Metallics JLW171D – Frequently Asked Questions
1) Is the JLW171D lock washer plated for corrosion resistance?
It's zinc plated steel. The zinc coating handles normal dry indoor use, panels, enclosures, and boxes. For wet locations, washdown areas, or outdoor exposure, step up to a stainless split lock washer instead.
2) How many #10 lock washers come in a jar of Metallics JLW171D?
100 washers per jar. The jar pack is what makes it a van-stock item, a screw-top container you can pull from on a ladder without spilling the rest.
3) Should I use a split lock washer or a star washer under a ground screw?
A split lock washer like the #10 JLW171D works by spring tension, the open coil digs into the nut face and the joint face to resist back-off from vibration. An external tooth star washer bites through coating and is the choice when you also want it to scrape paint for a bonding path. For a clean, already-bare ground lug or a tapped hole in a box, the split washer is the normal pick.
4) Are these #10 lock washers made in the USA?
Yes, the JLW171D is US made zinc plated steel, which matters if you're on a federally funded or Buy American spec job and have to document fastener origin.
5) Can I use the JLW171D with a #10 flat washer on the same screw?
Yes, and that's the usual stack on soft or slotted material: flat washer against the surface to spread load, split lock washer between the flat washer and the nut or screw head. Order the #10 flat washer separately, the JLW171D jar contains split lock washers only.
