Our DIN 6799 Shaft Lock Washers, commonly referred to as E-clips or E-type circlips, are a highly efficient and economical solution for creating a secure shoulder on small-diameter shafts. Characterized by their distinctive three-pronged, semi-open “E” shape, these fasteners are designed for quick radial installation. This means they can be snapped into a groove from the side of a shaft, making them ideal for automated assembly and for applications where axial access is limited. Once installed, the E-clip provides a surprisingly large retaining surface, effectively preventing the axial movement of components like gears, pulleys, and bearings. They are a fundamental component in countless compact mechanical and electronic assemblies.
The functionality of the DIN 6799 E-clip stems from its spring-action design. It is installed by simply pushing it into a pre-machined groove on a shaft until it audibly “clicks” into place. The clip’s three internal prongs grip the bottom of the groove, while its inherent elasticity ensures a tight, vibration-resistant fit. For this product line, we offer high-quality 65Mn carbon spring steel, which is heat-treated to achieve the necessary hardness and resilience. The black oxide finish provides a good level of corrosion resistance and a sleek, uniform appearance, making it suitable for a wide range of industrial and commercial applications. We also offer these clips in 304 stainless steel for environments requiring higher corrosion protection.
