Metallics JG9HC31 – Frequently Asked Questions
1) What thread size and length is the Metallics JG9HC31 hex cap screw?
It's a 5/8-11 x 4 inch hex cap screw. The 5/8-11 callout is the coarse (UNC) thread pitch for 5/8 inch diameter, so it mates with standard 5/8-11 nuts and tapped holes, and the 4 inches is shank length under the head. Grip plus nut has to fall inside that 4 inches, so stack your plate thicknesses before ordering.
2) Is a Grade 9 bolt stronger than the Grade 5 or Grade 8 bolts I normally use?
Yes. The JG9HC31 is a Grade 9 hex cap screw, which sits above both Grade 5 and Grade 8 in tensile strength. If the drawing calls for Grade 5 or Grade 8, a Grade 9 satisfies the strength requirement, but it does not work the other way around: don't substitute a Grade 5 where Grade 9 is specified. Grade 9 fasteners are also typically used with a matching high-strength nut rather than a standard grade nut, so size the nut to the bolt.
3) How many bolts come in the Metallics JG9HC31 pack?
Twenty-five bolts, supplied in a jar. That's the packaging unit for this item, so a strut or framing job needing fifty 5/8-11 x 4 bolts takes two jars.
4) Does the JG9HC31 bolt come with nuts and washers?
No. It's bolts only, 25 hex cap screws in a jar. Nuts and washers are separate line items, and for a Grade 9 bolt you'll want a nut rated to match rather than a standard grade nut.
5) What is the Metallics part number for the 5/8-11 x 4 Grade 9 hex cap screw?
Metallics JG9HC31. That's the manufacturer part number to quote or reorder against, and it covers the 5/8-11 x 4 Grade 9 hex cap screw in the 25 piece jar.
