Metallics JLWI1 – Frequently Asked Questions
1) What screw size does the Metallics JLWI1 internal tooth lock washer fit?
The JLWI1 is a #4 internal tooth lock washer, so it pairs with #4 machine screws and small sheet metal screws. The teeth face inward toward the bore, which keeps them hidden under the screw head on finished plates and cover screws.
2) Internal tooth or external tooth lock washer for a device plate screw?
Use an internal tooth washer like the #4 JLWI1 when the washer sits under a screw head on a visible surface. The teeth bite inside the bore against the screw head and the mating surface, so they do not mar the outer ring of material around the hole. External tooth washers grip over a wider circle and hold better on soft or oversized holes, but the teeth show and can scratch a finished plate.
3) Are these steel washers plated for corrosion resistance?
Material is zinc plated steel. That is fine for dry indoor electrical work, panel and device assembly, and general interior MRO. For wet locations, exterior, or coastal exposure, specify stainless rather than zinc plated steel.
4) Do these lock washers follow ANSI sizing?
The JLWI1 is built to ANSI dimensional sizing for a #4 internal tooth lock washer, so it interchanges with other ANSI-dimensioned #4 tooth washers in an existing assembly.
5) How many Metallics JLWI1 lock washers come in a jar?
100 pieces per jar. The pack type is a jar rather than a bag, which is why it is practical to keep on a service van or in a parts bin without the washers spilling. Total jar weight is listed at 0.07 lbs.
6) Will a jar of these #4 washers fit in a standard parts bin drawer?
The jar measures 3 x 3 x 2.15 inches, so it drops into most small parts bins and van drawer organizers without decanting.
