Metallics JG9HC28 – Frequently Asked Questions
1) What thread size and length is the Metallics JG9HC28 hex cap bolt?
It's a 5/8-11 x 2-1/2 inch hex cap bolt. The 5/8-11 means a 5/8 inch diameter shank with 11 threads per inch, which is the standard UNC coarse pitch for that diameter, so it takes any standard 5/8-11 nut. The 2-1/2 inch figure is the shank length under the head, not the overall length including the head.
2) What does Grade 9 mean on a hex cap bolt, and when do I need it instead of Grade 5 or Grade 8?
Grade 9 is a higher strength class than Grade 5 or Grade 8 structural fasteners, used where joint loads or vibration would pull a lower grade loose. The JG9HC28 is a Grade 9 hex cap bolt in 5/8-11 x 2-1/2. If your drawing or equipment manual calls for Grade 5 or Grade 8, a Grade 9 bolt exceeds that strength requirement; if the spec calls out Grade 9 specifically, do not substitute down, because the joint was sized around the higher clamp load.
3) How many bolts come in the Metallics JG9HC28 jar?
25 bolts per jar. Metallics packages this 5/8-11 x 2-1/2 Grade 9 hex cap bolt in jar packaging, so you're buying a sealed count of 25 rather than loose bin stock, which is what you want if you're pulling fasteners on a service truck and need the count to stay intact.
4) What size wrench or socket do I need for a 5/8-11 hex cap bolt?
A 5/8-11 hex cap screw takes a 15/16 inch wrench or socket across the flats, which is the standard head size for that diameter in inch hex cap screws. The JG9HC28 is the 2-1/2 inch length in that diameter.
