Iscar 7000203 Cap Screw M6 X 1 Hex Socket Pcln Heliturn Ld

Product Description

The ISCAR 7000203 is a cylindrical-head cap screw designed specifically for indexable turning toolholders. It features an M6 x 1 thread and a hex socket drive, requiring an HW 2.5 key driver for installation and removal. With an overall length of 0.6575 inches (16.70 mm), this screw seats the cutting insert securely within the PCLN toolholder pocket. It is part of the Heliturn LD series and is intended for use by machinists and toolroom technicians working with indexable turning tools on CNC lathes and manual turning centers.

This cap screw is used in production and job-shop turning applications where PCLN-style toolholders are paired with CNMG and CNMX series inserts. It is a direct replacement hardware component that maintains consistent clamping force on the insert during interrupted and continuous turning cuts. Typical environments include aerospace, automotive, and general metalworking shops running medium to heavy turning operations.

Installation Notes

Installation and replacement of indexable toolholder hardware should be performed by a qualified machinist or toolroom technician. Before changing insert hardware, ensure the machine spindle is fully stopped and the toolholder is removed from the turret or tool post. Use only the specified HW 2.5 hex key driver to seat and tighten the screw. Do not substitute a mismatched driver size, as this can damage the socket recess and compromise insert clamping integrity.
