Kennametal 1021375 Torx Screw Indexable Inserts

Product Description

The KENNAMETAL 1021375 is a Torx-drive retention screw designed to secure indexable inserts in milling and turning toolholders. These small-format fasteners are a critical component in any indexable cutting system — a stripped, damaged, or missing clamp screw can cause insert movement, poor surface finish, and accelerated toolholder wear. Weighing approximately 0.003 pounds, the 1021375 is a precision hardware item that must be replaced with an exact OEM equivalent to maintain proper insert seating and clamping force.

This screw is used in indexable milling and turning applications where Torx-drive insert retention hardware is required. Machinists, toolroom technicians, and CNC setup personnel stock these screws as consumable service parts because they are subject to wear, cross-threading, and heat fatigue in production environments. Keeping a supply on hand prevents unplanned downtime during insert changes.

Key Features

• Torx drive interface for positive bit engagement and reduced cam-out risk during tightening
• Compatible with indexable insert pockets in milling and turning toolholders
• OEM KENNAMETAL hardware ensures correct thread form, head geometry, and clamp torque characteristics
• Sold individually; minimum order quantity of 10 units supports bench-stock replenishment
• Lightweight at approximately 0.003 pounds — suitable for small-pocket and miniature toolholder applications

Compatibility

Designed for use with indexable milling and turning toolholders that accept Torx-drive insert retention screws. Confirm thread size, head style, and overall length against the existing screw or toolholder documentation before ordering, as multiple screw variants exist across the KENNAMETAL indexable product line.

Installation Notes

Insert retention screws should be installed and removed by qualified machinists or toolroom personnel using the correct Torx bit size to avoid fastener damage. Always verify the pocket and screw threads are clean and free of chips before installation. Use a calibrated torque wrench or screwdriver set to the toolholder manufacturer's specified clamp torque — never overtighten, as this can strip the screw head or damage the insert pocket. Inspect screws at each insert change and replace any fastener showing signs of thread wear, galling, or head deformation.
