Metallics JSLW12 – Frequently Asked Questions
1) What screw or bolt size does the Metallics JSLW12 split lock washer fit?
The JSLW12 is sized for a #12 fastener, with a stated fit of 13/64 inch bolt size. That is the inside diameter it seats on, so it pairs with #12 machine screws, sheet metal screws, and threaded rod of that nominal size. If you are fastening 1/4-20 or 10-32 hardware, this is the wrong size washer.
2) Are these split lock washers stainless steel or plated steel?
Stainless steel. That matters on outdoor enclosures, wet locations, rooftop equipment, and anywhere a zinc plated washer would rust and seize the screw. Keep stainless washers with stainless fasteners so you are not mixing dissimilar metals on the same joint.
3) How many washers come in a jar of Metallics JSLW12?
100 pieces, packaged in a jar rather than a bag or box, which is what you want on a service van or a shop bench where you are pulling a handful at a time. Jar weight is listed at 0.16 lbs.
4) Should I use a split lock washer or a flat washer on a panel ground screw?
They do different jobs. A split lock washer like the JSLW12 is a spring type washer, the split ends bite into the nut face and the joint surface to resist loosening from vibration. A flat washer only spreads load and does nothing against back-off. On equipment that vibrates, HVAC units, motor connections, panel grounds, the split lock is the one that keeps the screw tight. Many installers use both: flat washer against the material, split lock under the nut.
5) Will a #12 split lock washer work with 1/4 inch strut hardware?
No. The JSLW12 seats on a 13/64 inch bolt size, which is #12 nominal. Strut channel nuts and hangers are normally 1/4-20 or 3/8-16, so a #12 washer will not seat under that head correctly. Order the matching 1/4 or 3/8 split lock washer for strut work.
6) Can I use these Metallics washers on plumbing and HVAC work, or are they electrical only?
Not electrical only. The JSLW12 is listed for the electrical, plumbing, heating and air conditioning trades, so the same jar covers panel and device work, strut and hanger assemblies, and mechanical equipment fastening.
7) Do these washers meet a dimensional standard for #12 hardware?
The JSLW12 split lock washer is built to ANSI dimensions, so it interchanges with other ANSI dimensioned #12 split lock washers in your bin. Country of origin is listed as multiple.
