Metallics JLWHA173 – Frequently Asked Questions
1) What bolt size do the Metallics JLWHA173 split lock washers fit?
They're 5/16 inch split lock washers, so they go on 5/16 inch bolts and screws. Each jar holds 100 pieces.
2) Are these 5/16 lock washers rated for grade 5 and grade 8 bolts?
Yes. The JLWHA173 split lock washers are called out for use with Grade 5 and Grade 8 fasteners, so they're suitable for higher-strength bolted connections rather than low-grade hardware only.
3) What finish are the Metallics JLWHA173 washers, and will they hold up outdoors or in damp areas?
Steel with a yellow zinc plating. Yellow zinc gives better corrosion resistance than plain steel for damp interior work, strut runs, and sheltered exterior locations, but it isn't stainless, so continuous wet or coastal exposure calls for a stainless washer instead.
4) Should I use a split lock washer or a flat washer on my 5/16 electrical mounting hardware?
Different jobs. A split lock washer like the JLWHA173 bites into the nut and the surface to resist loosening from vibration, which is what you want on motor mounts, transformer frames, strut, and panel hardware. A flat washer spreads load and protects the surface but does nothing against vibration. On soft or oversized material many installers run both: flat against the material, split lock under the nut.
5) What part number do I order for Metallics 5/16 yellow zinc split lock washers?
Order Metallics JLWHA173. That's the single model covering the 5/16 split lock washer in steel yellow zinc, 100 per jar.
6) How are the Metallics 5/16 split lock washers packaged for a service van or shop bin?
They ship in a jar of 100, which keeps them contained on a shelf or in a van bin rather than loose in a bag. The jar weighs 0.46 lbs and measures 3 x 2.15 x 3 inches, so it drops into a standard small-parts organizer.
7) Where are the Metallics JLWHA173 lock washers made?
Country of origin is China. Worth knowing up front if you're bidding a job with domestic-sourcing requirements, since that would rule these out.
