Walter 5039027 Clamp Screw T9IP Torx Indexable Inserts

Product Description

The WALTER 5039027 is a T9IP Torx clamp screw designed to secure indexable inserts in compatible toolholders. This small but critical piece of cutting tool hardware keeps inserts locked in position during milling, turning, or boring operations. It is manufactured to the dimensional requirements of the F4042 Series and F4080 Series toolholder platforms. The Torx drive interface provides a positive engagement point that resists cam-out during tightening, helping maintain correct clamping force on the insert seat. Machinists and tool room technicians working with WALTER indexable tooling systems select this screw as a direct replacement when hardware is worn, stripped, or lost.

This clamp screw is intended for use in metalworking environments where WALTER F4042 and F4080 Series toolholders are in service. It is compatible with AD.T 1204 indexable inserts and the F4042.11 toolholder style. Typical applications include CNC machining centers, lathes, and manual machines running indexable insert tooling. The screw is sold individually but carries a minimum order quantity of 10 units, making it practical to stock as a service item in tool cribs and machining shops.

Installation Notes

Installation should be performed by a qualified machinist or tool room technician familiar with indexable tooling hardware. Power down and de-energize the machine spindle before servicing any toolholder hardware. Use a calibrated Torx T9IP key or driver to achieve proper seating torque without over-tightening, which can strip the screw or damage the insert pocket. Inspect the insert seat and pocket for chips or debris before installing a new clamp screw.
