• nternal Teeth Grip: The sharp inward-pointing prongs dig into the shaft surface when compressed, creating positive mechanical lock that resists loosening from vibration and rotation
• Rigid Core: Formed from hardened steel that maintains its tooth geometry under high clamping force, preventing deformation and ensuring consistent grip through multiple install cycles
• Precision Fit: The uniform inner diameter provides consistent contact with standard shaft sizes, eliminating the play that can cause fasteners to work loose over time
• Bite Retention: The aggressive tooth profile embeds into softer shaft materials, providing reliable holding power even on smooth or lightly lubricated surfaces
• Reusable Hold: Unlike single-use fasteners, the washer can be removed and reinstalled while maintaining its grip, making it suitable for maintenance and adjustment tasks
