Metallics JLWX5M – Frequently Asked Questions
1) How many washers come in a jar of Metallics JLWX5M?
They ship 1000 pieces to a jar. The jar itself is the stock pack, which is why it suits a service van or a shop bin rather than a one-off repair.
2) Are these washers plated for corrosion resistance?
Yes. The JLWX5M is steel with a zinc plating, which gives it basic corrosion resistance for indoor and protected locations. For wet, exterior, or chemically aggressive locations, go to a stainless washer instead.
3) External tooth or internal tooth lock washer, which should I use?
The JLWX5M is an external tooth type. Teeth on the outside diameter give more bite area under the fastener head and the grip is visible, so it is the usual choice where the bearing surface is wide and appearance under the head does not matter. Internal tooth washers hide the teeth under the head and are preferred for a cleaner look or where the mating surface is narrow. Both are lock washers, so either resists loosening from vibration.
4) Will a #10 external tooth lock washer bite through paint for a ground bond?
External tooth lock washers cut into the mating surface by design, which is why electricians reach for them on grounding and bonding screws. Use the JLWX5M as the vibration lock under a #10 ground screw; where the code requires a listed bonding method, follow the listed device or lug rather than relying on the washer alone.
5) What does the jar of JLWX5M washers weigh and how much shelf space does it take?
A jar runs 0.4 lbs and measures 3 x 2.15 x 3 inches, so it drops into a standard small-parts bin or van drawer without repacking.
6) Do I need a flat washer with these lock washers?
On soft or slotted material, yes, pair the external tooth washer with a flat washer underneath to spread load and keep the teeth from chewing through. Flat washers are a separate item; a jar of JLWX5M contains lock washers only.
