Kennametal 2637762 Torx Plus Cap Screw M2.5 X 0.45

Product Description

The KENNAMETAL 2637762 is a Torx Plus drive cap screw designed specifically for securing indexable inserts in cutting tool holders and tooling assemblies. With an M2.5 x 0.45 thread specification, this screw provides the precise clamping force required to hold carbide inserts firmly in place during turning, milling, or boring operations. At 0.0154 pounds per unit, it is a lightweight but critical fastener in any indexable tooling system. Machinists, toolroom technicians, and CNC setup personnel rely on correct insert screws to maintain insert positioning and prevent premature insert movement under cutting loads.

This cap screw is intended for use in metalworking and machining environments where indexable insert toolholders require dedicated hardware. It is suited to applications in production turning, milling, and similar metal-removal operations where indexable carbide, cermet, or coated inserts are mounted to tool bodies. The Torx Plus drive type allows for higher torque transfer compared to standard hex drives, reducing the risk of screw head damage during tightening and loosening cycles in high-production settings.

Key Features

• Torx Plus drive for improved torque transfer and reduced cam-out during insert changes
• M2.5 x 0.45 thread size engineered for indexable insert clamping applications
• Lightweight construction at 0.0154 pounds per unit
• Designed for compatibility with indexable insert toolholders requiring cap screw hardware
• Sold individually with a minimum order quantity of 10 units

Compatibility

Designed as a replacement cap screw for indexable insert toolholders that require an M2.5 x 0.45 Torx Plus drive insert screw. Verify thread size and drive type against your specific toolholder documentation before installation.

Installation Notes

Insert screws should be installed by a qualified machinist or toolroom technician familiar with indexable tooling systems. Always use the correct Torx Plus driver bit sized for the screw head to avoid damage during tightening. Follow the toolholder manufacturer torque guidance where available, and inspect threads for wear or damage before reuse. Replace screws that show signs of thread stripping, head deformation, or corrosion.
