Metallics JLW179 – Frequently Asked Questions
1) Are these Metallics lock washers plated for corrosion resistance?
They are steel with a zinc plating, which gives basic corrosion protection for dry indoor electrical work, strut and channel assemblies, panel and enclosure mounting, and general equipment anchoring. Zinc plated steel is not the choice for sustained wet, coastal, or chemically aggressive exposure, where stainless would be specified.
2) How many 9/16 split lock washers come in a jar of Metallics JLW179?
One hundred washers per jar, and the pack is a jar rather than a box or bag, which is what makes it practical to keep on a service truck or at a bench without the contents spilling. Jar weight is listed at 13.17 lbs.
3) Is a split lock washer or a flat washer the right choice for bolted electrical equipment?
Different jobs. A split lock washer like the JLW179 is a helical spring washer whose sharp split ends dig into the nut and the joint surface to keep the fastener from backing out under vibration. A flat washer spreads load and protects the surface but does nothing against loosening. On equipment that vibrates, such as motors, transformer frames, and strut mounted gear, many installers use both: a flat washer against the material, then the split lock under the nut.
4) What is the exact part number and brand for these 9/16 split lock washers?
Brand is Metallics, part number JLW179, described as 9/16 split lock washer, steel zinc, jar of 100. That MPN is what to quote on a purchase order so you get the 9/16 size rather than an adjacent diameter in the same jar line.
5) How much space does a jar of Metallics 9/16 lock washers take on a shelf or in a truck bin?
The jar measures 3 inches long by 3 inches wide and 2.7 inches high, so it drops into a standard small parts bin or van drawer alongside other fastener jars.
6) Where are Metallics JLW179 lock washers made?
Country of origin is China. Buyers on federally funded or domestic-preference jobs should note that for their submittal paperwork.
