Metallics JMLW12SS – Frequently Asked Questions
1) Are these M12 lock washers stainless steel or plated steel?
Stainless steel. That matters if you're mounting strut, enclosures, or conduit supports outdoors, in a wash-down area, or anywhere a zinc-plated washer would rust and seize the nut. Match it with stainless bolts and nuts so you don't create a dissimilar-metal joint.
2) Should I use a split lock washer or a flat washer for an M12 bolted connection?
They do two different jobs. A split lock washer like the JMLW12SS bites into the nut and the mating surface to resist loosening from vibration, which is why it shows up on motor mounts, transformer bases, and strut hardware. A flat washer spreads load and protects the surface but does nothing against vibration. On soft or slotted material, many installers run both: flat against the material, split lock under the nut.
3) Can I use these stainless lock washers on outdoor electrical equipment grounding and mounting hardware?
Yes, for mounting and clamping duty on outdoor electrical gear, which is what this washer is catalogued for on the electrical side. Stainless holds up in weather where plated steel corrodes. One caution: a split lock washer is not a listed grounding or bonding washer, so don't rely on it to make or maintain a ground path, use the bonding hardware specified for that connection.
4) Is the Metallics JMLW12SS a dimensionally standard M12 lock washer?
It is an ANSI-referenced M12 split lock washer in stainless, so the bore and section follow standard M12 washer geometry and it will seat under any standard M12 hex nut or bolt head. Country of origin is China.
