Metallics JLWHA178 – Frequently Asked Questions
1) What bolt size do the Metallics JLWHA178 split lock washers fit?
They're 7/16 inch split lock washers, so they go under a nut or bolt head on 7/16-14 or 7/16-20 threaded fasteners. Sold as model JLWHA178 in a jar of 100.
2) Are these lock washers rated for grade 5 and grade 8 bolts?
Yes. The JLWHA178 is a G5+G8 split lock washer, so it's suited to both SAE grade 5 and grade 8 hardware rather than being limited to low-grade fasteners.
3) Will yellow zinc split lock washers hold up outdoors or in a damp mechanical room?
The material is steel with a yellow zinc finish, which gives moderate corrosion resistance for indoor, covered, and damp interior work. For permanently wet or coastal exposure, stainless or hot dip galvanized hardware is the better call.
4) Split lock washer or flat washer for strut and conduit hanger assemblies?
Two different jobs. A split lock washer like the JLWHA178 is a spring washer that bites the nut face and resists loosening from vibration; a flat washer only spreads load over a soft or oversized hole. On vibrating equipment mounts, many installers use both, flat washer against the surface and the split lock under the nut.
5) Do these Metallics washers meet ANSI dimensional sizing?
The JLWHA178 is listed to ANSI, so the inside diameter, width, and thickness follow the standard 7/16 helical spring lock washer dimensions and it will interchange with other ANSI-dimensioned 7/16 split locks already on the job.
6) Where is the Metallics JLWHA178 lock washer made?
Country of origin is China. Worth knowing up front if you're bidding public or federal work with domestic sourcing requirements on fasteners.
