Sumitomo 2G00490 Indexable Cap Screw T6 Torx M2x0.4

Product Description

The SUMITOMO 2G00490 is a flat-head cap screw designed to secure indexable inserts in SumiDrill drilling toolholders. It uses a T6 Torx drive and an M2 x 0.4 thread pitch, providing consistent clamping force on replaceable cutting inserts during drilling operations. The flat head profile sits flush with the toolholder pocket, keeping the cutting geometry unobstructed. At 4.30 mm overall length and 0.05 pounds per unit, this is a precision fastener intended for CNC and manual drilling setups where insert retention directly affects hole quality and tool life.

This cap screw is used in metalworking and machining environments wherever SumiDrill indexable drill bodies require insert replacement or maintenance. It is a standard consumable for machinists and toolroom technicians who regularly cycle inserts on drilling operations. The M2 x 0.4 thread size and T6 Torx drive are specific to the SumiDrill series insert pocket design. Sold individually per package, with a minimum order quantity of 10 units, making it practical to stock as a shop supply item alongside replacement inserts.

Installation Notes

Installation is performed by machinists or toolroom technicians during indexable insert changes. Always power down and lock out the machine spindle before servicing any toolholder. Use a calibrated T6 Torx driver or key and follow the toolholder manufacturer torque specifications for M2 insert screws. Inspect the screw threads and pocket threads for damage before reinstalling, and replace screws that show signs of galling or deformation.
