Allied Machine 7619-IP25-1 Cap Screw TP25 Torx Plus 1/2 Thread

Product Description

The ALLIED MACHINE AND ENGINEERING 7619-IP25-1 is a cap screw designed for indexable toolholders used in drilling applications. It features a TP25 Torx Plus drive with a 1/2-inch thread size, providing secure clamping force on indexable inserts during high-stress cutting operations. This screw is part of the T-A Series and is compatible with the 8IP-25 key and driver. Installation and replacement are handled by machinists and toolroom technicians maintaining indexable drilling tool assemblies. The hardened construction and precision thread form ensure consistent seating of indexable inserts across repeated tool changes.

This cap screw is suited for drilling operations in machining environments where T-A Series indexable toolholders are in service. It serves as a direct replacement component when existing screws show wear, stripping, or damage from regular insert changes. Keeping spare cap screws on hand minimizes downtime during insert swaps on production and job-shop floors. The TP25 Torx Plus interface reduces cam-out risk compared to standard hex drives, supporting faster and more reliable insert indexing.

Key Features

• TP25 Torx Plus drive reduces cam-out during insert tightening
• 1/2-inch thread size for secure indexable insert clamping
• Compatible with 8IP-25 Torx Plus key and driver
• Designed for T-A Series drilling toolholders
• Hardened cap screw construction for repeated tool change cycles
• Minimum order quantity of 10 supports stocking for production environments

Compatibility

Designed as an OEM-style replacement cap screw for T-A Series indexable drilling toolholders requiring a TP25 Torx Plus drive and 1/2-inch thread. Compatible with toolholders requiring the 8IP-25 key and driver.

Installation Notes

Installation is performed by machinists or toolroom personnel during routine insert indexing or replacement. Power down and lock out the machine before accessing the toolholder assembly. Use the specified 8IP-25 Torx Plus key or driver to seat and tighten the screw. Do not substitute standard Torx drivers for Torx Plus fasteners, as the interface geometry differs and can damage the drive recess.
