Value Collection MS-47 Differential Screw 1/4-28 Hex Socket

Product Description

The VALUE COLLECTION MS-47 is a differential screw designed for use with indexable cutting tool systems. It features a 1/4-28 thread and a 1/8-inch hex socket drive, allowing precise torque application with a standard hex key. The dual-direction thread design - with equal right-hand and left-hand thread lengths - provides the clamping force needed to secure indexable inserts firmly in toolholders. At 0.81 inches overall length and weighing approximately 0.01 pounds, this is a small but critical fastener for maintaining tool integrity during machining operations. Installation is performed by machinists and toolroom technicians.

This differential screw is used in indexable toolholder assemblies found in turning, milling, and boring applications across production and job-shop environments. It is clamp-compatible and conforms to Industry Standard Number MS-47, making it a direct fit for toolholder designs that specify the MS-47 fastener. It is sold individually but subject to a minimum order quantity of 10 pieces per order.

Key Features

• Differential screw design with equal right-hand and left-hand thread lengths for secure insert clamping
• 1/4-28 thread size for compatibility with MS-47 specified toolholders
• 1/8-inch hex socket drive for precise torque application with a standard hex key
• Industry Standard Number MS-47 for direct cross-reference and replacement ordering
• Clamp-compatible hardware for use with standard indexable clamping systems
• Lightweight at approximately 0.01 pounds - minimal mass impact in toolholder assemblies

Compatibility

Designed as a replacement fastener for indexable toolholder assemblies specifying Industry Standard Number MS-47 with a 1/4-28 thread and clamp-compatible hardware.

Installation Notes

Installation is performed by machinists or toolroom technicians. Always ensure the spindle or machine is fully powered down and the toolholder is removed from the machine before replacing fasteners. Use a properly sized 1/8-inch hex key to avoid rounding the socket. Do not over-torque - follow the toolholder manufacturer's fastener torque specifications for the MS-47 screw size.
