Metallics JMLW05 – Frequently Asked Questions
1) How many M5 lock washers come in a jar of Metallics JMLW05?
100 washers per jar, packed in a jar rather than a bag or box. The jar weighs 0.13 lbs total. That quantity suits panel and device work where you are burning through M5 hardware on a single build rather than buying a bulk box.
2) Are Metallics M5 split lock washers steel or stainless?
Carbon steel with a zinc finish, not stainless. Zinc plating gives basic corrosion resistance for dry indoor electrical work. For wet locations, exterior enclosures, or anywhere there is chemical exposure, specify a stainless M5 lock washer instead.
3) What is a split lock washer used for in electrical panel and conduit work?
A split lock washer is a steel ring cut and sprung open so it loads the joint and bites into the nut and the mating surface, resisting loosening from vibration. The JMLW05 is intended for electrical, plumbing, heating and air conditioning work, so typical uses are M5 machine screws in enclosures, device mounting, strut hardware, and equipment where vibration would otherwise back a fastener out. It is not a bearing or load-spreading washer; if you need to spread load on soft material, add a flat washer under it.
4) Where are Metallics JMLW05 washers made?
Country of origin on the JMLW05 M5 lock washer is listed as multiple, meaning Metallics sources it from more than one country. If a job carries a domestic-source requirement, this is not the part to spec.
