Discover more about the Metric Internal Locking Washers range
Metric Internal Locking Washers are designed to lock in place after installation. Internal Locking Washers have their teeth on the internal diameter of the washer, giving this component an aesthetic advantage (but a smaller gripping surface) when compared to External Locking Washers.
Components within this range can be manufactured from a full range of materials, including both A2 and A4 Stainless Steel, Aluminium, Brass, Phosphor Bronze and PEEK. Chemical Black Coatings can also be applied to these components in Stainless Steel.
