S-91102A011 0.2" ID x 0.334" OD ASME B18.21.1 Split Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance due to the split lock design that maintains constant tension under dynamic loads
• Enhanced corrosion protection with zinc-plated steel construction for extended service life in harsh environments
• Reliable locking performance ensured by Rockwell C38 hardness that prevents deformation under pressure
• Precise fit for No. 10 screws with 0.2" inner diameter for secure fastening without slippage
• Industry-standard compliance with ASME B18.21.1 specifications for consistent quality and interchangeability
• Environmental regulation compliance meeting RoHS 3 and REACH requirements for safe industrial use
• Optimized dimensions (0.334" OD, 0.047" thickness) providing ideal spring action and space efficiency

Professional Applications & Engineering Value

These split lock washers deliver critical vibration-resistant performance in demanding industrial applications where fastener security is paramount. The zinc-plated steel construction provides essential corrosion resistance for machinery exposed to moisture or chemicals, while the standard split lock design creates continuous spring tension that compensates for thermal expansion and vibration-induced loosening. Engineered with Rockwell C38 hardness, these washers maintain their structural integrity under repeated stress cycles, making them ideal for automotive assemblies, electrical enclosures, and heavy equipment where No. 10 screw fastening requires reliable locking action. The precise dimensional control ensures consistent performance across production runs, reducing maintenance intervals and preventing costly downtime.

Specification Summary & Compliance
