Metallics JSLW781 – Frequently Asked Questions
1) What bolt size does the Metallics JSLW781 split lock washer fit?
The JSLW781 is a 7/8 inch split lock washer, so it goes over 7/8 inch diameter bolts, studs, or threaded rod. Split lock washers are sized by the nominal bolt diameter they ride on, not by outside diameter, so a 7/8 washer pairs with a 7/8-9 or 7/8-14 fastener.
2) Are these lock washers stainless steel or plated steel?
Stainless steel. That matters if the hardware is going outdoors, in a wet well, on rooftop strut, or anywhere a zinc-plated washer would bleed rust. Pair it with stainless bolts and nuts to avoid mixing metals at the joint.
3) How many 7/8 split lock washers come in a jar?
100 pieces per jar. The JSLW781 ships as a single jar, not loose count, so the order minimum for an MRO crib or a job trailer is the full 100.
4) Can I use these stainless split lock washers on outdoor electrical equipment?
Yes, that is the usual application. Stainless construction handles exterior and damp-location service without rusting, and the 7/8 size fits the larger anchor bolts and threaded rod found on pad-mounted gear, generator bases, and heavy support steel.
5) Should I use a split lock washer or a flat washer on a 7/8 bolted connection?
Different jobs. A split lock washer like the JSLW781 bites into the nut face and the mating surface to resist loosening from vibration; a flat washer spreads load and protects the surface but does nothing against vibration. On equipment pads, transformer mounts, motor bases, and strut connections that see cycling, crews commonly run both: flat washer against the material, split lock under the nut.
6) Are these 7/8 stainless lock washers made to a dimensional standard?
The JSLW781 is built to ANSI dimensions for a 7/8 split lock washer, so the thickness and outside diameter match standard ANSI prep and it will seat under a standard 7/8 hex nut without overhanging the bearing surface.
7) Where are Metallics JSLW781 washers manufactured?
Country of origin is China. If you are bidding a project with domestic sourcing requirements, that is the detail to check against your spec before you commit the fastener package.
