Metallics JLW175D – Frequently Asked Questions
1) Can I use the Metallics 1/2 inch split lock washer with 1/2 inch all-thread rod?
Yes. The 0.500 to 0.512 inch inside diameter is sized for 1/2 inch fasteners, so it passes over 1/2-13 all-thread as well as 1/2 inch bolts. Outside diameter is 0.869 inches, so check that your channel nut or bracket seat is wide enough to take it flat.
2) How many washers come in a jar of Metallics JLW175D?
100 washers per jar. The jar is the pack type, which keeps them contained on a truck or a gang box better than a poly bag, and the whole jar weighs 1.32 lbs.
3) Are these 1/2 inch lock washers zinc plated for damp or outdoor electrical work?
They're steel with a zinc chromate finish, which gives corrosion protection for typical indoor and protected outdoor electrical installs like strut hangers, panel mounting and conduit supports. For continuous wet, coastal or corrosive process environments, buyers normally step up to stainless.
4) What is the difference between a split lock washer and a flat washer on an electrical mounting job?
A split lock washer like the JLW175D is a helical spring ring that presses back against the nut to resist vibration loosening. A flat washer does nothing about vibration, it just spreads the clamp load over a wider area and protects the surface. On strut, motor and panel hardware the common practice is both: flat washer against the material, split lock under the nut.
