Metallics JG8LW172 – Frequently Asked Questions
1) What bolt size does the Metallics JG8LW172 split lock washer fit?
The JG8LW172 is a 1/4 inch split lock washer, so it goes under the nut or bolt head on 1/4-20 or 1/4-28 hardware. It is a Grade 8 washer in zinc plated steel, intended to pair with higher strength 1/4 inch bolting rather than general purpose hardware.
2) How many 1/4 inch Grade 8 split lock washers come in a jar of the Metallics JG8LW172?
One hundred washers per jar, packed in a jar rather than a box or bag. The jar is handy on a cart or in a gang box because it reseals; total packed weight is about 0.3 lbs.
3) Will a zinc plated steel split lock washer hold up outdoors or in a damp mechanical room?
Zinc plated steel gives moderate corrosion resistance, which is fine for indoor electrical work, panel and strut assembly, and covered exterior locations. It is not stainless, so for direct weather exposure, wet process areas, or coastal sites, specify a stainless split lock washer instead of this one.
4) What does a split lock washer actually do, and do I still need a flat washer with it?
A split lock washer bites into the nut face and the joint surface as it compresses, resisting loosening from vibration. It does not spread load, so on soft material, sheet metal, or an oversized hole you still want a flat washer under the split washer. On a drilled steel channel or strut the split washer alone is normally what gets specified.
5) Is the Grade 8 rating on this 1/4 inch lock washer the same as a Grade 8 bolt?
Grade 8 here designates the washer's own hardened strength class so it does not crush or flatten under the clamp load of high strength fastening. Match it with Grade 8 bolting on 1/4 inch connections; a soft general purpose lock washer under a Grade 8 bolt will flatten and lose its spring.
6) Is this Metallics washer dimensionally standard so it interchanges with washers I already stock?
Yes. The JG8LW172 is built to ANSI dimensional standards for 1/4 inch split lock washers, so inside and outside diameters match other ANSI 1/4 inch split lock washers in your bins. Country of origin is China.
7) What are the carton dimensions on the jar of 100 Metallics split lock washers for shelf or van storage?
The packed jar measures 3 x 3 x 2.15 inches and weighs 0.3 lbs, so it fits a standard parts bin or a drawer in a van shelving unit without repacking.
