Carbon Steel DIN 25201 Wedge Locking Washer
Product Overview
DIN 25201 Wedge Locking Washer is a highly reliable locking solution designed to maintain bolted joint integrity even under conditions of extreme vibration and dynamic loads. This self-locking washer system consists of two identical washers with radial teeth on one side and a wedge ramp on the other, which interlock during installation. These washers are engineered to secure fasteners where standard washers may fail, particularly in high-stress mechanical assemblies using carbon steel bolts.
DIN 25201 Wedge Lock Washers are commonly used when safety and reliability are paramount. Their performance far exceeds that of standard lock washers by using tension rather than friction to prevent loosening.

Material Description & Manufacturing Process
Our DIN 25201 Wedge Locking Washer is crafted from premium carbon steel, delivering high tensile strength and longevity under mechanical stress. Carbon steel is selected for its favorable strength-to-cost ratio and its compatibility with a variety of coatings including zinc plating and black oxide for improved corrosion resistance.
Manufacturing Process:
- Raw material inspection & selection
- Precision stamping and forming
- Hardening heat treatment
- Surface coating (by request: Zinc, Electro-galvanized, Delta Protekt®)
- Laser marking (optional for part identification)
- Final dimensional and functional inspections
This process ensures every washer meets tight dimensional tolerances and mechanical strength requirements.
Common Industries and Application Scenarios
DIN 25201 Wedge Lock Washers serve critical roles in industries where vibration and safety are top concerns, including:
- Railway systems and signaling equipment
- Wind turbine installations
- Heavy machinery and construction equipment
- Automotive and commercial vehicles
- Aerospace manufacturing
- Marine and offshore installations
- Renewable energy and solar panel mounting systems
These washers are particularly vital when the cost of joint failure—either financially or in safety terms—is high.
