About this item
- An internal tooth locking washer is a vibration-proof fastener component in most mechanical equipment, featuring inward-pointing teeth that bite into both the bolt head and mounting surface. Primarily used in industrial, automotive, and machinery applications to offer fixing, supporting and damping functions.
- Internal Tooth Locking Washers: Size: M5 x 12 x 1.5 mm / 0.2 x 0.47 x 0.06 inch (ID x OD x Thickness); Material: 65 Manganese Steel; Style: Flipped Edge;
- Compared with traditional gaskets, the inward teeth of star locking washers can better bite into both the fastener head and mounting surface, creating prevailing torque to resist easily loosening due to frequent vibrations. Made of sturdy & high-strength 65Mn steel material, features corrosion resistance and oxidation resistance, which can ensure long-term use.
- Ensure the washer fits the fastener shank. Place it directly under the fastener head or nut, with the teeth facing towards the fastener. The flat side contacts the work surface. Tighten the fastener securely. The internal teeth bite into both the fastener and the surface, creating friction to resist loosening from vibration.
- Before purchasing this product, please check the product specifications to ensure that it is the size that suits your needs.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
