Sandvik Coromant 5757257 Cap Screw M8 Torx Plus

Product Description

The SANDVIK COROMANT 5757257 is a cap screw designed for use with indexable cutting tool assemblies. It features a Torx Plus drive type and an M8 thread size, providing a secure and precise clamping connection between indexable inserts and their toolholders. These screws are a critical component in maintaining insert seating integrity during machining operations. Proper fastening torque and screw condition directly affect insert stability and cutting performance, making periodic inspection and replacement a standard part of toolholder maintenance for machining professionals.

This cap screw is intended for use in toolholder applications where indexable inserts require a dedicated clamping screw. It is commonly installed during insert changes on turning, milling, and boring toolholders that accept M8 Torx Plus fasteners. The part carries industry standard number 174.3-821, which can aid in cross-referencing with compatible toolholder documentation. Machinists and tool crib personnel working with SANDVIK COROMANT and compatible indexable tooling systems will encounter this screw type regularly during routine insert indexing and replacement procedures.

Compatibility

Designed for use with indexable toolholders requiring an M8 Torx Plus cap screw. Hardware compatibility is listed as toolholder applications. Verify toolholder documentation to confirm screw specification before ordering.

Installation Notes

Installation is performed by machinists or tool crib technicians during indexable insert changes. Always ensure the toolholder pocket and screw threads are clean and free of chips or debris before installing a new screw. Use a calibrated Torx Plus driver of the correct size to achieve proper seating without over-torquing. Damaged or deformed screws should be replaced immediately, as a compromised clamping screw can lead to insert movement during cutting.
