank length is 1-1/4 inches under the head.
2) What does Grade 9 mean on a hex cap screw, and when do I need it?
Grade 9 is a higher-strength fastener class than the common Grade 5 or Grade 8 hex cap screws, so it's what gets specified where the connection sees heavy structural or vibration loading and a lower-grade bolt would be the weak link. The JG9HC20 is a Grade 9 bolt in 1/2-13 x 1-1/4. If your drawing calls out Grade 5, you can't substitute down, but a Grade 9 meets or exceeds a Grade 5 or 8 strength callout for the same size.
3) Do nuts or washers come with the Metallics JG9HC20 bolts?
No. The jar holds 25 bolts only. Order 1/2-13 hex nuts and any flat or lock washers separately, and match the nut grade to the bolt so the Grade 9 strength isn't lost at the nut.
4) Is a 1-1/4 inch long bolt long enough for my connection?
The 1-1/4 inch length is measured under the head, so it covers your combined material thickness plus the nut and any washers. On a short 1/2 inch bolt like this, much of that length is threaded, so it works well for thinner stacked steel, strut connections, and tapped holes. If your grip is much over about an inch once washers are added, step up to a longer 1/2-13 bolt rather than running the nut off the end.
5) Is the Metallics JG9HC20 a hex head bolt or a socket cap screw?
Hex head. It's a hex cap screw, driven with a wrench or socket, not an Allen key. For a 1/2-13 hex cap screw the head takes a 3/4 inch wrench.
6) What part number do I order for the 1/2-13 x 1-1/4 Grade 9 hex cap bolt from Metallics?
Metallics part number JG9HC20. That single MPN covers the 1/2-13 x 1-1/4 Grade 9 hex cap screw in the 25-piece jar, so there are no further options to specify when ordering.
