Metallics JSLW9D – Frequently Asked Questions
1) What bolt size do the Metallics JSLW9D split lock washers fit?
The JSLW9D is a 3/8 inch split lock washer, so it goes under the nut or bolt head on 3/8 inch diameter threaded fasteners. Split lock washers are sized by the bolt diameter they ride on, not by outside diameter, so any 3/8-16 or 3/8-24 bolt takes this washer.
2) Are these Metallics 3/8 lock washers stainless steel or plated?
Stainless steel, not zinc-plated carbon. That matters for outdoor strut runs, rooftop equipment supports, wet rooms and coastal work where a plated washer would rust and bleed onto the finish. Pair them with stainless bolts and nuts to avoid mixing metals in the same joint.
3) Should I use a split lock washer or a flat washer on a 3/8 strut connection?
They do different jobs and are often used together. A split lock washer like the JSLW9D is a helical spring that bites into the nut and the mating surface to resist loosening under vibration. A flat washer spreads clamp load and protects a soft or slotted surface. On strut, equipment frames, and motor mounts, the common stack is flat washer against the material, lock washer under the nut. If you only need bearing area and no vibration resistance, a flat washer alone is enough.
4) Will stainless split lock washers work on galvanized strut and hardware?
Mechanically yes, a 3/8 stainless split lock washer seats on galvanized channel nuts and strut the same as a plated one. Be aware you are putting stainless against zinc, and in a wet or exterior location that pairing will sacrifice the zinc coating over time. For dry indoor runs it is a non-issue; outdoors, keep the whole fastener stack stainless.
5) Do these washers follow a standard sizing spec?
The JSLW9D is built to ANSI dimensional sizing for a 3/8 inch split lock washer, so inside diameter, width and thickness match what a drawing calling out a standard 3/8 helical spring washer expects. It will interchange with other ANSI-dimensioned 3/8 lock washers already on the job.
