Metallics JG9HC23 – Frequently Asked Questions
1) What thread size and length is the Metallics JG9HC23 hex cap bolt?
The JG9HC23 is a 1/2-13 x 2-1/4 inch hex cap bolt. The 1/2-13 callout is 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 1/2-13 nut or tapped hole. Grip length runs 2-1/4 inches overall under the hex head.
2) What nuts and washers do I need for a 1/2-13 Grade 9 hex cap bolt?
Anything cut to 1/2-13 UNC will thread on, so a standard 1/2-13 hex nut and a 1/2 inch washer or lock washer. Nuts and washers are not part of the JG9HC23 jar, which is bolts only, so order them separately. On a high strength Grade 9 bolt it is normal practice to pair it with a hardened nut and hardened washer so the fastener, not the nut, is the strength limit.
3) How many bolts come in a jar of Metallics JG9HC23?
Twenty-five bolts per jar. The jar pack is the sales unit for the JG9HC23, so ordering one gets you 25 pieces of the 1/2-13 x 2-1/4 Grade 9 hex cap bolt rather than a single fastener. Useful for a service van or a shop bin where you are pulling the same size repeatedly.
4) Is a Grade 9 bolt the same as a Grade 5 or Grade 8?
No. Grade markings step up in strength, and Grade 9 sits above the common Grade 5 and Grade 8 hex cap screws used in general assembly work. The JG9HC23 is specified as Grade 9, so it is not interchangeable in the other direction either: if a drawing calls for Grade 9, substituting a Grade 5 or Grade 8 of the same 1/2-13 x 2-1/4 size gives you the right thread and length but not the specified strength.
5) What is the exact part number to order for the Metallics 1/2-13 x 2-1/4 Grade 9 hex cap bolt?
Order Metallics JG9HC23. That number covers the 1/2-13 x 2-1/4 Grade 9 hex cap bolt supplied as a 25 piece jar. The JG prefix is the jar pack designation, so if you need a different count or a bulk box the part number changes even though the bolt itself is the same size and grade.
