Spring Lock Washer

Product Description：

A spring lock washer is a mechanical component designed to prevent the loosening of fasteners due to vibrations or dynamic loads. Its helical shape allows it to exert a continuous force against the fastener, maintaining tension and ensuring a secure connection. Commonly used in automotive, aerospace, and industrial applications, spring lock washers are essential for maintaining the integrity of bolted joints. They are typically made from high-carbon steel to provide durability and resistance to corrosion. Available in various sizes and grades, spring lock washers are compatible with a wide range of bolts and nuts, offering versatility in fastening solutions. Their design and material properties make them a reliable choice for preventing fastener loosening in critical applications.

Frequently Asked Questions:

Q1: What is a spring lock washer?

A: It’s a helical-shaped washer that applies continuous tension when installed, preventing nuts or bolts from loosening.

Q2: How do I install it correctly?

A: Place the washer between the bolt (or screw) and the nut, then tighten with a standard wrench—no special tools or preparation needed.

Q3: Can it be disassembled and reassembled repeatedly?

A: Yes. Even after multiple removals, the washer will recover its elasticity and maintain its locking effect.
