Metallics JSLW3 – Frequently Asked Questions
1) What screw size does the Metallics JSLW3 split lock washer fit?
The JSLW3 is a #4 split lock washer, so it pairs with #4 machine screws and bolts. Ordering part number JSLW3 gets you that size; a #6 or #8 screw needs a different washer.
2) Are the JSLW3 lock washers stainless steel or plated steel?
Stainless steel. That makes them a reasonable choice for damp locations, exterior enclosures, and corrosive environments where a zinc-plated washer would rust out. Pair them with stainless #4 screws to avoid mixing dissimilar metals.
3) Should I use a split lock washer or a flat washer under a #4 screw in a panel?
Different jobs. A split lock washer like the JSLW3 bites into the nut face and the mating surface to resist loosening from vibration, which is why it shows up on device terminals, enclosure grounding hardware, and panel assemblies. A flat washer only spreads the load and will not stop a screw from backing out. If you need both load spreading and vibration resistance, stack a flat washer against the work surface and the split lock under the fastener head or nut.
4) Can I use the Metallics JSLW3 stainless washers on outdoor electrical enclosures?
Yes, the stainless steel construction holds up in wet and outdoor locations where plated steel washers corrode and seize. Keep the whole fastener stack stainless so the washer is not the only corrosion resistant piece in the joint.
5) How many #4 split lock washers come in a jar of JSLW3?
Each jar holds 100 pieces, packaged in a jar rather than a bag or box, which is the usual format for MRO cribs and service vans where small fasteners get scooped out by hand.
6) Is the JSLW3 washer sized to an ANSI standard?
The #4 split lock washer is built to ANSI dimensional standards, so it interchanges with other ANSI #4 split lock washers already in your hardware bins.
