Metric Sizes DIN 127B Split Lock Washer w/ Plain Finish

Metric Sizes DIN 127B Split Lock Washer with Plain Finish

Metric Sizes DIN 127B Split Lock Washers with a plain finish are widely used fastening components designed to help prevent loosening caused by vibration, torque, or dynamic loads. These washers are a critical part of many industrial assemblies where maintaining bolt tension is essential for safety, durability, and long-term performance. Commonly used with metric bolts and nuts, DIN 127B washers are engineered to provide dependable locking action across a wide range of mechanical and structural applications.

Manufactured according to the DIN 127B standard, these split lock washers feature a helical split design that creates spring tension when compressed under a fastener. As the bolt or nut is tightened, the washer flattens slightly, generating continuous pressure that helps resist rotational loosening.

Key Features of DIN 127B Split Lock Washers

Helical Split Locking Design

The defining feature of the DIN 127B washer is its split, helical shape. This design creates spring-like tension between the fastener and the clamped surface, increasing friction and helping prevent loosening caused by vibration or movement.

Plain Finish for Versatile Applications

A plain finish means the washer is supplied without additional coatings or plating. This makes it ideal for controlled environments where corrosion protection is not required or where plating could interfere with electrical conductivity or finishing processes.

Precision Metric Sizing

DIN 127B split lock washers are available in a full range of metric sizes, commonly including M3, M4, M5, M6, M8, M10, M12, M16, and larger diameters. Each washer is designed to properly match the corresponding metric bolt size, ensuring consistent load distribution and locking performance.

Common Industrial Applications

Metric DIN 127B split lock washers are used across many industries that require secure, vibration-resistant fastening. Typical applications include:

• Industrial machinery and equipment assembly

• Automotive and transportation systems

• Construction and structural fastening

• Electrical panels and mechanical housings

• Agricultural and heavy equipment

Reliable Fastener Support for Secure Assemblies

When used alongside metric bolts and nuts, DIN 127B split lock washers with plain finish provide a simple yet effective method of maintaining joint integrity. Their spring tension design improves resistance to loosening while distributing load across the fastened surface.

For manufacturers, maintenance teams, and mechanical engineers, these washers remain a trusted, cost-effective solution for reliable vibration resistance in metric fastening systems.
