Metallics JLWHA174 – Frequently Asked Questions
1) What bolt size do the Metallics JLWHA174 split lock washers fit?
They're 3/8 inch split lock washers, sized to go under a 3/8-16 or 3/8-24 nut or bolt head. The split ring bites into the nut face and the joint surface to resist loosening under vibration.
2) Are these lock washers rated for use with Grade 5 and Grade 8 bolts?
Yes. The JLWHA174 washers are specified for Grade 5 and Grade 8 fasteners, so they hold up under the higher clamp loads of hardened structural bolting rather than just low-grade general assembly.
3) Will yellow zinc split lock washers hold up outdoors or in damp electrical rooms?
The material is steel with a yellow zinc plating, which gives decent corrosion resistance for indoor, damp-location and sheltered exterior work. For direct weather exposure, submerged conditions or coastal air, step up to a stainless or hot-dip galvanized lock washer instead, because zinc plating is a thin sacrificial coating.
4) How many 3/8 split lock washers come in a jar?
100 pieces per jar. The pack is a jar rather than a bag or box, which is the format most electricians keep on the van or in a bench rack because it reseals and the count stays intact. The jar weighs 0.67 lbs.
5) Should I use a split lock washer or a flat washer under my strut and channel hardware?
They do different jobs. A split lock washer like the JLWHA174 resists the nut backing off under vibration, which is what you want on motor mounts, transformer frames, panel and rack bolting, and threaded rod hangers. A flat washer spreads load over soft or oversized holes. On soft material or slotted strut you often want both: flat washer against the material, split lock washer under the nut.
6) Can I use these on a stainless steel bolt or stainless strut?
Not a good pairing. These are zinc plated steel, and putting plated carbon steel against stainless in a wet location sets up galvanic corrosion that eats the plating and then the washer. Match a stainless split lock washer to stainless bolting. For dry interior work with stainless hardware the mismatch is far less of an issue.
7) What is the jar size for the Metallics JLWHA174, and will it fit a parts bin?
The jar measures 3 x 3 x 2.15 inches, so it drops into most standard van bin slots and bench drawer organizers without decanting.
