Metallics JLW172M – Frequently Asked Questions
1) What size bolt does the Metallics JLW172M split lock washer fit?
The JLW172M is a 1/4 inch split lock washer, so it goes under the nut or bolt head on 1/4-20 and 1/4-28 hardware. It is a helical split ring, not a flat washer, so it does not spread load across a surface; it keeps tension on the joint against loosening.
2) How many 1/4 inch lock washers come in a jar of Metallics JLW172M?
One thousand washers per jar. They ship in a jar pack rather than a bag or box, which is what most electricians and MRO stockrooms want on a bench or cart since the jar reseals and the washers do not spill. Jar weight is listed at 2.35 lbs.
3) Are Metallics JLW172M lock washers zinc plated steel, and will they hold up outdoors?
These are steel washers with a zinc plating. Zinc plating is a mild corrosion barrier meant for dry indoor and protected work, panel interiors, strut runs inside a building, equipment enclosures. For wet exterior, coastal, or wash-down locations, step up to hot-dip galvanized or stainless split lock washers instead.
4) Split lock washer or a nylon insert lock nut for 1/4 inch electrical hardware?
A split lock washer like the JLW172M works under a standard hex nut and is reusable in the sense that it is cheap to replace on every rework, and it has no temperature limit from a plastic insert. A nylon insert lock nut is better where vibration is constant and you want one piece instead of two, but the insert degrades with heat and repeated removal. For general 1/4 inch strut, enclosure, and bonding hardware in a building, the split washer is the usual call.
5) Can I use a 1/4 inch split lock washer with a flat washer on the same bolt?
Yes, and that is the normal stack-up: flat washer against the material, split lock washer between the flat washer and the nut. The flat washer spreads the load so the sharp ends of the split ring do not dig into sheet metal or soft material. The JLW172M only covers the lock washer half of that stack, so order 1/4 inch flat washers separately if the job needs both.
6) Are the Metallics JLW172M washers made to ANSI dimensions?
Yes, the JLW172M carries an ANSI dimensional designation, so the 1/4 inch split ring matches standard ANSI sizing and will seat correctly under off-the-shelf 1/4 inch hex nuts and bolt heads from any supplier.
7) What are the jar dimensions on the Metallics 1/4 inch lock washer jar for shelf storage?
The jar measures 4.57 x 3 x 3 inches and weighs 2.35 lbs filled. That footprint drops into most parts-bin shelving and van racking without repacking.
