Metallics JSLW11 – Frequently Asked Questions
1) What bolt size do the Metallics JSLW11 split lock washers fit?
The JSLW11 is a 7/16 inch split lock washer, so it seats on 7/16 inch bolts, screws and threaded rod. The inside diameter is sized to that same 7/16 nominal bolt diameter, so it slips over the shank and bears against the nut or bolt head.
2) Are these Metallics 7/16 washers stainless steel or plated steel?
Stainless steel. The JSLW11 is a stainless split lock washer, which is what you want when the fastener itself is stainless or when the assembly sees moisture, washdown or outdoor exposure and a zinc plated washer would be the first thing to rust.
3) What does a split lock washer actually do, and should I use one instead of a flat washer?
A split lock washer is a single coil with a gap, and it is a locking element, not a load spreader. Compressed under the nut, the split ends bite into the nut face and the joint surface to resist loosening from vibration. A flat washer only distributes bearing load and adds no resistance to backing off. On equipment or conduit supports that vibrate, the usual practice is a flat washer against the material for bearing plus the 7/16 split lock under the nut. If all you need is to protect a soft surface, a flat washer is the right part instead.
4) Can I use stainless split lock washers on electrical strut and conduit hangers outdoors?
That is the intended use. Metallics lists the JSLW11 for the electrical, plumbing, heating and air conditioning trades, and the stainless material holds up where plated hardware corrodes, such as rooftop and exterior strut runs or mechanical rooms. Pair it with stainless bolts and nuts of the same 7/16 size so you are not mixing metals in the joint.
5) Are the Metallics JSLW11 split lock washers made to a dimensional standard?
They are built to ANSI dimensions for 7/16 split lock washers, so the inside diameter, width and thickness match what a spec calling out an ANSI helical spring lock washer expects. Country of origin is listed as multiple.
