Metallics JMLW08 – Frequently Asked Questions
1) What bolt size does the Metallics JMLW08 split lock washer fit?
The JMLW08 is a metric lock washer sized for M8 bolts and screws. It will not seat correctly on imperial 5/16 inch hardware, which is the closest inch size but a different diameter, so stay with M8 threaded fasteners.
2) Are these M8 lock washers plated for corrosion resistance?
They are steel with a zinc finish. That plating handles normal indoor panel, conduit strut, and mechanical room work. For sustained wet, coastal, or chemical exposure, specify stainless rather than zinc plated steel.
3) How many M8 split lock washers come in a jar of Metallics JMLW08?
One hundred washers per jar, packed in a jar rather than a bag or box, which is why it stacks on a shelf and pours without spilling on a service truck. Jar weight is 0.43 lbs.
4) What does a split lock washer actually do under a nut, and do I still need a flat washer?
A split lock washer bites into the nut face and the mating surface as it is torqued, resisting loosening from vibration. It does not spread load, so where the material is soft or the hole is oversized you still want a flat washer under the split washer. The JMLW08 covers the anti-vibration half of that stack in M8.
5) Are Metallics M8 lock washers suitable for electrical and HVAC work, or just general fastening?
They are catalogued for the electrical, plumbing, heating and air conditioning trades, which is the typical use: strut and channel hardware, panel and enclosure mounting, hanger rod and clamp assemblies using M8 threads.
6) How much shelf space does a jar of JMLW08 washers take on a van or stockroom shelf?
The jar measures 3 in length, 3 in width, and 2.15 in height, so it fits a standard small-parts bin or drawer without repacking.
