Seco 75012063 Cap Screw Indexables Hex M6 Quattromill

Product Description

The SECO 75012063 is a hex-drive cap screw designed to secure indexable inserts and cassettes in compatible milling toolholders. Manufactured from steel, this M6-threaded fastener measures 20 millimeters in overall length and is driven with a T09P-3 key. It is part of the QuattroMill series and is used by machinists and toolroom technicians to maintain proper insert seating and clamping force in face mills and shell mills. At 0.02 pounds, it is a lightweight but critical component whose condition directly affects cutting performance and insert security.

This cap screw is intended for use with QuattroMill face mills and shell mills that use cassette-style insert mounting. It is a replacement or spare fastener for production environments where worn, stripped, or lost screws need to be swapped out quickly to minimize downtime. The M6 thread size and T09P-3 drive specification narrow fitment to specific SECO toolholder configurations, so confirming the drive and thread before ordering is recommended.

Key Features

• Hex drive type requires T09P-3 key for installation and removal

Installation Notes

Installation and replacement of indexable clamping screws should be performed by a qualified machinist or toolroom technician with the correct T09P-3 hex key driver. Before replacing the screw, ensure the spindle is fully stopped, locked out, and the toolholder is secured in a vise or fixture. Do not substitute a driver that does not match the T09P-3 specification, as an improper fit can strip the screw head or damage the cassette pocket. Inspect the mating threads in the toolholder body for wear or contamination before installing the new screw.
