Allied 7255-IP8-1 Cap Screw TP8 Torx Plus M2.5 Drilling

Product Description

The ALLIED MACHINE AND ENGINEERING 7255-IP8-1 is a cap screw designed for indexable cutting tools used in drilling applications. It secures indexable inserts to the tool body, maintaining precise insert positioning under cutting loads. The screw uses a Torx Plus TP8 drive, which requires an 8IP-8 key driver for installation and removal. The M2.5 thread size is standard for this class of indexable tooling. Machinists and tool technicians working with Allied T-A series drilling systems will find this screw is the correct OEM-specified fastener for that platform. It weighs 0.1 pounds.

This cap screw is intended for use with indexable insert tooling in metal-cutting drilling operations, specifically within the Allied Machine and Engineering T-A series system. It is suited for production machining environments where indexable inserts are regularly rotated or replaced. The Torx Plus drive geometry resists cam-out during tightening, which helps maintain consistent clamp force on the insert. Tool room personnel and CNC machine operators performing insert changes will use this fastener as part of routine tooling maintenance.

Key Features

• M2.5 thread size matches OEM indexable tool body specifications for the T-A series
• TP8 Torx Plus drive requires 8IP-8 key driver for precise torque application
• Cap screw design provides secure clamping force to retain indexable inserts
• Compatible with indexable drilling tool inserts as the designated hardware fastener
• Industry Standard Number 7255-IP8-1 for direct cross-reference ordering

Compatibility

Designed for use with indexable insert tooling in the Allied Machine and Engineering T-A series drilling system. Compatible with inserts requiring M2.5 thread cap screws and an 8IP-8 key driver. Refer to tool body documentation to confirm correct screw specification before ordering.

Installation Notes

Installation and removal should be performed by a qualified machinist or tool room technician. Always power down and lock out the machine spindle before changing indexable inserts or insert screws. Use only the specified 8IP-8 Torx Plus key driver to avoid drive recess damage. Do not reuse visibly worn or damaged cap screws, as compromised threads or drive recesses can result in loss of insert clamping force during cutting.
