Walter 7616720 Torx Plus Drive Screw Indexable Inserts

Product Description

The WALTER 7616720 is a Torx Plus drive clamping screw designed to secure indexable cutting inserts in compatible toolholders and milling or turning bodies. This type of fastener is a consumable component in any shop running indexable tooling systems. The Torx Plus drive geometry provides improved torque transfer and better resistance to cam-out compared to standard Torx drives, which is critical when seating inserts under repeated cutting loads. It corresponds to industry standard number FS2573 and is cataloged under the same designation by the manufacturer.

Indexable insert screws like the 7616720 are used in CNC turning centers, milling machines, and manual lathes wherever mechanical-clamp toolholders require a dedicated fastener to lock inserts in the pocket. Machinists and tooling technicians replace these screws as part of routine tooling maintenance, particularly when thread wear or drive recess damage is observed. Sold individually, this part suits shops that need to restock single fasteners without purchasing a full kit.

Key Features

• Torx Plus drive type for improved torque transfer and reduced cam-out risk
• Conforms to industry standard FS2573 for consistent cross-brand fitment reference
• Lightweight construction at 0.01 pounds, minimizing toolholder mass impact
• Sold as a single unit, allowing precise quantity ordering for maintenance stock
• UNSPSC Code 31161500 for streamlined procurement in standardized purchasing systems

Compatibility

Designed as an OEM-style replacement screw for indexable toolholders and cutting bodies that specify a Torx Plus drive insert-clamping fastener conforming to industry standard FS2573. Verify thread size and shank geometry against your toolholder specification before ordering.

Installation Notes

Installation of indexable insert screws should be performed by a machinist or qualified tooling technician. Ensure the machine spindle is fully stopped and the toolholder is removed from the turret or spindle before replacing the screw. Use a calibrated Torx Plus key of the correct size to avoid rounding the drive recess. Do not exceed the torque value specified in the toolholder manufacturer documentation, as over-torquing can strip the thread or fracture the screw body.
