Seco 02440117 Lock Screw Torx Plus T7P M2.2 X 0.45

Product Description

The SECO 02440117 is a countersunk lock screw designed to secure indexable inserts in threading toolholders. It uses a Torx Plus T7P drive for precise torque transfer and reduced cam-out during tightening. The M2.2 x 0.45 thread pitch and 5.20 mm overall length are sized for compact indexable tooling where insert retention and repeatability are critical. This screw is a consumable component replaced during routine insert changes and is typically handled by machinists and toolroom technicians working with threading toolholders.

This lock screw is used in threading indexable toolholder systems that accept countersunk insert mounting hardware. It is compatible with inserts following the C02205-T07P insert style designation and the 187R insert size classification. Typical applications include CNC turning centers and manual lathes running threading operations where indexable inserts must be locked securely against cutting forces. This part ships individually but requires a minimum order quantity of 10 units.

Compatibility

Designed for use with indexable threading toolholders requiring a countersunk lock screw with M2.2 x 0.45 thread and Torx Plus T7P drive. Compatible with inserts of style C02205-T07P and insert size 187R as stated by the manufacturer.

Installation Notes

Installation is performed by machinists or toolroom technicians during insert indexing or replacement. Ensure the toolholder pocket and insert seating surface are clean and free of chips before seating the insert and engaging the lock screw. Use a calibrated Torx Plus T7P driver and apply only manufacturer-specified torque to avoid thread stripping in the toolholder body. Do not substitute a standard Torx driver for the Torx Plus T7P, as the drive geometry differs and can damage the screw head.
