Iscar 7002004 Cap Screw M4 X 0.7 Hex Socket Muln

Product Description

The ISCAR 7002004 is a cap screw designed for use with indexable turning toolholders. It features a cylindrical head with a 2.5 mm hex socket drive and an M4 x 0.7 thread. The screw belongs to the Multi-Wedge series and is compatible with the HW 3.0 key driver. At an overall length of 120 mm (approximately 4.72 inches) and a weight of 0.01 pounds, this small-format fastener is a critical retention component that secures cutting inserts within MULN-style toolholders. Installation and replacement are performed by machinists, toolroom technicians, and CNC setup personnel.

This cap screw is used in indexable turning applications where MULN toolholder configurations are employed. It is suited for production turning setups in both job-shop and high-volume manufacturing environments. The screw retains WNMA and WNMG series inserts within the clamping system, making it a routine replacement item during insert indexing or toolholder maintenance. Keeping spares on hand reduces downtime during insert changes.

Key Features

• M4 x 0.7 thread for secure insert retention in MULN toolholders
• Cylindrical head profile fits within toolholder pocket geometry
• 2.5 mm hex socket drive compatible with HW 3.0 key driver
• Multi-Wedge series design for consistent clamping force
• Lightweight at 0.01 pounds — minimal impact on toolholder assembly weight

Installation Notes

This screw is installed and removed by machinists or toolroom personnel using the HW 3.0 hex key driver. Always index or remove the cutting insert before servicing the clamping screw to avoid contact with the cutting edge. Do not overtighten — follow the toolholder manufacturer torque guidance for M4 clamping screws. Replace the screw if thread damage or deformation is observed during routine insert changes.
