Metallics JG9HC11 – Frequently Asked Questions
1) What thread size and length is the Metallics JG9HC11 hex cap screw?
The JG9HC11 is a 3/8-16 x 3/4 inch hex cap screw. That is a 3/8 inch diameter with 16 threads per inch (UNC coarse), and a 3/4 inch length under the head, so it suits thin stack-ups where a longer bolt would bottom out or protrude.
2) What does Grade 9 mean on this 3/8-16 hex cap screw, and is it stronger than Grade 8?
Grade 9 is the highest common strength class for inch-series structural fasteners, rated above Grade 8 and well above Grade 5. The JG9HC11 is a Grade 9 hex cap screw, so it is specified where joint clamp load or shear demand exceeds what a Grade 5 or Grade 8 bolt of the same 3/8 inch diameter will carry. Do not substitute a lower grade into an application that called out Grade 9.
3) How many bolts come in a Metallics JG9HC11 pack?
Twenty-five bolts, supplied in a jar rather than a loose bag or a bulk box. The jar pack is what keeps a single size separated on a service truck or in a shop bin, so you are buying a count of 25 of the 3/8-16 x 3/4 size, not a mixed assortment.
4) Will a 3/8-16 x 3/4 hex cap screw work with standard 3/8 inch nuts and washers?
Yes. The thread is 3/8-16 UNC, the standard coarse inch thread, so it mates with any 3/8-16 nut, and takes standard 3/8 inch flat and lock washers. For a Grade 9 bolt, match the nut strength to the bolt so the nut is not the weak point in the joint.
5) Is the JG9HC11 a bolt or a machine screw, and what tool drives it?
It is a hex cap screw, which means a hex head driven with a wrench or socket rather than a screwdriver or hex key. A 3/8 inch hex cap screw normally takes a 9/16 inch socket. Fully usable as a bolt through a clearance hole with a nut, or threaded into a tapped hole.
