[50000 BULK] Medium Split Lock Washers Steel Plain 4

Secure every project with our Medium Split Lock Washers in steel with a plain finish. Sized at 4, these locking washers deliver reliable anti-loosening performance in a wide range of fastening applications.

Why choose these washers

• Secure locking: The split design creates a spring force that resists loosening under vibration and dynamic loads.
• Durable steel: Made from sturdy steel for long service life in general hardware assemblies.
• Plain finish: Uncoated steel suitable for coating processes or general-purpose use.
• Size 4: Precisely sized for compatibility with corresponding bolts and nuts.
• Versatile: Ideal for automotive, machinery, electrical, and equipment assemblies.

How to use

Place the washer between the bolt head or nut and the surface. Tighten to the recommended torque to engage the locking action. Ensure the washer is properly oriented and sits flat for maximum effect. Use with compatible bolt sizes and materials to avoid galvanic corrosion or excessive wear.

Care and compatibility

Plain steel washers are not inherently corrosion-resistant. In humid or corrosive environments, consider plated or coated variants or apply appropriate protective finishes. Check compatibility with your fastener materials to minimize wear.
