Kennametal 1549256 Cap Screw Indexables T10 Torx

Product Description

The KENNAMETAL 1549256 is a cap screw designed to secure indexable inserts in cutting tool holders and tooling bodies. This fastener uses a T10 Torx drive, which provides higher torque transmission and reduced cam-out compared to hex drives. It is a direct-fit clamping screw intended for use in CNC machining, turning, milling, and boring applications where indexable carbide inserts must be held precisely under cutting loads. Machinists and tooling technicians rely on this style of screw to maintain insert seating and repeatability at the pocket. The package quantity is one piece per unit.

This cap screw is used in metalworking and machining environments, typically in production shops, job shops, and maintenance toolrooms. It is the correct fastener type when replacing worn or damaged clamping screws on indexable toolholders. The T10 Torx drive requires the appropriate T10 key or bit driver during installation. Keeping spare indexable clamping screws on hand reduces downtime when a screw strips or is lost during an insert change.

Key Features

• T10 Torx drive for positive engagement and reduced cam-out during tightening
• Designed for compatibility with indexable insert hardware
• Cap screw style provides a low-profile clamp point within the insert pocket
• Lightweight at under 0.01 pounds, suitable for bulk stocking in toolrooms
• Sold individually, allowing single-unit replacement without excess inventory

Compatibility

Designed as an OEM-style replacement clamping screw for indexable insert toolholders requiring a T10 Torx drive cap screw.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and fully stop the machine spindle before changing any indexable insert or clamping hardware. Use a calibrated T10 Torx key or bit driver and follow the toolholder manufacturer torque specification for the fastener size. Do not overtighten, as this can damage the screw threads or the insert pocket.
