Seco 00041148 Differential Screw 1/4-28 Hex Indexable Turning

Product Description

The SECO 00041148 is a differential screw designed for indexable cutting tool assemblies used in turning applications. It features a 1/4-28 thread size with a hex drive and serves as the clamping fastener that secures indexable inserts or clamps within the toolholder body. The screw measures 0.75 inches in overall length, with a right-hand thread length of 0.31 inches and a left-hand thread length of 0.31 inches. Licensed machinists, toolroom technicians, and CNC setup personnel install this hardware during insert changes and toolholder maintenance. It is compatible with CL-20 clamp hardware.

This differential screw is intended for indexable turning toolholders requiring CL-20 clamp compatibility. Its dual-thread differential design allows the screw to draw the clamp down securely against the insert with controlled clamping force, making it a standard consumable hardware item in production turning environments. It is sold individually per package, with a minimum order quantity of 10 units, making it suitable for stocking as a replacement fastener in toolcrib inventory.

Installation Notes

Installation is performed by machinists or toolroom technicians during insert indexing or toolholder servicing. Ensure the toolholder is removed from the machine or the spindle is locked and power is off before servicing any indexable tooling hardware. Use the correct hex key driver sized for the screw drive to avoid rounding the socket. Do not overtighten differential screws, as the dual-thread design self-limits clamping engagement when properly seated.
