Metallics JLWI9 – Frequently Asked Questions
1) What size bolt does the Metallics JLWI9 internal tooth lock washer fit?
The JLWI9 is a 1/2 inch internal tooth lock washer, so it is sized for 1/2 inch bolts, screws and studs. The teeth sit on the inside diameter, biting the bolt shank side rather than showing at the outer edge.
2) Should I use an internal tooth lock washer or an external tooth style?
Internal tooth, like the JLWI9, keeps all the serrations hidden under the bolt head or nut, so the finished joint looks clean and the teeth do not mar the visible surface. External tooth washers spread the bite over a larger diameter and hold better on soft or oversized-hole material. For panel screws, enclosure covers and device mounting where appearance matters, internal tooth is the usual pick.
3) Are these 1/2 inch lock washers plated for indoor electrical and mechanical work?
They are zinc plated steel. That gives ordinary indoor corrosion protection for electrical, plumbing and HVAC work, which is the application range Metallics lists for them. For wet exterior or corrosive duty, step up to stainless.
4) How many washers come in a jar of Metallics JLWI9?
One jar holds 100 of the 1/2 inch internal tooth lock washers. The jar packaging keeps them from spilling in a van bin or on a service cart, and the filled jar weighs 0.38 lbs.
5) Will a jar of JLWI9 washers fit in a standard parts bin or 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.
6) Do these washers follow ANSI sizing for 1/2 inch hardware?
Metallics lists the JLWI9 to ANSI, so the 1/2 inch internal tooth washer follows the standard dimensional series and interchanges with other ANSI-dimensioned 1/2 inch tooth lock washers on the same bolt.
