Kennametal 1020941 Cap Screw T8 Torx M2.6x0.45

Product Description

The KENNAMETAL 1020941 is a cap screw designed specifically for securing indexable inserts in milling and turning toolholders. It uses a T8 Torx drive and an M2.6 x 0.45 thread pitch, which are the standard fastener specifications found on a wide range of indexable tooling systems. Proper insert clamping depends on using the correct screw geometry and drive type. This screw ensures repeatable seating and consistent clamp force on the insert, which directly affects tool life and surface finish. It is a consumable maintenance item kept on hand by machinists, toolroom technicians, and CNC setup personnel.

This cap screw is used in indexable milling and turning applications wherever an M2.6 x 0.45 insert-retention screw is required. It is a direct-fit fastener for toolholders and milling bodies that call for a T8 Torx insert screw. Having a supply of these screws on hand is standard practice in production machining environments, where a stripped or damaged screw requires an immediate replacement to keep a tool in service. The minimum order quantity is 10 units, with individual package quantity of 1.

Key Features

• T8 Torx drive for positive engagement and reduced cam-out during tightening
• M2.6 x 0.45 thread size matches standard indexable insert pocket fastener specifications
• Compatible with both milling and turning indexable toolholders
• Designed as a direct OEM-style replacement screw for indexable insert retention
• Lightweight at 0.05 pounds per unit, suitable for high-volume stocking

Compatibility

Designed for use with indexable insert toolholders requiring an M2.6 x 0.45 cap screw with a T8 Torx drive, applicable to milling and turning indexable tooling systems.

Installation Notes

Insert screw replacement and torque procedures should be performed by qualified machinists or toolroom technicians. Ensure the spindle or machine is powered down and the tool is secured before servicing insert screws. Use a calibrated T8 Torx driver or torque wrench with the appropriate bit to avoid stripping the drive recess. Do not reuse visibly damaged or deformed screws, as compromised fasteners can lead to insert ejection during cutting.
