Iscar 7060121 Cap Screw T20 Torx 8-32 Thread Se Toolholder

Product Description

The ISCAR 7060121 is a countersunk cap screw designed specifically for securing indexable inserts in threading toolholders. Part of the IscarThread series, this screw features an 8-32 thread size and a T20 Torx drive interface, requiring a T-20/5 key or driver for installation. At 0.5827 inches overall length (14.80 mm), it is engineered to seat flush when torqued into SE-style toolholder bodies. This hardware is a direct replacement component for technicians performing insert changes or rebuilding threading toolholder assemblies in production turning and threading applications.

This cap screw is used in threading operations on CNC lathes and turning centers where SE-style toolholders are employed. It is the correct retention fastener for a wide range of ISCAR indexable threading inserts in the IscarThread series, covering both external and internal threading profiles across multiple thread forms including UN, ACME, and ABUT. Machinists and toolroom technicians performing routine insert indexing or toolholder maintenance will use this screw as the standard clamping hardware.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians during insert indexing or replacement procedures. Power down the machine and ensure the spindle is locked before accessing the toolholder. Use only a T-20/5 Torx key driver to install or remove this screw — substituting an incorrect driver size risks stripping the drive recess. Follow the toolholder manufacturer torque specifications for insert clamping screws when available.
