Product Details
The ingenious design of the DIN 6799 E-clip lies in its simplicity and function. It is installed by simply pushing it radially into a machined groove on a shaft until it “snaps” securely into place. The three internal prongs of the “E” make firm contact with the bottom of the groove, while the overall spring tension of the clip holds it firmly in position. This creates a reliable retaining shoulder that can withstand moderate axial loads.
We manufacture these essential components from high-quality carbon spring steel, which is heat-treated for optimal elasticity and hardness, or from durable stainless steel for applications requiring superior corrosion resistance. A variety of finishes, including polished, black oxide, and zinc-plated, are available to meet specific environmental and performance requirements.

Product Features
Our DIN 6799 E-clips are engineered for efficiency and reliability, offering several distinct advantages:
- Convenient Radial Installation: Can be quickly installed from the side of the shaft, eliminating the need for axial clearance and simplifying assembly processes.
- Large Retaining Shoulder: Despite its compact form, the E-clip provides a surprisingly large and effective shoulder for retaining components against axial forces.
- Space-Saving Design: Its low profile and minimal radial protrusion make it the perfect choice for compact designs where space is at a premium.
- Secure Grip: The inherent spring action of the clip ensures it remains tightly seated in the groove, providing excellent resistance to vibration and shock.
- Economical Fastening Solution: As a simple, stamped component, the E-clip is a highly cost-effective method for achieving reliable axial retention on small shafts.
Product Applications
DIN 6799 E-clips are ideal for light to medium-duty applications where a compact and easily assembled retaining solution is needed. They are widely used across numerous industries:
- Electronics and Office Equipment: Securing small gears, knobs, and rollers on shafts within printers, copiers, and other electronic devices.
- Automotive Systems: Used in small linkages, sensor assemblies, and interior mechanisms.
- Toys and Hobby Models: A common component for assembling wheels, propellers, and moving parts.
- Small Mechanical Assemblies: Perfect for retaining pins, pivots, and other small components in a wide variety of machinery and tools.
