Sandvik Coromant 6289951 Cap Screw Torx Plus Indexable

Product Description

The SANDVIK COROMANT 6289951 is a Torx Plus drive cap screw designed for securing indexable inserts in cutting tool holders. This small-format fastener is a precision replacement component used in CNC and manual machining operations where indexable tooling systems require reliable insert clamping. The Torx Plus drive reduces cam-out risk during tightening and removal, making it well suited for high-cycle tooling environments. At 0.43 inches in length and 0.26 inches in width and height, the 6289951 is engineered to meet the dimensional and torque requirements of compatible indexable tooling systems in line with ISO standard 5513 020-78.

This cap screw is used in metalworking and machining environments where indexable insert holders — such as turning, milling, or boring tool bodies — require periodic insert changes. Machinists and tooling technicians performing insert replacements on the shop floor or in toolroom settings will use this fastener as part of routine tooling maintenance. It is sold individually per package with a minimum order quantity of 10 units, making it appropriate for stocking as a consumable replacement component.

Compatibility

Designed as an OEM-style replacement cap screw for indexable insert tooling systems requiring a Torx Plus drive fastener conforming to industry standard 5513 020-78.

Installation Notes

Installation is performed by qualified machinists or tooling technicians during indexable insert replacement procedures. Before servicing, ensure the machine is powered down, the spindle is locked, and any relevant lockout/tagout procedures are followed per facility safety protocols. Use a calibrated Torx Plus key or driver of the correct size to avoid fastener damage. Do not over-tighten; consult the tool holder manufacturer documentation for torque specifications applicable to this screw size.
