Sandvik Coromant 5758580 Cap Screw Torx Plus 1/4 in Thread

Product Description

The SANDVIK COROMANT 5758580 is a Torx Plus drive cap screw designed for securing indexable inserts in toolholders used in CNC turning, milling, and boring applications. This replacement screw features a 1/4 inch thread size and is manufactured to maintain consistent clamping force on carbide inserts during high-speed cutting operations. At 0.71 inches in length and 0.25 pounds, it is a direct-fit fastener engineered to the dimensional and torque tolerances required by precision indexable tooling systems. Machinists, toolroom technicians, and CNC setup personnel install these screws as part of routine insert changes and toolholder maintenance.

This cap screw is used in metalworking environments where indexable insert toolholders require replacement clamping hardware. It is suited for production machine shops, tool cribs, and maintenance operations where worn or damaged insert screws need fast, like-for-like replacement. The Torx Plus drive reduces cam-out during tightening, which is critical when applying the precise torque needed to seat carbide inserts correctly without cracking the insert or damaging the toolholder pocket. This part corresponds to industry standard number 3212 030-502.

Key Features

• Torx Plus drive reduces cam-out and allows accurate torque application during insert clamping
• 1/4 inch thread size matches standard indexable toolholder insert screw specifications
• 0.71 inch length provides correct engagement depth for compatible toolholder pockets
• Designed as a direct OEM-style replacement for worn or missing clamping screws
• Industry standard number 3212 030-502 for cross-reference identification

Compatibility

Designed for use with indexable insert toolholders requiring a Torx Plus drive cap screw with a 1/4 inch thread. Compatible hardware type is toolholder as specified by the manufacturer. Verify thread size and drive type against your existing toolholder documentation before ordering.

Installation Notes

Installation is performed by toolroom technicians or CNC machine operators during insert indexing or replacement. Use a calibrated Torx Plus driver or insert key and apply only the torque value specified in your toolholder manufacturer documentation — over-torquing can crack the carbide insert or damage the threaded pocket. Inspect the toolholder pocket and thread bore for debris or damage before installing a new screw. Do not substitute a standard Torx driver for a Torx Plus drive, as the drive geometry differs and can strip the screw head.
