Kennametal 2213842 Cap Screw TP20 Torx Plus Indexable

Product Description

The KENNAMETAL 2213842 is a cap screw designed for indexable tooling systems used in face mill and shell mill applications. This screw features a TP20 Torx Plus drive, which provides increased torque transfer and reduced cam-out compared to standard Torx drives, keeping inserts firmly seated during heavy cutting operations. It is part of the Screw-On series and is compatible with KSOM toolholder styles. Licensed machinists and toolroom technicians use this fastener to secure indexable inserts during milling operations. At 0.0037 pounds per unit, it is a lightweight but critical component in maintaining insert clamping integrity.

This cap screw is intended for use with indexable face mills and shell mills in the KSOM toolholder family. It is sold individually per package but must be ordered in multiples of 10. Typical applications include securing carbide inserts in production milling environments where consistent clamping force and drive engagement are required across multiple insert pockets. Shops running KSOM-style holders will find this screw a direct-fit hardware replacement.

Compatibility

Designed for use with KSOM-style toolholders and indexable insert hardware in face mill and shell mill configurations. Specific compatible insert grades and body models should be confirmed against KENNAMETAL toolholder documentation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Use a calibrated TP20 Torx Plus key and follow the torque specifications published in the KENNAMETAL toolholder documentation for this screw series — do not substitute a standard Torx driver, as this can damage the drive recess. Always remove the tool from the spindle and ensure the machine is in a locked-out, de-energized state before servicing insert hardware. Inspect the screw threads and seating surface for wear or damage before reinstallation.
