Metric Sizes A4 Stainless Steel Split Lock Washer

Metric Sizes A4 Stainless Steel Split Lock Washer

Metric Sizes A4 Stainless Steel Split Lock Washers are critical fastening components designed to help prevent bolts and nuts from loosening due to vibration, thermal expansion, or mechanical movement. These washers are widely used in demanding environments where corrosion resistance and secure fastening are essential. Manufactured from A4 stainless steel (commonly known as 316 stainless steel), these split lock washers provide superior durability and long-term performance in harsh industrial and marine conditions.

The split helical design of a lock washer creates spring tension when compressed beneath a nut or bolt head. This tension increases friction between the mating surfaces, helping maintain proper clamp load and preventing the fastener from backing out during operation.

Key Features of A4 Stainless Steel Split Lock Washers

Helical Split Locking Design

The defining feature of a split lock washer is its helical cut, which allows the washer to act as a spring when tightened. As torque is applied to the fastener, the washer compresses and exerts outward pressure against the fastener and surface material. This helps resist loosening caused by vibration or repetitive motion in machinery and structural assemblies.

A4 (316) Stainless Steel Construction

A4 stainless steel, also known as 316 stainless steel, contains molybdenum, which greatly improves corrosion resistance. This material is highly resistant to saltwater, chemicals, and moisture, making A4 stainless lock washers ideal for marine, food processing, pharmaceutical, and chemical industry applications.

Precision Metric Sizing

A4 stainless steel split lock washers are available in a wide range of metric sizes, typically including M3, M4, M5, M6, M8, M10, M12, M16, and larger. Each washer is designed to match the corresponding bolt or screw diameter, ensuring proper fitment and optimal locking performance.

Common Industrial and Marine Applications

Metric A4 stainless steel split lock washers are commonly used in applications requiring both vibration resistance and corrosion protection, including:

• Marine and offshore equipment

• Chemical processing systems

• Food and beverage processing machinery

• Outdoor construction and infrastructure

• Industrial equipment exposed to moisture or corrosive environments

Reliable Fastener Security in Harsh Environments

When paired with stainless steel bolts and nuts, A4 Stainless Steel Split Lock Washers provide a dependable solution for maintaining tight, vibration-resistant assemblies. Their combination of spring tension design and superior corrosion resistance makes them a trusted choice for long-lasting performance in demanding environments.
