S-92146A613 2.293" ID x 3.221" OD ASME B18.21.1 Split Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through the split lock design that maintains consistent spring tension under dynamic loads
• Excellent corrosion protection with 18-8 stainless steel construction for long-term reliability in harsh environments
• Optimized dimensional compatibility with 2.293" ID and 3.221" OD specifically engineered for 2 1/4" screw applications
• Enhanced mechanical durability from Rockwell C35 hardness rating that resists deformation under high torque conditions
• Industry-standard compliance with ASME B18.21.1 specifications ensuring consistent performance and interchangeability
• Environmental regulation adherence meeting both RoHS 3 and REACH requirements for global manufacturing applications
• Reliable locking performance through the standard split design that prevents fastener loosening in critical assemblies

Professional Applications & Engineering Value

This heavy-duty split lock washer addresses critical vibration-induced loosening challenges in industrial applications where mechanical integrity is paramount. The 18-8 stainless steel construction provides exceptional corrosion resistance for outdoor equipment, marine environments, and chemical processing facilities where exposure to moisture and corrosive elements would compromise ordinary fasteners. With its substantial 0.440" thickness and Rockwell C35 hardness, this washer maintains spring tension under extreme vibrational stresses common in heavy machinery, power transmission systems, and structural steel connections. The precise 2.293" ID and 3.221" OD dimensions ensure perfect compatibility with 2 1/4" screw applications, eliminating installation issues while providing reliable locking action that prevents costly downtime from fastener failure in critical assembly operations.
