Description:Features: Internal tooth washers are designed with teeth on the inside diameter to securely grip the screw head and prevent loosening. Star locking washers provide a tight grip and prevent rotation of fasteners.
Function: These quick locking washers are used to securely fasten screws or bolts in place, preventing them from coming loose due to vibrations or movement. They provide a reliable and durable fastening solution for various applications.
Easy to use: Simply place the internal tooth washer or star locking washer onto the screw or bolt before tightening it into place. The teeth or star design will grip onto the fastener and prevent it from loosening over time.
Multiple Use: These fasteners are suitable for a wide range of applications, including automotive, machinery, furniture assembly, electronics, and more. They are good for use in high-vibration environments where traditional fasteners may come loose.
Notice: When using these lock washers, make sure to choose the appropriate size for the screw or bolt you are using. Ensure that the teeth or star pattern is facing towards the surface being fastened for maximum grip and effectiveness. Regularly check and tighten the fasteners to maintain the security of the connection.
