Sumitomo 2G00475 Insert Screw T20 Torx M5 Thread

Product Description

The SUMITOMO 2G00475 is a flat-head insert screw designed to secure indexable cutting inserts in compatible toolholders. Using a T20 Torx drive with M5 thread, this screw provides consistent clamping force to hold grooving inserts firmly in place during machining operations. It is part of the SumiTurn B-Groove series and is compatible with AECT-style inserts. At 11.50 millimeters overall length and weighing just 0.01 pounds, the screw is precision-sized for the toolholder geometry it serves. Machinists and tooling technicians working with indexable grooving tools rely on this hardware to maintain accurate insert positioning and repeatable cutting performance.

This insert screw is intended for use with indexable grooving toolholders in the SumiTurn B-Groove series. It fits AECT-compatible inserts with an inscribed circle of approximately 0.856 inches. Typical applications include turning centers and CNC lathes performing external or internal grooving operations in production or job-shop environments. The screw is sold individually but carries a minimum order quantity of 10 units, making it suitable for stocking as a consumable replacement part in any shop running SUMITOMO B-Groove tooling.

Installation Notes

Insert screws of this type are installed and serviced by machinists or tooling technicians using the appropriate T20 Torx key or bit. Always remove the toolholder from the machine spindle or turret and ensure the machine is locked out before servicing insert hardware. Use the correct Torx driver to avoid rounding the drive recess, and do not use impact tools. Replace insert screws at any sign of thread damage, deformation, or stripped drive features to maintain safe and accurate insert retention.
