Four Corner Cutout Damping Hook Washer | Dual Lug Vibration Damping Washer | Mengpeng HardwareFour Corner Cutout Damping Hook Washer | Dual Lug Anti-Vibration Washer for Light Load Hinges
The four corner cutout damping Hook Washer is a light-duty structural hinge component designed for vibration reduction and load distribution in rotary assemblies. It combines dual lug positioning, hollow cutout geometry and shallow dimple surface treatment to improve stability in low-frequency mechanical environments.
Product Structure Overview
This washer integrates three functional zones: dual anti-rotation lugs, four-corner hollow stress relief structure, and a sparse dimple friction surface. The design focuses on reducing vibration transmission while maintaining stable positioning in light-load hinge systems.
Engineering Function
Dual lugs provide positional locking inside hinge slots
Four-corner cutouts reduce axial stress concentration
Dimple surface reduces direct metal contact wear
Structure improves low-frequency vibration absorption behavior
