Sumitomo 2G00108 Insert Screw T20 Torx M5 Thread

Product Description

The SUMITOMO 2G00108 is a T20 Torx insert screw designed to secure indexable inserts in milling cutter toolholders. With an M5 thread and a flat head profile, this fastener provides consistent clamping force on replaceable carbide inserts during milling operations. The overall length measures 13 millimeters. It is a consumable hardware component replaced as part of routine tooling maintenance by machinists and CNC setup technicians working with indexable milling systems.

This insert screw is used in metalworking and machining environments where indexable milling cutters are the primary material removal tool. It is suited for production shops, job shops, and maintenance machining operations. Compatible insert geometries include the SNEX 156612DP and SNMX 120412DP, covering inserts with inscribed circle diameters of 0.500 inches and 0.625 inches. This screw is installed whenever an insert is indexed to a fresh cutting edge or replaced entirely.

Key Features

• T20 Torx drive for precise torque application and reduced cam-out risk
• M5 thread size for secure engagement in indexable milling cutter pockets
• Flat head profile seats flush against insert seating surfaces
• 13 millimeter overall length compatible with standard insert clamp pocket depths
• Compatible with SNEX 156612DP and SNMX 120412DP insert geometries

Compatibility

Confirmed compatible with SNEX 156612DP and SNMX 120412DP indexable inserts. Suitable for inserts with inscribed circle diameters of 0.500 inches and 0.625 inches in milling cutter toolholders requiring an M5 insert screw.

Installation Notes

Insert screw replacement is performed by machinists or tooling technicians during insert indexing or changeover. The machine spindle must be fully stopped and the tool removed from the spindle or secured in a tool block before servicing. Use a calibrated T20 Torx driver or torque wrench with the appropriate bit; refer to the toolholder manufacturer's specified clamp torque value for M5 insert screws. Inspect the threaded pocket for damage or debris before installing a replacement screw.
