Metallics JG9HC12 – Frequently Asked Questions
1) Is a Grade 9 hex cap screw stronger than the Grade 5 or Grade 8 bolts I normally use?
Yes. The JG9HC12 is a Grade 9 hex cap screw, which sits above both Grade 5 and Grade 8 in tensile strength in the standard SAE bolt grading system. It is the one to reach for where a Grade 8 is marginal on a high-load or high-vibration connection. If your drawing calls out Grade 5 or Grade 8 specifically, note that substituting a higher grade changes the joint's behavior, so confirm the spec allows it.
2) How many bolts come in a pack of Metallics JG9HC12?
They ship 25 to a jar. The jar pack is the handy size for a service van or a parts bin rather than a bulk box, so figure one jar per 25 fasteners you need.
3) What is the difference between a hex cap screw and a hex bolt for a 3/8-16 connection?
A hex cap screw like the JG9HC12 is made to tighter tolerances than a common hex bolt, with a smaller, more consistent head and a chamfered thread end, so it threads into a tapped hole cleanly and seats square under the head. A hex bolt is the looser-tolerance version intended mainly for through-bolting with a nut. For tapped holes in strut, enclosures, and machine frames, the cap screw is the right pick.
4) Are nuts and washers included with the Metallics JG9HC12?
No. The jar of 25 contains the 3/8-16 x 1 Grade 9 hex cap screws only. Order 3/8-16 nuts and 3/8 flat or lock washers separately, and match the washer hardness to the bolt grade so the washer does not deform under a Grade 9 clamp load.
5) Can I use these Grade 9 cap screws for mounting electrical enclosures and strut hardware?
That is the intended use. Metallics catalogs the JG9HC12 as an electrical fastener, and 3/8-16 is the common thread for strut channel nuts, beam clamps, trapeze hangers, and enclosure mounting brackets. The 1 inch length works where the bracket and channel stack stays thin.
