Metallics JSBH186 – Frequently Asked Questions
1) Is the JSBH186 bolt stainless, and what grade?
316 stainless steel, the molybdenum-bearing grade that holds up better than 304 against chlorides, so it's the one to reach for on coastal, wastewater, pool chemical, and roadway de-icing exposures.
2) How does the Metallics JSBH186 come packaged, and how many bolts do I get?
They ship 100 bolts to a jar, which is the pack type for this item. That's a shop or truck-stock quantity rather than a bulk box, handy for an electrician keeping a run of 5/16-18 x 3-3/4 stainless on the van.
3) Do I need to order nuts and washers separately for these 5/16-18 stainless bolts?
Yes. The JSBH186 is bolts only, 100 to a jar, with no nuts or washers in the pack. Order matching 5/16-18 nuts and 5/16 flat and lock washers, and keep them in 316 stainless too so you don't set up galvanic corrosion or lose the corrosion rating you paid for at the joint.
4) Can I use 316 stainless bolts outdoors and in wet electrical installations?
That's what they're for. Metallics catalogs the JSBH186 as electrical supply hardware, and 316 stainless is the usual specification for exterior strut, enclosure mounting, and rooftop or marine-adjacent work where plated steel would rust out. Note that stainless is not a high-strength grade the way a Grade 5 or Grade 8 plated bolt is, so for heavy structural load paths check what the drawing calls for.
5) What part number do I order for the Metallics 5/16-18 x 3-3/4 stainless hex bolt?
JSBH186 is the Metallics part number, and it's the only configuration sold under it: 5/16-18 x 3-3/4, hex head, 316 stainless, 100 per jar. There's no finish or length choice to specify.
6) Will stainless bolts gall when I run the nut down?
316 stainless is prone to thread galling, especially with a stainless nut run fast with an impact driver. Run them down slowly, or use an anti-seize on the threads. It's the one handling quirk with stainless fasteners that catches people who normally set plated hardware.
