Metallics JLWX7 – Frequently Asked Questions
1) What size bolt does the Metallics JLWX7 external tooth lock washer fit?
The JLWX7 is a 5/16 inch external tooth lock washer, so it goes on 5/16 inch bolts, screws, and threaded rod. Order it by part number JLWX7.
2) Should I use an external tooth lock washer or a split lock washer for a ground bonding connection?
External tooth washers like the JLWX7 spread their bite across many teeth on the outside diameter, which cuts through paint or coating and gives a wider anti-rotation grip under a bolt head or nut. A split ring bears on one spot only. That is why the external tooth style is the one commonly used on panel and enclosure bonding hardware, and Metallics lists this washer for electrical, plumbing, heating and air conditioning work.
3) Is the Metallics JLWX7 washer zinc plated steel?
Yes, it's steel with a zinc plating. That suits dry indoor and protected work; for wet or corrosive exposure a stainless washer is the better call.
4) How many washers come in a jar of Metallics JLWX7?
Each jar holds 100 of the 5/16 inch external tooth lock washers. The jar packaging is the shop-cart format, so one jar stocks a service truck bin rather than a single job.
5) How much does a jar of 100 Metallics 5/16 external tooth lock washers weigh and how big is the jar?
The packed jar weighs 0.15 lbs and measures 3 x 3 x 2.15 inches, small enough to sit in a van drawer or a hardware organizer with the rest of your fastener stock.
