Ultra-dex 968-000-094 Insert Screw M3.5 Thread

Product Description

The ULTRA-DEX 968-000-094 is an M3.5 thread insert screw designed to secure indexable cutting inserts to toolholders and boring bars used in turning, milling, and boring operations. This fastener is a direct replacement component for indexable tooling systems where the clamping screw has worn, stripped, or been lost during insert changes. Sold individually with a minimum order quantity of 10 pieces, it is a standard consumable stocked by machinists, toolroom technicians, and CNC operators who perform routine insert indexing and replacement.

This insert screw is intended for use in indexable cutting tool assemblies across light and heavy machining applications. It fits toolholders that accept M3.5 clamping screws and is a common fastener size found in turning centers, CNC lathes, and milling setups. It is suitable for job shops, production machining environments, and maintenance toolrooms where keeping spare fasteners on hand minimizes downtime during insert changes.

Installation Notes

Insert screws should be installed and removed using the correct Torx or hex key driver supplied or specified by the toolholder manufacturer to avoid cam-out and fastener damage. Always clean the threaded bore in the toolholder pocket before installing a new screw to prevent cross-threading. Torque to the toolholder manufacturer's specification - do not overtighten, as this is a small-diameter fastener. Replacement should be performed with the machine fully stopped and locked out per applicable shop safety procedures.
