Kennametal 1099645 Cap Screw Indexable Socket Head

Product Description

The KENNAMETAL 1099645 is a socket head cap screw designed to secure indexable inserts in toolholders, boring bars, and milling cutters used in precision machining operations. This replacement fastener maintains proper insert clamping force to ensure accurate, repeatable cutting performance. The socket head design accepts a hex key drive for controlled tightening in confined toolholder pockets. At 0.004 pounds, the screw is a lightweight but critical component — insert failure and tool runout can often trace back to a worn or damaged clamping screw. Machining professionals and tool crib technicians replace these as part of routine toolholder maintenance.

This cap screw is used in CNC turning, milling, and boring applications wherever KENNAMETAL indexable tooling systems are employed. It is suited for both production floor environments and job shop settings. The screw is sold individually and is intended for shops that stock replacement hardware to minimize downtime when a clamping screw strips or is lost during an insert change.

Key Features

• Socket head configuration accepts standard hex key for tightening in tight toolholder pockets
• Designed as a direct replacement for worn or damaged indexable insert clamping screws
• Lightweight at 0.004 pounds — minimal mass addition to toolholder assembly
• Sold as a single unit for targeted replacement without excess inventory
• UNSPSC Code 31161500 for procurement and catalog classification

Compatibility

Designed as an OEM-style replacement cap screw for KENNAMETAL indexable toolholders and cutting tool bodies that use socket head clamping screws for insert retention.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Remove the toolholder from the machine spindle and ensure the insert pocket is clean and free of chips before seating the new screw. Use the correct hex key size to avoid rounding the socket head. Do not over-torque the screw — follow the toolholder manufacturer torque guidelines for the specific toolholder model being serviced.
