Metallics JLWI3SS – Frequently Asked Questions

1) What is the difference between an internal tooth and an external tooth lock washer, and when should I use internal?
On an internal tooth washer the teeth face inward, toward the bolt, so they are hidden under the screw head once tightened. That makes it the choice when you want a cleaner finished look or when the mating surface is a painted or plated panel you would rather not scar visibly. External tooth washers put the teeth on the outer rim for more bite surface, better suited to larger heads and heavier clamp loads. The Metallics JLWI3SS is the internal tooth type in #6.
2) Are these #6 lock washers OK for outdoor or damp locations?
They are stainless steel, so corrosion resistance is better than plain or zinc plated steel, which is why they get used on exterior and damp-location work. Keep in mind stainless hardware against dissimilar metals can still set up galvanic corrosion, so pair them with stainless or compatible screws.
3) How many washers come in the jar, and is that enough for a panel trim-out?
Each jar holds 100 pieces of the #6 internal tooth lock washer. For a typical panel or device trim-out that covers the job and leaves stock on the truck; the jar is the pack type, so you are buying by the container, not loose by the piece.
4) Why use a tooth lock washer instead of a split ring washer on vibrating equipment?
A toothed washer presents multiple teeth that bite into the joint faces all the way around, which resists the rotation that vibration and thermal cycling cause. A split ring bites at two points only. The Metallics #6 internal tooth washer is aimed at exactly that duty, with HVAC equipment and ductwork connections and industrial equipment assembly among its listed uses.
5) Do these Metallics washers meet ANSI dimensional standards?
Yes, the #6 internal tooth lock washers are manufactured to ANSI standards for dimensional consistency, which matters when you are specifying hardware for a submittal or standardizing fastener stock across a facility.
6) What is the Metallics part number and country of origin for the #6 stainless internal tooth lock washer jar?
Order it as Metallics JLWI3SS. Country of origin is China. Shipping weight on the jar is 0.1 lbs, with the container listed at 3 in length, 3 in width and 2.15 in height.
