Sandvik Coromant 5758639 Torx Indexable Screw

Product Description

The SANDVIK COROMANT 5758639 is a Torx-drive clamping screw designed to secure indexable inserts in compatible toolholders. These small-format fasteners are a critical consumable in any CNC turning or milling setup - a loose or damaged clamp screw compromises insert seating, surface finish, and tool life. The 5758639 weighs approximately 0.02 pounds per piece, making it a lightweight but essential component. Licensed machinists, toolroom techs, and CNC operators stock these screws to maintain consistent insert clamping force across cutting tools.

This screw is intended for use with indexable toolholders in precision machining environments, including CNC turning centers and milling platforms where replaceable carbide or cermet inserts are used. The Torx drive format provides better torque transfer and reduced cam-out compared to standard hex drives, which is why it is the preferred fastener style across most modern indexable toolholder systems. It is suited to both production floor and toolroom maintenance applications.

Key Features

• Torx drive design for improved torque transfer and reduced cam-out during insert clamping
• Compatible with toolholder style 3212 020 per supplier specification
• Lightweight at 0.02 pounds per piece - suitable for bulk stocking
• OEM-style replacement to maintain factory clamping performance
• Sold individually; minimum order quantity of 10 units

Compatibility

Specified for use with toolholder style 3212 020. Verify screw thread size and Torx key size against your toolholder documentation before ordering to confirm fitment.

Installation Notes

Indexable clamp screws should be installed by a qualified machinist or toolroom technician. Always power down and lock out the machine spindle before changing inserts or clamp screws. Use the correct Torx key size to avoid rounding the drive recess, and follow the toolholder manufacturer's recommended tightening procedure - do not use impact drivers. Inspect the screw threads and seating surface for damage each time an insert is indexed.
