Sandvik Coromant 5763258 Cap Screw Torx Plus M4

Product Description

The SANDVIK COROMANT 5763258 is a Torx Plus drive cap screw designed for securing indexable inserts in cutting tool assemblies. It uses an M4 thread and is engineered to meet the dimensional and torque requirements that keep indexable tooling systems running precisely during machining operations. This screw is a direct-fit replacement or spare component for adapters and toolholders that rely on the ISO 5513 standard. Machinists, toolroom technicians, and CNC operators install these screws when performing insert changes or rebuilding worn tooling assemblies. The Torx Plus drive geometry distributes clamping force evenly and resists bit cam-out during tightening.

This cap screw is used in metalworking environments where indexable insert tooling is employed, including turning, milling, and boring applications. It is suited for production and job-shop settings using toolholders and adapters that accept M4 Torx Plus clamping screws per the ISO 5513 standard. It applies to both manual insert changes at the machine and bench-level toolholder maintenance. Sold individually per package, with a minimum order quantity of 10 units, making it practical to keep a working stock on hand for high-turnover insert applications.

Key Features

• M4 thread size compatible with ISO 5513 standard indexable tooling systems
• Torx Plus drive reduces cam-out risk and extends key life compared to standard hex drives
• Designed for adapter hardware compatibility in indexable insert clamping assemblies
• Industry standard number 5513 021-04 for cross-reference and replacement sourcing
• Lightweight at 0.25 pounds per package, minimizing handling impact during tool changes

Compatibility

Designed as an OEM-style replacement cap screw for indexable toolholders and adapters that accept M4 Torx Plus clamping screws per ISO 5513 standard reference 5513 021-04.

Installation Notes

Installation is performed by toolroom technicians or machinists during indexable insert changes or toolholder maintenance. Always power down and lock out the machine spindle before servicing any cutting tool assembly. Use the correct Torx Plus key rated for the M4 screw size to avoid damaging the drive recess. Do not substitute a standard Torx key for a Torx Plus recess, as the fit geometry differs and can damage the screw head.
