Kennametal 1020977 Indexable Cap Screw T15 Torx

Product Description

The KENNAMETAL 1020977 is a T15 Torx drive cap screw designed for securing indexable inserts on milling and turning toolholders. This small-format fastener is a critical hardware component in indexable cutting tool assemblies, where insert clamping integrity directly affects cutting performance, repeatability, and tool life. Weighing approximately 0.0022 pounds, the screw is engineered to the dimensional and drive standards required by KENNAMETAL indexable tooling platforms. Installation and replacement are performed by machinists and toolroom technicians as part of routine insert change procedures.

This cap screw is used in CNC and manual machining environments wherever KENNAMETAL indexable milling and turning tools are in service. Insert screws of this type are consumable hardware — they are subject to wear, galling, and breakage during high-cycle insert changes and should be replaced at regular intervals to maintain proper insert seating and clamping force. Keeping a supply on hand minimizes downtime during insert changes on the production floor or in the field.

• Sold individually with a minimum order quantity of 10 units

Compatibility

Designed for use with KENNAMETAL indexable milling and turning toolholders that accept T15 Torx drive insert cap screws. Consult the specific toolholder documentation to confirm correct screw size before ordering.

Installation Notes

Insert cap screws should be installed using a calibrated T15 Torx key or driver. Always follow the toolholder manufacturer's recommended tightening procedure — overtightening can strip the screw or damage the insert pocket, while undertightening causes insert movement during cutting. Inspect the screw threads and drive recess for wear or damage before each insert change and replace the screw if any deformation is present. Keep the screw and insert seating surfaces clean and free of chips before assembly.
