Seco 02441041 Lock Screw TP7 Torx Plus M2.2 Thread

Product Description

The SECO 02441041 is a countersunk lock screw designed to secure indexable inserts in drilling toolholders. The M2.2 thread size and TP7 Torx Plus drive ensure precise engagement with insert clamping seats, reducing the risk of screw cam-out or insert movement during cutting operations. At 5.10 millimeters in overall length, the screw is sized for compact insert pockets common in drilling applications. This fastener is a direct replacement or service component used by machinists and tooling technicians maintaining indexable drilling tools on CNC and manual machines.

This lock screw is intended for indexable drilling toolholders that use M2.2 threaded insert clamping screws with a TP7 Torx Plus drive. It suits production and job-shop environments where indexable insert tooling sees regular insert changes and screw replacement is part of routine toolholder maintenance. Correct screw torque is essential to insert seating and should follow the toolholder manufacturer's torque specification for M2.2 insert screws.

Key Features

• TP7 Torx Plus drive resists cam-out during insert clamping
• M2.2 thread size matches standard indexable drilling insert pockets
• Countersunk head type seats flush within insert clamping geometry
• 5.10 mm overall length sized for compact drilling insert seats
• Compatible with indexable insert hardware for drilling applications

Compatibility

Designed as an OEM-style replacement lock screw for indexable drilling toolholders requiring an M2.2 thread, TP7 Torx Plus drive, countersunk insert clamping screw.

Installation Notes

Installation is performed by tooling technicians or machinists during insert indexing or replacement. Power down and lock out the machine spindle before accessing the toolholder. Use a calibrated TP7 Torx Plus key or torque wrench adapter and apply the insert clamping torque specified by the toolholder manufacturer for M2.2 screws. Do not reuse visibly worn or damaged lock screws, as compromised threads can allow insert movement under cutting loads.
