Metric Sizes DIN 127B A2 Stainless Steel Split Lock Washer

Metric Sizes DIN 127B A2 Stainless Steel Split Lock Washer

Metric Sizes DIN 127B A2 Stainless Steel Split Lock Washers are widely used fastening components designed to prevent nuts and bolts from loosening due to vibration, dynamic loads, or repeated movement. Built to the DIN 127B standard, these washers feature a split helical design that creates spring tension when compressed under a fastener, helping maintain consistent clamping force in demanding mechanical assemblies.

Manufactured from A2 stainless steel, these split lock washers offer excellent corrosion resistance, strength, and durability. They are commonly used in environments where moisture, humidity, or mild chemicals may be present. Their stainless construction also provides long-term reliability without the need for protective coatings or plating.

Key Features of DIN 127B A2 Stainless Steel Split Lock Washers

Helical Split Locking Design

The split-ring design of the DIN 127B washer forms a slight helical shape. When tightened beneath a bolt head or nut, the washer compresses and creates spring tension that increases friction between the mating surfaces. This tension helps resist loosening caused by vibration, shock, or thermal expansion.

A2 Stainless Steel Construction

A2 stainless steel, often referred to as 18-8 stainless steel, provides excellent resistance to corrosion and oxidation. This makes DIN 127B A2 split lock washers ideal for applications exposed to humidity, water, or outdoor conditions where carbon steel washers may rust.

Precision Metric Sizing

These lock washers are produced in a wide range of metric sizes, including common diameters such as M3, M4, M5, M6, M8, M10, M12, M16, and larger. Each washer is designed to match the corresponding metric bolt or screw size, ensuring proper load distribution and effective locking performance.

Typical Industrial and Commercial Applications

DIN 127B A2 stainless steel split lock washers are commonly used across many industries where corrosion resistance and vibration resistance are required:

• Marine and coastal equipment

• Food processing and sanitary equipment

• Automotive and transportation systems

• Industrial machinery and manufacturing equipment

• Outdoor construction and architectural assemblies

Reliable Locking Performance for Metric Fasteners

When paired with metric bolts and nuts, DIN 127B A2 Stainless Steel Split Lock Washers provide a dependable solution for maintaining tight, secure fastener assemblies. Their corrosion-resistant stainless steel construction and spring locking design make them an excellent choice for long-lasting performance in both indoor and outdoor applications.
