S-97093A216 10.7 mm ID x 18.1 mm OD DIN 127B Split Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance prevents loosening under dynamic loads, ensuring long-term joint integrity in high-stress applications.
• Durable black-oxide steel construction provides excellent corrosion resistance, extending service life in harsh industrial environments.
• Rockwell C44 hardness offers reliable spring-back action and maintains locking force without permanent deformation.
• Precision DIN 127B compliance guarantees dimensional accuracy and interchangeability with other standard M10 metric fasteners.
• Optimized split lock design creates continuous tension against the nut and bearing surface for secure anti-loosening performance.
• Wide thickness tolerance (2.0-2.4 mm) accommodates minor surface variations while maintaining consistent clamping pressure.
• Standard metric sizing (10.7mm ID, 18.1mm OD) ensures perfect fit with M10 screw assemblies for streamlined installation.

Professional Applications & Engineering Value

This M10 split lock washer delivers critical vibration-dampening capabilities for machinery, automotive, and structural applications where anti-loosening security is paramount. The black-oxide steel surface treatment combats oxidation in humid or chemically aggressive environments, while the Rockwell C44 hardness ensures the split lock maintains elastic recovery through repeated stress cycles. Engineered to DIN 127B standards, this washer provides reliable performance in heavy-duty assemblies subject to thermal expansion, rotational forces, or impact loads. Its standard split lock design creates axial tension that counters reverse rotation, making it ideal for vibration-resistant fastening in motors, conveyor systems, and equipment frames where safety depends on joint stability.

Specification Summary & Compliance
