Iscar 7002396 Set Screw Hex Socket 3/8 Inch T490 Helitang

Product Description

The ISCAR 7002396 is a fillister-head set screw designed for securing indexable inserts and toolholder components in precision milling assemblies. It uses a hex socket drive for positive torque transfer and features a 3/8 inch UNF thread (4.00 mm metric equivalent) with an overall length of 25.40 mm (approximately 1.0 inch). This screw is built for use in the Helitang series T490 toolholder system, making it a direct-fit replacement hardware component for face mills and shell mills. Installation and replacement are performed by toolroom technicians and CNC machinists maintaining indexable tooling setups.

This set screw is matched to T490 toolholder configurations used in face and shell milling operations. It is the correct replacement or spare hardware for Helitang series toolholders requiring SR UNF-style set screws. Maintaining the correct clamping hardware is critical to insert seating accuracy and tool life. This screw is appropriate for both initial toolholder assembly and field replacement when clamping hardware shows wear or damage.

Key Features

• Hex socket drive for reliable torque application with standard hex keys
• Fillister head profile designed for recessed seating in T490 toolholder bodies
• 3/8 inch UNF thread (SR UNF style) for precise fit to compatible toolholder thread forms
• Matched to Helitang series face mill and shell mill toolholders
• 25.40 mm overall length for correct engagement depth in T490 hardware

Compatibility

Designed for use with ISCAR Helitang series T490 toolholders configured for face mill and shell mill indexable tooling applications.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Always remove the toolholder from the spindle and ensure the machine is locked out before servicing clamping hardware. Use the correct hex key size for the socket drive to avoid rounding the drive recess. Do not substitute screws of different thread forms or lengths, as improper hardware can affect insert seating and create safety hazards during cutting.
