Stainless Steel DIN127B Spring Lock Washers
Product Overview
DIN127B Spring Lock Washers are essential components in bolted assemblies, designed to prevent unintentional loosening under dynamic loads or vibrations. Known for their split-ring design, these washers provide a continuous radial force and maintain tension between bolted joints, enhancing the overall security of the assembly. Manufactured precisely according to DIN127B standard, they are favored across multiple industries due to their reliability, durability, and resistance to corrosion — especially when made from stainless steel.
At Flybear Fastener, we offer high-quality DIN127B Spring Lock Washers tailored to meet various industrial needs, available in various sizes and grades of stainless steel. Our products undergo stringent quality checks to meet international standards, ensuring lasting performance even in the harshest environments.

Material Information & Manufacturing Process
Our DIN127B Spring Lock Washers are crafted from top-grade austenitic stainless steel, primarily SS304 and SS316. These grades are selected for their outstanding corrosion resistance, mechanical strength, and temperature tolerance.
Manufacturing Process:
- Material Selection & Inspection – High-purity stainless steel certified for mechanical applications.
- Cold Forming – Precision forming the washer via stamping and coiling processes.
- Heat Treatment (optional) – To achieve optimal hardness and elasticity where required.
- Surface Finishing – Passivation or plain finish to improve corrosion resistance.
- Quality Inspection – Rigorous dimensional and performance testing.
This meticulous process ensures each washer meets dimensional ISO tolerances and enhances its long-term performance.
Industries & Common Applications
Stainless steel DIN127B Spring Lock Washers are extensively used in:
- Automotive assemblies (engine and suspension systems)
- Aerospace structures
- Renewable energy (wind turbines, solar installations)
- Marine and offshore applications
- Heavy-duty machinery
- Construction and steel structures
- Electrical enclosures and switchgear panels
Their ability to sustain pre-tension under vibration and harsh environments makes them indispensable in critical mechanical and structural assemblies.
