Sandvik Coromant 5763042 Lock Screw Indexable Toolholders

Product Description

The SANDVIK COROMANT 5763042 is a lock screw designed to secure indexable inserts within compatible toolholders used in CNC turning, milling, and boring operations. This screw applies and maintains the clamping force needed to hold the insert firmly in its pocket during cutting, preventing movement that would compromise dimensional accuracy or surface finish. At 1.26 inches in length and 0.59 inches in both height and width, the 5763042 is a compact, precision-grade fastener. It weighs 0.25 pounds and is sold as a single unit. Machinists and toolroom technicians working with SANDVIK COROMANT indexable tooling systems are the primary users of this replacement hardware.

This lock screw is intended for use with indexable insert toolholders in machining environments where insert retention hardware must be replaced due to wear, stripping, or loss. Indexable insert screws see repeated torque cycling each time an insert is indexed or swapped, making them consumable items in high-volume shops. The 5763042 is compatible with toolholder style 5512 073 as specified by the manufacturer. It is appropriate for use in both production machining and job shop environments running SANDVIK COROMANT tooling.

Installation Notes

Lock screw replacement is a routine toolroom task performed by machinists or toolroom technicians. Before replacing the screw, ensure the machine spindle is stopped, the toolholder is removed from the turret or spindle, and the work area is clear. Use the correct SANDVIK COROMANT torx or hex key driver specified for the toolholder to avoid rounding the screw head. Do not overtighten — follow the toolholder manufacturer's recommended tightening procedure to avoid thread damage or insert cracking.
