Metallics JLWHA177 – Frequently Asked Questions
1) What bolt size do the Metallics JLWHA177 split lock washers fit?
They're 3/4 inch split lock washers, so they go under a nut or bolt head on 3/4 inch diameter threaded fasteners. One jar holds 100 pieces.
2) Are these lock washers rated for use with Grade 5 and Grade 8 bolts?
Yes. Metallics lists the JLWHA177 as a G5+G8 split lock washer, meaning it is intended for both Grade 5 and Grade 8 hardware, so you can use the same washer on standard and high-strength bolted connections.
3) What is the finish on these 3/4 split lock washers, and will they hold up outdoors?
Steel with a yellow zinc plating. Yellow zinc gives better corrosion resistance than plain steel for damp or exterior-adjacent work such as strut runs, equipment pads and outdoor disconnect mounting, but it is a plated carbon steel part, not stainless, so it isn't a substitute for stainless in constant wet or coastal exposure.
4) Should I use a split lock washer or a flat washer under a 3/4 inch nut?
Different jobs. A split lock washer like the JLWHA177 bites into the nut and the mating surface to resist loosening from vibration, which is why it goes on motor mounts, strut, transformer and equipment anchoring. A flat washer only spreads load over a larger area and does nothing to stop back-off. On jobs that see vibration, many specs call for a flat washer against the material with the split lock stacked between it and the nut.
5) Do these Metallics lock washers meet ANSI dimensional sizing?
Metallics lists the JLWHA177 to ANSI, so the 3/4 inch split ring follows standard ANSI washer sizing and will seat under standard 3/4 inch hex nuts and bolt heads from any manufacturer. Country of origin is China.
6) How many 3/4 inch split lock washers come in a jar, and how heavy is it?
The JLWHA177 ships as a jar of 100 pieces weighing 3.69 lbs. The jar measures 3.5 x 3.5 x 5.75 inches, so it stores easily on a van shelf or in a job box without repackaging.
