Metallics JLW153 – Frequently Asked Questions
1) Are split lock washers the right choice for keeping panel and device screws from backing out from vibration?
That is exactly what a split lock washer does. The split ring spreads under the nut or screw head and pushes back as it is tightened, keeping tension on the threads so the fastener resists loosening under vibration. A flat washer spreads load across soft material but does nothing to stop backout, so many installers stack both, flat against the surface and the split lock under the head. The JLW153 is the #12 split lock version in steel.
2) Will zinc chromate plated steel washers hold up in a damp mechanical room or outdoor enclosure?
The JLW153 is plated steel with a zinc chromate finish, which gives ordinary indoor and protected-outdoor corrosion resistance, typical for panel work, conduit strut, and equipment mounting. For continuous wet, coastal, or corrosive process areas, spec a stainless split lock instead, plating will eventually give up in those conditions.
3) What part number do I order for Metallics #12 zinc plated split lock washers?
Order Metallics JLW153. That single part number covers the #12 split lock washer in zinc chromate plated steel, packed 100 to a jar, with no finish or pack options to specify.
4) How many washers come in a jar of Metallics JLW153?
They ship 100 to a jar. The jar pack is what makes these practical on a service truck, you scoop what you need instead of chasing loose washers around a tray. The jar of 100 weighs 0.17 lbs.
5) Are these #12 split lock washers only for electrical work?
No. Metallics lists the JLW153 for electrical, plumbing, heating and air conditioning work, so the same jar covers panel and device screws, strut and hanger hardware, and equipment mounting across those trades. It is general fastener hardware, not an electrical-only item.
6) How much shelf or bin space does a jar of Metallics JLW153 washers take up?
The jar measures 3 x 3 x 2.15 inches, so it drops into a standard small parts bin or a van shelf slot without taking a full drawer. Handy if you are standardizing a truck stock on jarred fasteners.
