What Is a Tangless Insert?
A tangless insert is a type of insert screw (female thread reinforcement, reinforcement part) that lacks tangs.
Conventional insert screws feature tangs that need to be removed after being inserted into the female thread for reinforcement. The absence of tangs in tangless inserts leads to various cost reductions and a significant decrease in defects caused by the insertion process.
Uses of Tangless Inserts
Tangless inserts are used to reinforce female threads. They are inserted using a specialized tool that grips the inserts with its jaws. To insert a tangless insert, a hole is drilled in the light metal or resin intended for the female thread, and the insert is rotated into place. These inserts can be easily removed by using the tool to turn them in the opposite direction of insertion.
Features of Tangless Inserts
- No Need to Remove Tangs: Traditional insert screws come with tangs that must be removed after insertion. These removed tangs can become mixed with equipment, potentially causing malfunctions.
- No Directionality: Tangless inserts lack directional characteristics, which eliminates the need to check the orientation of tangs during insertion. This reduces the time required for insertion.
- No Damage to Base Metal: The ease of insertion and removal of tangless inserts minimizes the risk of damaging the base material where the insert is placed.
