Metallics JLWX5 – Frequently Asked Questions
1) What screw size does the Metallics JLWX5 external tooth lock washer fit?
The JLWX5 is a #10 external tooth lock washer, so it pairs with #10 machine screws and bolts. Material is zinc plated steel. It ships as a jar of 100, which is the usual way an electrician stocks a truck for device screws, ground screws and strap hardware.
2) External tooth or internal tooth lock washer, which should I use on a panel screw?
External tooth is what the JLWX5 gives you: the teeth sit outside the screw head diameter, so they bite on a larger circle and resist loosening better under vibration. That also means the teeth stay visible under the head, which is why they are the common choice for bonding and grounding connections where you want the plating scraped through to bare metal. Internal tooth hides the teeth under the head and is the neater looking option on finished trim or where the screw head is small.
3) Are these washers suitable for grounding and bonding connections in a panel?
Yes. An external tooth lock washer in zinc plated steel is the standard star washer used under a #10 ground screw or bonding lug to cut through paint and plating for metal to metal contact. Metallics lists the JLWX5 for the electrical, plumbing, heating and air conditioning trades.
4) Will zinc plated steel star washers hold up outdoors or in a wet location?
The JLWX5 is zinc plated steel, which is a mild corrosion coating meant for dry indoor and protected work. For damp, coastal or chemically exposed installs, specify a stainless external tooth washer in the same #10 size instead.
5) Do Metallics JLWX5 washers meet ANSI dimensional sizing?
Metallics lists the JLWX5 to ANSI for the #10 external tooth lock washer, so the inside diameter, outside diameter and thickness follow the standard pattern and the washer interchanges with other ANSI #10 star washers already in your stock.
