Metallics JLWX9 – Frequently Asked Questions
1) What is the difference between an external tooth lock washer and a split ring lock washer?
An external tooth washer like the JLWX9 has teeth around its outer edge that bite into the bolt head or nut face and the mounting surface, spreading the anti-rotation grip over a wide circle. A split ring washer puts its spring load on a single cut edge. External tooth is the one to reach for on sheet metal enclosures, strut, and panel work where you want bite over a larger bearing area; it also helps scrape through paint or zinc for a bonding path. Split ring is more common in structural bolted joints.
2) Are these 1/2 inch lock washers plated for corrosion resistance?
Yes. They are steel with a zinc plating, which is the standard finish for indoor and protected electrical, plumbing, and HVAC work. For sustained outdoor or wet exposure, stainless would be the better call.
3) How many washers come in a jar of Metallics JLWX9?
100 pieces per jar. It ships as a jar pack, which is the form most electricians keep on the van or in a shop bin rather than a loose bulk box.
4) What part number should I order for a 1/2 inch Metallics external tooth lock washer?
Order Metallics JLWX9. That is the manufacturer part number for the 1/2 inch external tooth lock washer in zinc plated steel, supplied in a 100-piece jar.
5) How much shelf or bin space does a 100-count jar of 1/2 inch tooth lock washers take up?
The jar measures 3 x 3 x 2.15 inches and weighs 0.39 lbs, so it drops into a standard small-parts bin or a van drawer without repacking.
