Seco 00041722 Differential Screw 1/4-28 Turning Indexable

Product Description

The SECO 00041722 is a differential screw designed for indexable turning toolholders. Differential screws use opposing thread directions to generate clamping force, securing the insert firmly without requiring additional fasteners. This screw features a 1/4-28 thread size, an overall length of 0.81 inches, and equal right-hand and left-hand thread lengths of 0.28 inches each. It is compatible with CL-20 clamps and is suited for use in precision turning applications. Licensed machinists, toolroom technicians, and CNC setup personnel are the typical users for this type of hardware.

This differential screw is used in indexable turning setups where reliable insert clamping is essential to surface finish and tool life. It is appropriate for both production and job-shop environments running indexable turning toolholders that accept CL-20 clamp systems. The 1/4-28 thread designation ensures compatibility with the corresponding tapped bores in qualifying toolholder bodies. Industry Standard Number 41722 provides an additional cross-reference point for procurement.

Key Features

• Differential thread design generates clamping force through opposing right-hand and left-hand thread sections
• 1/4-28 thread size fits standard tapped bores in compatible indexable turning toolholders
• Equal right-hand and left-hand thread lengths of 0.28 inches for balanced clamp actuation
• Overall length of 0.81 inches suits standard CL-20 clamp geometry
• Compatible with CL-20 clamp hardware used in indexable turning applications
• Industry Standard Number 41722 supports cross-referencing across procurement systems

Compatibility

Designed for use with CL-20 clamp hardware in indexable turning toolholders that accept a 1/4-28 differential screw. Industry Standard Number 41722 may be used as a cross-reference identifier.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine powered down and the spindle locked. Use the appropriate hex key or driver specified by the toolholder manufacturer to avoid fastener damage. Do not overtighten, as differential screws are designed to generate clamping force through thread engagement, not torque alone. Inspect the screw threads and clamp seating surfaces before installation to ensure no debris or damage is present.
