Kennametal 1020453 Indexable Insert Cap Screw T20 Torx

Product Description

The KENNAMETAL 1020453 is a T20 Torx cap screw designed to secure indexable inserts in milling and turning toolholders. This small-format fastener is a critical hardware component in indexable cutting tool assemblies, where proper clamping force on the insert directly affects cut accuracy and tool life. Weighing approximately 0.0024 pounds, it is a single-piece replacement screw sold in minimum order quantities of 20. Installation and replacement are performed by machinists, toolroom technicians, and CNC setup personnel as part of routine insert indexing or toolholder maintenance.

This cap screw is used in indexable milling and turning applications where a T20 Torx drive is specified for insert retention. It is suited for production machining environments, job shops, and toolroom settings where indexable toolholders are in continuous use and replacement fasteners must be on hand. Keeping spare cap screws available reduces downtime when a screw is stripped, lost, or damaged during an insert change.

Key Features

• T20 Torx drive for positive bit engagement and reduced cam-out risk during insert changes
• Cap screw style designed for flush or low-profile seating in indexable toolholder pockets
• Compatible with indexable milling and turning toolholders requiring T20 Torx insert screws
• Lightweight single-piece hardware at 0.0024 pounds per screw
• Sold individually per package with a minimum order quantity of 20 units

Compatibility

Designed for use with indexable milling and turning toolholders that accept a T20 Torx cap screw for insert retention. Confirm toolholder specifications before ordering to ensure correct screw size and thread match.

Installation Notes

Insert cap screws should be installed and removed using a calibrated T20 Torx driver or key of the appropriate size to avoid rounding the drive recess. Always power down and lock out the machine spindle before indexing inserts or replacing hardware. Do not reuse visibly damaged or deformed screws, as compromised fasteners can allow insert movement under cutting loads. Follow the toolholder manufacturer's recommended seating procedure for insert clamping.
