Metallics JSLW91D – Frequently Asked Questions
1) What bolt size do Metallics JSLW91D split lock washers fit?
The JSLW91D is a 3/8 inch split lock washer, so it goes under a nut or bolt head on 3/8-16 or 3/8-24 hardware. The inside diameter is sized to the 3/8 inch shank, not to the thread pitch, so either pitch works.
2) Are these lock washers stainless steel, and can they be used outdoors or in damp locations?
Stainless steel, which is why electricians reach for them on exterior strut runs, rooftop equipment, wet-location enclosures and anywhere plated steel would rust and seize. Pair them with stainless bolts and nuts to avoid mixing metals in the joint.
3) How many 3/8 split lock washers come in a jar?
100 pieces per jar, packed in a screw-top jar rather than a bag, which holds up better in a van drawer or on a shelf than a split poly bag. Jar weight is 0.67 lbs.
4) Should I use a split lock washer or a flat washer with my 3/8 bolt?
They do two different jobs. A split lock washer like the JSLW91D is a helical spring ring that bites into the nut and the surface to resist loosening from vibration. A flat washer spreads the clamp load over a wider area and protects the surface. On equipment that vibrates, such as motors, panels and strut-mounted gear, many installers use both: flat washer against the material, split lock washer under the nut.
5) Are these 3/8 lock washers made in the USA?
Country of origin is the United States, which matters on public works and federally funded jobs with domestic-sourcing requirements. The washers are also built to ANSI dimensional practice.
6) Will stainless 3/8 split lock washers work with galvanized strut and hardware?
They will thread on and function, but stainless against hot-dip galvanized puts two dissimmilar metals in contact, and in wet or coastal conditions that invites galvanic corrosion at the joint. For a galvanized strut run indoors it is commonly done without issue; outdoors, keep the whole stack one material family. The JSLW91D is stainless steel.
7) What part number do I order for Metallics 3/8 stainless split lock washers?
Order MPN JSLW91D from Metallics. That number covers the 3/8 inch stainless split lock washer in the 100-count jar.
