Key Features & Benefits at a Glance
- Superior vibration resistance prevents loosening under dynamic loads, ensuring long-term joint integrity
- Excellent corrosion resistance from 18-8 stainless steel construction for reliable performance in harsh environments
- Precision dimensional fit with 0.2" ID specifically engineered for No. 10 screws
- Enhanced durability with Rockwell C35 hardness for repeated use without deformation
- Industry-standard compliance with ASME B18.21.1 ensures consistent quality and interchangeability
- Environmental responsibility with full RoHS 3 and REACH compliance for global manufacturing applications
- Optimal spring tension from standard split design provides consistent locking force across thermal cycles
Professional Applications & Engineering Value
These 18-8 stainless steel split lock washers deliver critical vibration-resistant fastening solutions for demanding industrial environments. The standard split lock washer design creates continuous spring tension that compensates for thermal expansion, vibration-induced loosening, and material relaxation - common failure points in machinery, automotive assemblies, and electrical enclosures. With 0.2" ID precision sizing for No. 10 screws and 0.35" OD providing optimal bearing surface, these washers maintain clamp load integrity while the stainless steel composition resists chemical exposure and galvanic corrosion. Ideal for industrial maintenance, OEM equipment manufacturing, and applications requiring reliable locking performance without periodic retightening.
Specification Summary & Compliance
Manufactured to ASME B18.21.1 dimensional standards with precise 0.2" inner diameter, 0.35" outer diameter, and 0.056" thickness specifications. These split lock washers maintain Rockwell C35 hardness for consistent performance and meet critical regulatory requirements including RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance with current SVHC declarations. The inch system measurement ensures compatibility with North American fastener standards while the 18-8 stainless steel material provides mechanical properties suitable for most industrial applications.
