Metallics JSLW8 – Frequently Asked Questions
1) What bolt size do the Metallics JSLW8 split lock washers fit?
The JSLW8 is a 5/16 inch split lock washer, so it seats under a nut or bolt head on 5/16 inch threaded fasteners. Split lock washers don't care about thread pitch, only the shank diameter, so it works with both coarse and fine 5/16 hardware.
2) Are these 5/16 lock washers stainless steel or plated?
Stainless steel, not plated carbon steel. That matters if you're mounting strut, conduit hangers, or equipment where you already ran stainless bolts, or anywhere damp, since a zinc-plated washer paired with stainless hardware is the part that rusts first.
3) How many washers come in a jar of Metallics JSLW8?
Each jar holds 100 of the 5/16 stainless split lock washers, packaged as a jar rather than a loose bag, which keeps them contained on a cart or in a van bin. Total shipping weight for the jar is 0.44 lbs.
4) Should I use a split lock washer or a flat washer under my 5/16 nuts?
They do different jobs. A split lock washer like the JSLW8 bites into the nut and the mating surface to resist loosening from vibration, which is why it goes on motor mounts, transformer and panel hardware, and strut connections. A flat washer spreads load and protects a soft or slotted surface but does nothing against vibration. On sheet metal or soft material, many installers stack a flat washer against the surface with the split lock on top of it under the nut.
5) Do these 5/16 split lock washers meet a dimensional standard?
Metallics lists the JSLW8 to ANSI dimensions, so the inside diameter, outside diameter, and section thickness follow the standard 5/16 helical spring lock washer sizing. In practice that means it interchanges with any other ANSI-dimensioned 5/16 split lock washer already on the job.
6) Are these stainless lock washers meant for electrical work or general mechanical use?
Both. Metallics lists the JSLW8 for the electrical, plumbing, heating and air conditioning trades, so it's the same washer you'd pull for conduit strap hardware, panel and enclosure mounting, pipe hanger rod, and equipment anchoring. Nothing about it is electrical-specific beyond how it's catalogued by the trade that buys it.
