Hertel 4006150 Torx Screw T20 M5 X 0.8 Indexable Insert

Product Description

The HERTEL 4006150 is a T20 Torx countersunk clamping screw designed to secure indexable inserts in compatible toolholders. It uses an M5 x 0.8 thread and measures 0.45 inches in overall length with a head size of 0.28 inches. The flat point and countersunk head profile provide consistent seating pressure against the insert pocket, keeping the cutting insert locked in position during drilling operations. This type of hardware is a consumable component in indexable tooling systems and is replaced as part of routine toolholder maintenance by machinists and toolroom technicians.

This screw is matched to the HID series indexable insert drill system. It is used in metalworking environments where indexable insert drills are the primary material-removal tool, including production machining, job shop drilling, and toolroom applications. The screw is compatible with the HPMT125812-GP insert, making it a direct hardware replacement when screws are lost, stripped, or damaged during insert changes. Minimum order quantity is 5 pieces, sold individually per package.

Installation Notes

Installation is performed by toolroom technicians or machinists during indexable insert changes or toolholder maintenance. Use a calibrated T20 Torx driver or torque wrench with the appropriate Torx bit to seat the screw. Always ensure the insert pocket and screw threads are clean and free of chips before installation. Do not cross-thread or overtighten, as this can strip the screw or damage the toolholder pocket.
