Metric Zinc Plated Steel Split Ring Lock Washers

How do I size metric zinc split ring lock washers?

Metric zinc plated split ring washers combine metric sizing with an economical zinc finish for light-duty vibration resistance in dry and mild conditions. As the fastener is torqued, the sharp ends bite the surface and the spring holds tension against loosening. Match the washer to your metric bolt size, such as M4, M6, M8, or M10. For wet, coastal, or chloride exposure where the zinc would eventually corrode, step up to metric A2 or A4 stainless. Tighten to the correct torque and avoid over-tightening.

Why choose metric zinc plated steel split ring lock washers

• Metric sizing: matched to M-series bolt diameters.
• Economical: cost-effective zinc finish for common jobs.
• Vibration locking: split ring bites the surface to resist loosening.
• Corrosion resistant: zinc plating protects better than bare steel.

Common applications for metric zinc split ring lock washers

• Metric machinery and equipment
• Imported and automotive hardware
• Indoor and dry outdoor metric assembly
• Light-duty metric vibration joints

Metric Zinc Plated Steel Split Ring Lock Washers FAQ

What metric sizes are available?

Common metric diameters such as M4, M6, M8, and M10. Match the washer to your metric bolt size.

Are metric zinc split ring washers good outdoors?

The zinc plating suits indoor and general dry outdoor use. For wet, coastal, or saltwater exposure, choose metric A2 or A4 stainless.

How does the split ring lock the joint?

Its sharp cut ends bite into the surfaces while the helical spring maintains tension, resisting rotation and loosening in light-duty vibration.
