Metallics JG9HC16 – Frequently Asked Questions
1) What thread size and length is the Metallics JG9HC16 hex cap screw?
The JG9HC16 is a 3/8-16 x 2 inch hex cap screw. The 3/8-16 call-out means a 3/8 inch nominal diameter with 16 threads per inch, which is the UNC coarse thread for that diameter, so it mates with standard 3/8-16 nuts and tapped holes. Overall length is 2 inches under the head.
2) How many bolts come in a jar of Metallics JG9HC16?
Each jar holds 25 of the 3/8-16 x 2 inch Grade 9 hex cap screws. The jar pack is the ordering unit, so a job needing 60 bolts takes three jars.
3) What does Grade 9 mean on a hex cap screw, and when would I use one instead of a Grade 5 or Grade 8?
Grade 9 is a higher strength class than Grade 5 or Grade 8, so the JG9HC16 is the choice where a 3/8 inch bolted joint is carrying heavy shear or vibration loads and you do not want to step up to a larger diameter. For general-purpose electrical mounting and light structural work, a Grade 5 fastener of the same 3/8-16 x 2 size is the usual spec. Note that higher grade bolts should be torqued to the grade, not to a generic value, and they should be paired with a nut of matching or higher strength.
4) Is the JG9HC16 bolt supplied with nuts or washers?
No. The jar contains 25 of the 3/8-16 x 2 inch Grade 9 hex cap screws only. Order 3/8-16 nuts and 3/8 inch washers separately, and match the nut to the bolt grade so the nut is not the weak point in the joint.
5) Will a 2 inch long 3/8-16 bolt be long enough for my strut and bracket stack-up?
The JG9HC16 gives 2 inches of length under the head. Add up your material thickness plus washers and leave enough thread protruding through the nut to engage it fully; 2 inches typically covers a strut channel plus a bracket and hardware, but a thicker built-up stack needs a longer bolt in the same 3/8-16 thread.
6) Can I drive the JG9HC16 with a standard wrench or do I need a special bit?
It is a hex cap screw, so it drives with an open end, box end, or socket wrench on the head. No specialty bit or internal drive is involved.
