Sandvik Coromant 5763139 Cap Screw Torx Plus M3.5

Product Description

The SANDVIK COROMANT 5763139 is a cap screw designed for securing indexable inserts in toolholders used in CNC turning, milling, and boring operations. It features a Torx Plus drive type and an M3.5 thread size, providing reliable clamping force and resistance to cam-out during insert changes. This screw is an OEM-grade replacement component used by machinists and toolroom technicians to maintain cutting tool assemblies. The M3.5 thread and Torx Plus interface are engineered for the tight tolerances required in precision indexable tooling systems.

This cap screw is used in industrial machining environments where indexable insert toolholders require periodic maintenance and hardware replacement. It is suited for production shops, job shops, and toolrooms running turning centers, machining centers, or manual lathes. Technicians replace these screws when existing hardware shows wear, stripping, or damage that could compromise insert seating and cutting performance. The screw is compatible with toolholder assemblies that follow industry standard 5513 020-30 specifications.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the toolholder and insert pocket are clean and free of chips or debris before seating the screw. Use a calibrated Torx Plus driver or bit to avoid rounding the drive interface. Do not overtighten — follow the torque specifications provided in the toolholder manufacturer documentation, as no torque value is specified in the available product data.
