Metallics JSLW91 – Frequently Asked Questions
1) What bolt size does the Metallics JSLW91 split lock washer fit?
The JSLW91 is a 3/8 inch split lock washer, so it seats under a 3/8 inch bolt head or nut on 3/8-16 or 3/8-24 threaded hardware. The inside diameter is sized to the 3/8 bolt shank, not to the thread pitch, so either pitch works.
2) Are these 3/8 lock washers stainless steel or plated steel?
Stainless steel. That matters if you are mounting outdoors, in damp mechanical rooms, or against stainless strut and hardware, where a zinc plated washer would be the first thing to rust and where mixing metals invites galvanic corrosion. Match the bolt and nut material to the washer for best results.
3) How many 3/8 stainless split lock washers come in a jar of the Metallics JSLW91?
100 washers per jar, packed in a jar rather than a bag or box, which is the format most electricians and MRO stockrooms want on the truck or the shelf because it reseals and stays sorted. Jar weight is 0.68 lbs.
4) Should I use a split lock washer or a flat washer under a 3/8 bolt?
They do different jobs and are often used together. A split lock washer like the JSLW91 puts spring tension on the joint and digs into the nut and the mating surface to resist loosening from vibration. A flat washer spreads the clamp load and protects softer material from being chewed up. On strut, panel mounting, and equipment anchoring where vibration is the concern, the split lock is the one that keeps the nut from backing off; add a flat washer under it if the surface is soft or the hole is oversized.
5) Can these Metallics split lock washers be used outside the electrical trade, like on plumbing or HVAC work?
Yes. Metallics lists the field application as the electrical, plumbing, heating and air conditioning industries. It is a standard 3/8 stainless split lock washer, so anywhere a 3/8 bolted connection needs vibration resistance, it applies, including strut hangers, pipe clamps, and equipment mounts.
