Clamping screw Size A, M7, 21 mm, 4-square 8 mm – TECWERK clamping screw for interchangeable holder

The Clamping screw Size A, M7, 21 mm is a spare clamping component for TECWERK interchangeable holders for turning tools, designed to secure the insert holder via an 8 mm square drive.

• Precision spare screw M7
• 21 mm overall length for compact fit
• 8 mm square drive for reliable torque

Secure fastening that keeps production steady

A dedicated M7 clamping screw provides a standardised thread interface that simplifies maintenance and replacement. The 21 mm overall length is suited to compact holders where space is limited, while the 8 mm square drive ensures a secure transfer of torque from the wrench to the clamping element. Engineers benefit from consistent clamping force and predictable assembly behaviour, which together reduce the risk of tool movement and unplanned stoppages.

Designed for quick replacement and compatibility

As a spare part for TECWERK interchangeable holders, this clamping screw supports quick swaps during tool changes and servicing. The part is intended for use with quick-change turning tool holders that incorporate a prism locating feature; this alignment aid ensures repeatable positioning when the screw is reinstalled. Maintaining a small stock of these screws minimises downtime and keeps change-over procedures lean.

Practical workshop handling and inventory benefits

Supplied individually, the component is straightforward to store and identify by its thread and drive dimensions. The 4-sided (square) 8 mm drive type is compatible with common workshop spanners and torque tools, making torque application reliable and maintenance predictable. Keeping matching spare screws avoids improvised repairs and supports a consistent toolholding standard across lathe stations, which is essential for quality and repeatability.
