Metallics JLWX4 – Frequently Asked Questions
1) External tooth or internal tooth lock washer - which should I use on a bonding connection?
External tooth is the one you want where the teeth need to bite into a painted or plated surface. The teeth sit outside the screw head on the JLWX4, so they spread the bite over a larger diameter and cut through finish for a better metal-to-metal path. Internal tooth washers hide the teeth under the screw head, which looks cleaner but bites a smaller circle and grips less on a wide flange or a sheet metal panel.
2) What material and finish are the Metallics #8 external tooth lock washers?
Zinc plated steel. The plating gives basic corrosion resistance for dry indoor work, panels, enclosures and device boxes. For wet, outdoor or corrosive locations you want stainless rather than zinc plated steel.
3) How many washers come in a jar of Metallics JLWX4?
100 pieces per jar. It ships as a jar pack, which is the format most electricians keep on the truck or on the shop bench for restock - the whole jar of 100 weighs 0.09 lbs.
4) Are these washers only for electrical work, or can I use them on HVAC and plumbing jobs too?
The JLWX4 is stocked for the electrical, plumbing, heating and air conditioning trades. It is a general purpose #8 external tooth lock washer, so the same jar covers device and panel screws, control wiring terminals and equipment mounting on mechanical work.
5) Do the Metallics JLWX4 lock washers meet ANSI dimensions?
Metallics lists the JLWX4 to ANSI. For a maintenance or institutional spec that calls for ANSI dimensioned #8 external tooth lock washers, that is the reference on this part.
6) Where is the Metallics JLWX4 washer made?
Country of origin is listed as multiple, so the jars are sourced from more than one manufacturing country. If your job carries a domestic sourcing requirement, this is not the part that satisfies it.
