Sumitomo U104117 Insert Screw Hex Drive Indexable

Product Description

The SUMITOMO U104117 is a hex drive insert screw designed to secure indexable carbide inserts in turning toolholders. This small-format fastener keeps inserts locked in place during machining operations, maintaining precise insert positioning and preventing movement under cutting load. At 0.25 inches in length and 0.25 inches in width, it is sized for compact toolholder insert pockets. Weighing 0.01 pounds, it is a direct replacement-grade hardware component used by machinists and toolroom technicians during insert changes or toolholder rebuilds.

This insert screw is intended for use with indexable turning toolholders that accept hex drive clamping screws. It is a routine consumable in CNC turning operations, where insert screws are replaced periodically due to wear, cross-threading, or damage from insert changes. Shops running high-volume turning programs typically stock these in quantity to minimize downtime during insert indexing. It is sold individually but requires a minimum order of 10 units per transaction.

Key Features

• Hex drive configuration for positive engagement with standard hex keys during insert clamping
• Compact form factor: 0.25 inches length, 0.25 inches width, 0.22 inches height
• Designed for indexable turning toolholder insert pocket hardware
• Lightweight at 0.01 pounds - minimal added mass in toolholder assembly
• Minimum order quantity of 10 units supports shop stocking needs

Compatibility

Designed as an OEM-style replacement insert screw for indexable turning toolholders requiring hex drive insert clamping hardware. Verify thread size and head geometry against the toolholder manufacturer specifications before ordering.

Installation Notes

Insert screw replacement is performed by machinists and toolroom technicians during routine insert indexing or toolholder maintenance. Ensure the machine spindle is stopped and the toolholder is removed from the turret or tool post before servicing. Use the correct hex key size to avoid rounding the drive socket. Do not overtighten - follow the toolholder manufacturer torque guidelines for insert clamping screws.
