Tesa Brown Sharpe 599-8940 Depth Gage Mounting Collet

Product Description

The TESA BROWN SHARPE 599-8940 is a depth gage indicator mounting collet designed to secure a dial indicator to the rod assembly of a dial depth gage. The collet features a 3/8 inch base hole diameter and a 9/16-28 rod thread size, providing a precise, repeatable connection between the indicator and the gage base. Weighing just 0.05 pounds, this compact component is a direct replacement part for technicians performing maintenance or rebuilding depth gage assemblies. Machinists, toolroom technicians, and quality control inspectors working with dial depth gages will find this collet an essential service component.

This mounting collet is intended for use with dial depth gages in metrology and quality inspection applications. It is suited for shop floor environments, toolrooms, and inspection departments where dial depth gages are used to measure step depths, slot depths, and shoulder heights on machined workpieces. The 9/16-28 thread specification and 3/8 inch base hole diameter make it compatible with standard dial depth gage configurations that call for this collet interface.

Key Features

• 3/8 inch base hole diameter for accurate indicator seating
• 9/16-28 rod thread size for secure connection to depth gage rod assembly
• Lightweight at 0.05 pounds, minimizing added mass to the gage assembly
• Designed for use with dial depth gages as a replacement or spare component
• Compact design suited for toolroom and inspection department use

Compatibility

Designed for use with dial depth gages requiring an indicator mounting collet with a 3/8 inch base hole diameter and 9/16-28 rod thread size.

Installation Notes

Installation is typically performed by a machinist or metrology technician during gage assembly or repair. Before servicing, ensure the depth gage is removed from any active measurement setup and the indicator is fully disengaged. Thread the collet onto the gage rod by hand first to confirm thread engagement before applying any tool torque. Follow the gage manufacturer's assembly documentation to ensure proper indicator alignment and clamp force.
