Metallics JSLW921 – Frequently Asked Questions
1) What bolt size does the Metallics JSLW921 split lock washer fit?
The JSLW921 is a 5/8 inch split lock washer, so it goes under a nut or bolt head on 5/8 inch diameter threaded fasteners. Pair it with 5/8-11 or 5/8-18 hardware depending on your thread pitch.
2) Are these 5/8 lock washers stainless steel, and can they be used outdoors or in damp locations?
Stainless steel, which is why they get specified for outdoor strut runs, rooftop equipment, wet locations, and coastal or washdown areas where a plain or zinc washer would rust and seize. Keep the washer, bolt, and nut all stainless to avoid mixing metals at the joint.
3) How many washers come in a jar of Metallics JSLW921?
100 pieces per jar. It ships as a jar pack rather than loose count, so one order unit gets you the full 100 count of 5/8 split lock washers.
4) Should I use a split lock washer or a flat washer on 5/8 inch bolted connections?
Two different jobs. The JSLW921 is a split lock (helical spring) washer, so it puts spring tension into the joint and bites the nut and the mating surface to resist loosening under vibration, which is what you want on motor mounts, transformer pads, generator frames, and strut hardware. A flat washer only spreads the load and protects the surface; it does nothing about vibration. On soft or oversized holes, many installers use a flat washer against the material and the split lock under the nut.
5) What does a jar of 100 Metallics 5/8 split lock washers weigh for shipping or a parts kit?
3.32 lbs for the full jar, in a container measuring 3 x 3 x 3.6 inches. Useful if you are building out a service truck bin or pricing freight on a bulk fastener order.
6) Can I reuse split lock washers when I break a connection apart?
No. Once a split lock washer has been torqued it has taken a set and the spring action is no longer reliable, so pull a fresh one from the jar on reassembly. That is the reason these are sold 100 to a jar rather than individually.
