Metallics JBHC42G – Frequently Asked Questions
1) What size wrench or socket do I need for these 5/16-18 galvanized hex bolts?
Head width across flats measures 0.484 to 0.500 inch on the JBHC42G, which is a 1/2 inch wrench or socket. Standard hex head, so a nut driver, open end, or 1/2 inch socket on a cordless impact all work.
2) Are these galvanized bolts okay for damp or outdoor electrical work?
The JBHC42G is galvanized steel, so it holds up better than plain steel in damp locations, outdoor strut runs, and unheated spaces. For continuous saltwater exposure or harsh chemical service, stainless is the better call. Galvanized hardware is the normal choice for exterior strut, conduit supports, and equipment mounting.
3) Is a 3/4 inch long bolt enough to mount into strut channel or a channel nut?
A 3/4 inch 5/16-18 bolt is the common length for strut channel work: it clears the channel lip and a bracket of normal thickness while engaging a spring nut or channel nut fully. If you are stacking a thick backplate or two brackets, step up in length. The JBHC42G threads are 18 TPI, which matches 5/16-18 strut and spring nuts.
4) How many Metallics JBHC42G bolts come in a jar, and can I get a smaller quantity?
These ship 100 bolts to a plastic jar, and 100 count is the order minimum. Jar packaging keeps them together on the truck and on the gang box rather than loose in a bag. Other sizes and quantities in the BHC and JBHC range can be sourced by request.
5) Do the JBHC42G bolts come with nuts and washers?
No. The jar holds 100 hex bolts only, 5/16-18 x 3/4 galvanized. Order matching 5/16-18 hex nuts and 5/16 flat or lock washers separately, in a galvanized finish so you are not mixing coatings on the same joint.
6) Where are Metallics JBHC42G hex bolts made?
Country of origin on the JBHC42G is China. For jobs with domestic-sourcing requirements on fasteners, confirm the origin language in your spec before committing the submittal.
7) What is the shipping weight of a 100-count jar of JBHC42G bolts?
A full jar runs 2.57 lbs, with the packaged jar at roughly 3 x 3 x 3.6 inches. Light enough to keep several sizes on the truck without eating payload.
