Iscar 7003816 Indexable Cap Screw T15 Torx M4x0.7

Product Description

The ISCAR 7003816 is a countersunk-head cap screw designed to secure indexable inserts in compatible toolholders. Using a T15 Torx drive, the screw threads into M4x0.7 tapped seats at a standard torque consistent with indexable toolholder service practice. Overall length is 0.453 inches (11.50 mm). The screw is used in turning applications and is part of the CAMFIX and Heliturn series. Machinists, toolroom technicians, and CNC setup personnel replace these screws during insert changes or when a drive socket has been stripped or cross-threaded.

This cap screw fits C4 SLFN style toolholders and is intended for use with indexable turning inserts. It is a direct replacement hardware item for shops running ISCAR CAMFIX or Heliturn turning systems. The countersunk head profile seats flush with the insert pocket, keeping the clamping geometry consistent across repeated insert changes. Sold individually, it is suited for maintaining a bench stock of critical fasteners.

Installation Notes

Installation is performed by machinists or toolroom personnel during routine insert indexing or replacement. Power down the machine and bring the spindle to a full stop before accessing the toolholder. Use the correct T-15 Torx key driver to avoid stripping the socket. Do not reuse a screw that shows thread damage or a deformed drive socket, as inconsistent clamping torque affects insert seating and machining accuracy.
