• 【Product Structure】: Features a dual-layer self-locking design that generates irreversible friction, ensuring bolts remain securely fastened even under severe vibration, heavy loads, or thermal expansion.
• 【Wide Range of Applications】: Wedge lock washers are suitable for diverse industries including household furniture, construction and bridge building, manufacturing and processing, shipbuilding, forestry and agriculture, as well as heavy-duty vehicles.
• 【Extra-Large Diameter】: Maximizes clamping force by increasing contact surface between locking teeth and bolt head/nut and workpiece, delivering safer, more reliable retention.
• 【Enhanced Stability】: Unlike traditional washers relying solely on friction, this dual-layer washer utilizes tension to secure bolts subjected to severe vibration and dynamic loads.
• 【Diverse Specifications】: Multiple models available (e.g., M2, M3, M4, M5, M6, M8, etc.) for your selection with confidence.
