Description

The Set Of 5 SK40 / DIN 69872 Pull Stud is a precision-engineered retention knob designed for CNC machines using BT40 tool holders. Identified by its ISO standard name MAS 403, this pull stud forms a critical mechanical link between the machine spindle and the tool holder, ensuring secure and stable clamping during machining operations.

Pull studs are subjected to extremely high clamping forces and spindle speeds, making accuracy, rigidity, and reliability essential. Low-quality pull studs can reduce machine performance and create serious safety risks. A broken pull stud may cause severe damage to the machine and workpiece and may even result in injury to operating personnel.

Our SK40 / DIN69872 Pull Studs are manufactured from special high-strength alloy steel and are properly heat-treated to deliver superior rigidity, wear resistance, and long service life. These pull studs are available in with hole and without hole variants to suit different CNC machine and coolant system requirements.
