Metallics JG9HC27 – Frequently Asked Questions
1) Will a 2 inch long 5/8 bolt be long enough for my connection?
At 2 inches of overall length under the head, the JG9HC27 covers a total grip (material thickness plus washers) of roughly an inch to an inch and a half once you leave thread for the nut to fully engage. For thicker stacked steel you need a longer 5/8-11 screw. Measure your grip first, then add about a diameter of thread for the nut.
2) Do nuts and washers come with the Metallics JG9HC27 bolts?
The jar contains the hex cap screws only. Nuts, flat washers, and lock washers in 5/8 inch are ordered separately, and for a Grade 9 screw you want hardened washers and a matching high-strength nut so the joint is not limited by the weakest part.
3) Is a Grade 9 hex cap screw stronger than Grade 8?
Grade 9 sits above Grade 8 in the SAE strength ladder, which is why it gets specified on high-vibration and high-load structural connections rather than general assembly. The JG9HC27 is a Grade 9 screw in 5/8-11 x 2 inch, so if a drawing calls for Grade 8 in that size this exceeds it, but check with the engineer before substituting the other way.
4) What is the Metallics part number for the 5/8-11 x 2 Grade 9 hex cap screw?
Order it as Metallics JG9HC27. That is the manufacturer part number for the 5/8-11 x 2 inch Grade 9 hex cap screw in the 25-piece jar.
5) Is a Grade 9 hex cap screw right for electrical equipment mounting and strut work?
It is sold as an electrical fastener, and a 5/8-11 x 2 inch hex cap screw is a common size for heavy equipment bases, transformer pads, busway supports, and heavy strut connections. For light fixture hanging or small channel nuts, a 1/2-13 or 3/8-16 screw is the usual call and Grade 9 is more fastener than the connection needs.
