Iscar 7003643 Cap Screw T6 Torx M2.5 Mini Tangslot

Product Description

The ISCAR 7003643 is a countersunk cap screw designed to secure indexable inserts in compatible milling toolholders. Built to the Mini TangSlot series standard, this M2.5-thread fastener uses a T6 Torx drive for reliable, low-profile clamping. The countersunk head seats flush against the insert, maintaining accurate positioning during cutting operations. Overall length is 5.25 mm. This screw is a direct replacement hardware component installed by machinists, toolroom technicians, and CNC setup personnel who service indexable milling tooling. Sold individually, with a minimum order quantity of 10 units.

This cap screw is used in indexable milling applications where Mini TangSlot toolholders are in service. It is compatible with ETS, FDN, and SDN toolholder styles and is designed to retain indexable inserts, specifically the LNET 083504-TN-N and LNET 083704-TN-N insert profiles. The T6 Torx drive requires a T-6/3-L or T-6/5 key driver for proper installation. Typical use is in production milling environments where insert changes are performed regularly at the machine or on a presetter bench.
