Metric Shaft Lock Washers


DIN 5046 shaft lock washers are specialized metric washers designed to prevent nuts from loosening due to vibration. Rather than relying solely on friction, they use tabbed “teeth” to grip onto shaft nuts and ensure a secure connection. Commonly used in machinery and industrial operations, shaft lock washers are critical for joint security and reliability.

Metric & Multistandard supplies shaft lock washers and other metric fasteners for industrial applications. Our comprehensive product catalog contains over 48,000 metric components to ensure we can supply you with the right parts for any job. Shop for shaft lock washers below.

What Are Shaft Lock Washers?

Shaft lock washers are a type of washer that relies on a locking mechanism to prevent rotation. Used with shaft nuts, they feature an internal tab that fits into a groove on the shaft and external teeth that, when tightened, bend around the nut for security. The washer physically prevents loosening, even against high vibrations and shock loads, making them excellent fasteners for demanding industrial and mechanical applications.

Benefits of Shaft Lock Washers

There are many advantages of using shaft lock washers for critical assemblies:
  • Positive locking ensures secure connections
  • Prevents loosening under vibration or impact
  • More reliable than standard friction-only methods
  • Maintains preload and joint security
  • Reusable in many applications with proper use
