Kennametal 1023257 Cap Screw Indexables T7 Torx M2.5x0.45

Product Description

The KENNAMETAL 1023257 is a T7 Torx cap screw designed specifically for securing indexable inserts in screw-on style tooling systems. With an M2.5 x 0.45 thread, this small-diameter fastener provides the clamping force and precise seating required to hold indexable carbide inserts firmly in place during cutting operations. It is sold in packages of 10 and is used by machinists and tooling technicians who maintain or set up indexable milling and turning tool assemblies. Proper screw condition is critical to insert stability, and worn or damaged screws should be replaced promptly to prevent insert movement and tool failure.

This cap screw is applicable to indexable milling and turning tools that use the screw-on insert mounting method. It fits toolholders and cutter bodies requiring an M2.5 x 0.45 thread with T7 Torx drive engagement. The screw-on series design is common in high-precision turning and milling applications where insert repeatability and rigid clamping are essential. Tooling technicians stocking maintenance hardware for CNC lathes and milling centers will typically keep these on hand as consumable replacement fasteners.

Installation Notes

Installation is performed by qualified machinists or tooling technicians during insert changes or toolholder maintenance. Use a calibrated T7 Torx driver or torque wrench with the appropriate bit to seat the screw correctly. Always refer to the toolholder manufacturer torque specification for the insert screw before tightening. Inspect threads for damage or wear before reuse, and replace screws that show signs of galling, stripping, or deformation.
