Metallics JG9HC36 – Frequently Asked Questions
1) What thread size and length is the Metallics JG9HC36 hex cap screw?
The JG9HC36 is a 3/4-10 x 4 inch hex cap screw. The 3/4-10 callout is the standard coarse (UNC) thread pitch for 3/4 inch diameter, so it mates with standard 3/4-10 nuts and tapped holes, and the 4 inches is the shank length under the head.
2) How many bolts come in a jar of Metallics JG9HC36?
25 bolts per jar. Pack type is a jar, not a loose box or bulk carton, so it stays sorted on a service truck or in a shop bin.
3) What does Grade 9 mean on a hex cap screw, and when would I use it over a Grade 8?
Grade 9 is a higher strength class than Grade 8, so it is what gets specified when a joint needs more clamp load than a Grade 8 fastener of the same 3/4 inch diameter can deliver, typically heavy structural, equipment mounting, and vibration-prone connections. For general bolting where the drawing calls out Grade 5 or Grade 8, a Grade 9 like the JG9HC36 is more fastener than the job needs. Always torque to the grade the engineer specified, not to the bolt's maximum.
4) Will a 4 inch long 3/4-10 bolt be long enough for my joint?
The JG9HC36 gives you 4 inches of shank under the head, so it covers a combined material stack plus washers and nut that comes in under that. Hex cap screws in this diameter are typically partially threaded, so if your grip length is close to 4 inches, check that enough thread engages the nut. For thicker stacks you need a longer 3/4-10 bolt instead.
5) Do nuts and washers come with the JG9HC36 bolts?
No. The jar contains 25 Grade 9 hex cap screws only, so order matching 3/4-10 nuts and 3/4 inch washers separately. For a Grade 9 bolt, pair it with a nut rated to the same strength class or you lose the benefit of the higher grade bolt.
6) Are these Metallics bolts suitable for electrical equipment and strut mounting work?
Yes. Metallics catalogs the JG9HC36 as an electrical-trade fastener, which is how it reaches electricians for equipment anchoring, switchgear and transformer mounting, and heavy support work. The 3/4-10 thread is the common size for large channel, beam clamps, and anchor rod connections at that scale.
