Seco 02830450 Insert Screw T08P Hex Drive M2.7 Thread

Product Description

The SECO 02830450 is a countersunk insert screw designed to secure indexable cutting inserts in milling toolholders. It features a T08P Torx drive and M2.7 thread, providing reliable clamping force and precise insert positioning during milling operations. The countersunk head profile sits flush within the toolholder pocket, reducing interference with chip flow. At 8.5 millimeters overall length, this screw fits the geometry of Square T4-08 series toolholders. Installation and replacement are handled by HVAC machinists and toolroom technicians maintaining CNC milling setups.

This insert screw is intended for use in milling applications with indexable toolholders in the R217.94 series and Square T4-08 family. It is a consumable hardware component replaced routinely during insert indexing or when screw threads show wear from repeated torquing cycles. The screw is sold individually per package with a minimum order quantity of 10 units, making it suitable for stocking at the machine or in a toolroom crib for high-frequency milling operations.

Key Features

• T08P Torx drive for positive engagement and reduced cam-out during tightening
• M2.7 thread size matched to Square T4-08 series toolholder insert pockets
• Countersunk head profile minimizes obstruction in the cutting zone
• 8.5 mm overall length engineered for R217.94 toolholder geometry
• Designed for milling indexable insert applications

Compatibility

Compatible with SECO R217.94 series toolholders and Square T4-08 series indexable milling toolholders requiring an M2.7 insert screw with T08P drive.

Installation Notes

Installation is performed by a machinist or toolroom technician during insert indexing or replacement. Power down and de-energize the machine spindle before servicing any toolholder hardware. Use a calibrated T08P Torx key and follow the toolholder manufacturer torque specification documented in the toolholder manual. Inspect screw threads for wear or damage before each reuse, and replace screws that show signs of thread deformation.
