Sumitomo 2G00076 Differential Screw M6x1 3mm Hex Socket

Product Description

The SUMITOMO 2G00076 is a differential screw designed for use with indexable cutting tool assemblies. This fastener uses an M6x1 thread and a 3 mm hex socket drive to secure clamping hardware on indexable insert toolholders. At 0.63 inches overall length and a head size of 0.18 inches, the 2G00076 provides precise clamping force when seating carbide or ceramic inserts during machining operations. It weighs approximately 0.05 pounds. Machinists, toolroom technicians, and CNC setup personnel install this type of screw as a standard maintenance or replacement item when servicing indexable tooling systems.

The 2G00076 is used in metalworking and machining environments wherever SUMITOMO indexable toolholders require clamp fastening. Differential screws of this type are common in turning, milling, and boring applications where consistent insert clamping torque and thread integrity are critical to tool life and dimensional accuracy. This screw is sold individually and is suitable for bench-stock replenishment in production machine shops and maintenance toolrooms.

Key Features

• M6x1 thread size for standard indexable toolholder clamp compatibility
• 3 mm hex socket drive for precise torque application with standard hex keys
• Overall length of 0.63 inches for correct clamp seating depth
• Head size of 0.18 inches for proper clamp interface fit
• Lightweight at 0.05 pounds — practical for high-volume bench stock
• Sold as individual unit with a minimum order quantity of 1

Compatibility

Designed as an OEM-style replacement differential screw for SUMITOMO indexable toolholders that use clamp-style insert retention with an M6x1 thread and a 3 mm hex socket drive.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine powered down and all spindle motion stopped before servicing any toolholder. Use a calibrated hex key or torque driver sized for a 3 mm socket to tighten the screw to the insert clamping specification listed in the toolholder manufacturer documentation. Do not cross-thread or over-torque differential screws, as this can damage the clamp bore threads and compromise insert seating. Inspect the screw threads for wear or galling before reinstallation.
