"Wedgelock” is a self locking feature that enhances the integrity of fastener joints by reducing the probability of the threaded joint becoming loose.
A plastic pellet is compressed into a precision hole that is drilled through the thread to a depth just below the minor diameter and at a specific location on the threaded portion of the bolt.
The locking feature is achieved by the resistance between the pellet and the nut or the other threaded part. A wedge effect having been created in the threaded joint assembly which creates resistance to turning and generates a high prevailing torque condition.
Nylon 66 is a typical material that is used in Wedgelock applications although other suitable materials can be used to suit the material and application.
Ideal for short thread length applications.
