Metallics JLW172D – Frequently Asked Questions
1) What bolt size does the Metallics JLW172D split lock washer fit?
The JLW172D is a 1/4 inch split lock washer. Its inside diameter runs 0.250 to 0.260 inches and the outside diameter is 0.487 inches, so it seats on 1/4-20 or 1/4-28 bolts and screws without hanging up on the threads.
2) Is a split lock washer or a flat washer the right choice for electrical mounting hardware?
They do different jobs. The JLW172D is a split lock washer, meaning the ring is cut and sprung so it bites the nut and the mounting surface and resists loosening from vibration, which is what you want on panel mounting, strut, transformer and motor hardware. A flat washer only spreads load over soft or oversized holes and does nothing about vibration. On sheet metal or slotted channel it is common to use both: flat against the material, lock washer under the nut.
3) What finish and material are these 1/4 inch lock washers, and can I use them outdoors?
Steel with a zinc chromate finish. That plating handles indoor, dry, and normally protected outdoor conditions, but it is not stainless. For coastal, wash-down, or continuously wet locations, specify a stainless split lock washer instead.
4) Are these lock washers made in the USA for jobs with domestic sourcing requirements?
Yes. The JLW172D is a domestic lockwasher with country of origin listed as the United States, which is what public agency and institutional buyers with domestic preference language on the spec need to see.
5) How are the Metallics 1/4 inch lock washers packaged for a service truck?
They ship as a jar of 100, which is the format most electricians and MRO stockrooms want on the shelf or in a truck bin rather than loose bulk. Total packed weight is 0.26 lbs.
