Iscar 7000992 Cap Screw T10 Torx M3.5x0.6 HM90 Milling

Product Description

The ISCAR 7000992 is a countersunk cap screw designed to secure indexable inserts in milling toolholders. Part of the Helialu series, this fastener features a T10 Torx drive and an M3.5x0.6 thread for precise, repeatable clamping force in insert-retention applications. With an overall length of 0.3445 inches (8.75 mm), the 7000992 is a direct replacement hardware component used by machinists and toolroom technicians to maintain insert seating integrity during high-speed milling operations. Its countersunk head profile seats flush with the toolholder pocket, keeping the cutting geometry consistent and unobstructed.

This cap screw is intended for use in milling applications using HM90-style toolholders within the ISCAR Helialu system. It is compatible with the HM90 EAL32 toolholder style and is used to clamp indexable inserts in the HM90 AXCR family. Typical install scenarios include insert changes at the machine tool or in the toolroom during scheduled maintenance. A T-10 or T-51 key driver is required for proper installation.

Installation Notes

Installation is performed by machinists or toolroom technicians during insert indexing or replacement. Ensure the milling cutter or toolholder is removed from the spindle and fully secured before servicing inserts. Use a calibrated T-10 Torx driver to achieve consistent clamping without overtorquing the screw. Inspect threads and the screw head for wear before reinstallation, and replace any fastener that shows signs of stripping or deformation.
