Metallics JSLW7D – Frequently Asked Questions
1) What bolt size do the Metallics JSLW7D split lock washers fit?
The JSLW7D is a 1/4 inch split lock washer, so it goes on 1/4-20 or 1/4-28 bolts and screws. If your hardware is 5/16 or 3/8, this is the wrong size and you need the matching diameter washer instead.
2) Are these 1/4 inch lock washers stainless steel or plated steel?
Stainless steel, not zinc-plated carbon steel. That matters for outdoor enclosures, rooftop unit mounting, wet locations, and coastal jobs where a plated washer rusts and seizes on the bolt. For dry indoor strut and panel work, plated steel is usually accepted.
3) What does a split lock washer actually do, and do I still need a flat washer with it?
A split lock washer is a single coiled turn that spreads open under torque; it keeps spring tension on the joint and its sharp cut ends bite the nut and the surface to resist loosening from vibration. It does not spread load, so on sheet metal, strut, or soft material you still want a flat washer underneath it. The JSLW7D covers the locking function only.
4) Are these Metallics stainless lock washers made in the USA for a Buy American job?
Country of origin is the United States, and the washers are built to ANSI dimensional convention. That is what a government, school district, or federally funded project submittal usually wants to see on a fastener line item.
5) Can I use a stainless split lock washer with a stainless bolt without galling?
Matching stainless to stainless is the right call for corrosion, and the JSLW7D is stainless steel. Be aware that stainless on stainless can gall if you run the nut down fast and dry; back off the speed or use an anti-seize on larger assemblies. Mixing a stainless washer against plated carbon steel hardware in a wet location sets up galvanic corrosion on the plated part.
6) How much does a jar of 100 Metallics 1/4 inch stainless lock washers weigh and how big is the jar?
The jar weighs 0.31 lbs and measures 3 x 3 x 2.15 inches, so it drops into a standard van bin or tool bag compartment without repacking.
