Sandvik Coromant 5771031 Indexable Insert Screw

Product Description

The SANDVIK COROMANT 5771031 is a replacement screw designed to secure indexable inserts on cutting tool holders. These small-diameter clamping screws are a critical consumable in precision machining operations, holding inserts firmly in place during turning, milling, or boring applications. When an insert screw strips, breaks, or goes missing, machining operations stop until a replacement is in hand. The 5771031 is the OEM part number for this screw, ensuring correct thread form, head geometry, and torque capacity for SANDVIK COROMANT tooling systems. Weighing 0.25 pounds per package, this is a stock-up item for any shop running SANDVIK indexable tooling.

Indexable insert screws are used wherever SANDVIK COROMANT indexable toolholders are in service — CNC turning centers, milling machines, boring bars, and similar metal-cutting equipment in production and job-shop environments. Machinists, toolroom technicians, and CNC setup personnel are the primary installers. Keeping a supply of insert screws on hand prevents unplanned downtime when screws are damaged during insert changes or lost during maintenance.

Installation Notes

Insert screw replacement is performed by machinists or toolroom technicians using the correct Torx or hex key driver specified by the toolholder manufacturer — do not substitute driver sizes, as rounding the screw head will prevent proper torque and clamp force. Always de-energize the machine and engage the spindle lock before servicing a toolholder on the machine. Do not over-torque insert screws; refer to the toolholder documentation for the recommended procedure. Replace screws at the first sign of thread damage or head deformation to avoid insert movement during cuts.
