Allied Machine 7247-IP7-1 Cap Screw TP7 Torx Plus 1/8 Thread

Product Description

The ALLIED MACHINE AND ENGINEERING 7247-IP7-1 is a cap screw designed for indexable cutting tools, specifically for use in drilling applications. It features a Torx Plus drive in TP7 size, requiring an 8IP-7 key driver for installation. The 1/8-inch thread size and compact profile make it a direct-fit fastener for securing indexable inserts within compatible toolholders. Part of the T-A series, this screw provides reliable clamping force to keep inserts seated correctly during high-load drilling operations. It is a precision hardware component handled by toolroom staff, machinists, and CNC technicians maintaining indexable tooling assemblies.

This cap screw is intended for use in indexable drilling toolholders that accept the T-A series fastener standard. It is suited for production machining environments where insert changes are frequent and consistent clamping torque is essential for maintaining tool geometry and cut quality. The Torx Plus drive reduces cam-out risk during insert swaps, making it appropriate for high-volume tooling maintenance in job shops, aerospace, and general metalworking facilities. The industry standard number 7247-IP7-1 allows direct cross-referencing with toolholder documentation.

Key Features

• Torx Plus TP7 drive minimizes cam-out and fastener wear during frequent insert changes
• 1/8-inch thread size matches T-A series indexable toolholder specifications
• Compatible with 8IP-7 key driver for proper installation torque
• Designed for indexable drilling applications in production machining environments
• Industry standard number 7247-IP7-1 enables straightforward cross-reference with OEM toolholder documentation

Compatibility

Designed for use with indexable toolholders in the T-A series that accept a 1/8-inch thread cap screw with Torx Plus TP7 drive. Requires an 8IP-7 key driver for installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the toolholder and spindle are fully powered down and the machine is locked out before performing any insert or fastener service. Use only the specified 8IP-7 Torx Plus key driver to avoid stripping the drive recess. Do not reuse visibly damaged or deformed cap screws, as compromised fasteners can cause insert ejection during cutting.
