Our Rectangular Section Spring Washers DIN 127B, also known as Split Washers or Spring Lock Washers, are designed to prevent loosening of fasteners by maintaining tension within the assembly. These washers are ideal for use with bolts, nuts, and machine screws in applications subject to vibration, dynamic loads, or thermal expansion.

This product has a rectangular cross-section and straight cut ends, as per the DIN 127B specification, offering a firm and uniform spring action when compressed. They offer excellent corrosion resistance and mechanical strength, making them suitable for use in demanding industrial, marine, and outdoor environments.

What are Rectangular Section Spring Washers?

Rectangular Section Spring Washers DIN 127B are a type of locking washer that exerts continuous axial force to secure a fastener assembly. They feature a split in the ring that creates tension when installed, acting like a spring to resist loosening due to vibration or thermal movement. The DIN 127B form is distinguished by its straight (square) cut ends, unlike the bent ends of DIN 127A. These washers are a reliable solution in applications requiring a tight, lasting fit without frequent retightening.
