Metallics JLWHA172 – Frequently Asked Questions
1) What bolt size does the Metallics JLWHA172 split lock washer fit?
It's a 1/4 inch split lock washer, so it seats under a 1/4-20 or 1/4-28 nut or bolt head. If you're fastening 5/16 or 3/8 hardware, you need the matching size in that diameter instead, not this one.
2) Can I use these 1/4 split lock washers with Grade 8 bolts, or only Grade 5?
The JLWHA172 washers are rated for both Grade 5 and Grade 8 fasteners, which is what the G5+G8 marking on the jar means. That matters because a washer sized only for a lower grade can flatten out or dish under a hardened Grade 8 bolt at full torque.
3) Are these lock washers plated for outdoor or damp-location use?
They're steel with a yellow zinc finish, which gives corrosion resistance for general indoor and protected service. Yellow zinc is a sacrificial coating, so for direct weather exposure, wet process areas, or coastal work most spec writers call out hot-dip galvanized or stainless instead.
4) Split lock washer or flat washer, which one do I need for a 1/4 inch bolt?
Two different jobs. The JLWHA172 is a split (helical spring) lock washer, so it resists the nut backing off under vibration by biting into the nut face and the joint. A flat washer only spreads load over a wider area and does nothing about loosening. On strut, panel enclosures, and equipment mounts that see vibration, crews often run both: flat washer against the material, split lock under the nut.
