Product Description
RS PRO 289-657 Copper Crinkle Locking & Anti-Vibration Washer is engineered for secure fastening and vibration resistance in industrial, electronic, and construction applications. This washer is manufactured from high-quality copper, offering excellent corrosion resistance, especially in environments exposed to seawater and chemical agents like sulphuric acid. The crinkle design delivers a dual purpose: locking action to prevent fastener loosening and vibration absorption to maintain assembly integrity over time.
The washer is intended for use with M3 screws and bolts, ensuring broad compatibility across a range of fastening tasks. With an external diameter of 6.29 mm and an internal diameter of 3.26 mm, its fit is both precise and reliable. The 0.16 mm thickness allows for installation in space-limited environments without sacrificing performance. Its compliance with BS 4463 guarantees its performance and matching industry standards.
In practice, this washer distributes the load of the bolt or screw against the material surface and acts as a lock to prevent rotation and loosening, making it especially valuable wherever vibration or repeated stress is a factor. Such locking washers outperform plain washers when the aim is to prevent fastener movement and surface wear.
Common application areas include electronics, food processing machinery, chemical assembly lines, and construction plumbing. The washer is frequently used for pre-loading and spacing, contributing to the overall stability and durability of the assembly.
This RS PRO washer is a trusted choice for engineers seeking reliability and value, rigorously tested to high standards. Explore more RS PRO fastener solutions in the Washers category to meet a broad range of fastening needs.
