Spring Steel Spring Lock Washers DIN 127B
Spring Lock Washers
Spring lock washers are essential components in mechanical assemblies where vibration and thermal expansion may lead to the loosening of nuts and bolts. These washers are designed with a helical shape that exerts a spring force between the fastener’s head and the substrate, effectively maintaining tension and preventing the fastener from coming undone. Spring lock washers conforming to DIN 127B are a reliable and robust choice for many industrial and commercial applications.
At Flybear Fastener, we manufacture high-quality DIN 127B spring lock washers that deliver consistent performance and reliability in demanding environments.
Product Overview
Spring lock washers are split-type washers that are twisted into a helical shape, which provides axial flexibility. This design enables the washer to apply continuous tension on bolted joints, minimizing loosening over time. Typically used in dynamic load situations, spring lock washers are well-known for their energy-absorbing capacity and anti-vibration properties.
DIN 127B standard defines the geometry, tolerance, and material quality for spring lock washers, ensuring interchangeability and standardization across global industries.

Materials and Manufacturing Process
Our DIN 127B spring lock washers are made using high-grade spring steel such as C60 or C67. These materials are selected for their excellent elasticity and fatigue resistance, essential for preserving the washer’s spring tension over repeated load cycles.
The manufacturing process includes:
- Wire Drawing & Slitting
- Precision Stamping
- Helical Twisting
- Heat Treatment
- Surface Coating (Zinc, Phosphating, Blackening)
- Final Inspection and Sorting
This controlled process ensures that Flybear Fastener washers exceed performance benchmarks in all environments.
Typical Industries and Application Scenarios
Spring lock washers are widely used across industry sectors due to their reliability and resistance to loosening:
- Automotive assemblies (brake systems, suspension)
- Heavy-duty machinery and construction equipment
- Aerospace and defense components
- Home appliances
- Electrical terminals
- Agricultural machinery
- Renewable energy installations (wind turbines, solar panels)
Their compatibility with ISO metric threads makes them suitable for global machinery exports as well.
