Metallics JG9HC26 – Frequently Asked Questions
1) What does Grade 9 mean on this 5/8-11 bolt, and is it stronger than a Grade 8?
Grade 9 is a higher strength class than the common Grade 5 and Grade 8 structural fasteners, so the JG9HC26 is specified where a Grade 8 is not enough. Because the strength comes from heat treatment, don't weld it, re-heat it, or bend it, and use a nut rated to match the bolt rather than a plain commercial nut.
2) Do the Metallics JG9HC26 bolts come with nuts and washers?
No. The jar contains 25 hex cap bolts only, so order 5/8-11 nuts and 5/8 washers separately. With a Grade 9 bolt, match the nut to the bolt's strength class or you lose the benefit of the higher grade.
3) What hole size do I need to drill for a 5/8-11 hex cap bolt?
A 5/8 inch nominal bolt wants a clearance hole slightly over 5/8 inch, commonly 11/16 inch for a standard fit. If you're tapping instead of through-bolting, a 5/8-11 tapped thread is cut with a 17/32 inch drill.
4) What is the Metallics part number to order for the Grade 9 5/8-11 x 1-1/2 hex cap bolt?
Order Metallics JG9HC26. That part number covers the 5/8-11 x 1-1/2 Grade 9 hex cap bolt in the 25 piece jar, and it is the only configuration under that number.
5) Can I use these bolts outdoors or in a damp location?
Treat the JG9HC26 as a bare high strength steel fastener and keep it in dry, protected service. High grade heat treated bolts like this are not plated for corrosion duty and are susceptible to hydrogen embrittlement if galvanized or electroplated, so for wet or exterior work use a fastener specified for that exposure, such as stainless or hot dip galvanized hardware in the grade your connection calls for.
