Spi 20-852-0 Thread Conversion for Agd Dial Indicators

Product Description

The SPI 20-852-0 is a thread conversion accessory designed for use with AGD dial indicators. Machined from steel, this adapter allows a drop indicator to be mounted or repositioned using a different thread interface, expanding the range of setups available to machinists, toolmakers, and quality control technicians. The shank diameter measures 0.2 inches, making it compatible with standard AGD indicator mounting arrangements. This type of accessory is a common requirement in precision measurement setups where thread compatibility between the indicator and its holder or stand must be matched exactly.

This thread conversion is suited for machine shop, metrology, and quality inspection environments where AGD-style dial indicators are mounted on surface plates, magnetic bases, or transfer stands. It is typically used when the existing thread on a drop indicator does not directly match the mounting point, allowing the technician to adapt without replacing the indicator or the fixture.

Compatibility

Designed for use with AGD dial indicators requiring thread conversion at the shank or mounting interface.

Installation Notes

Installation is typically performed by a machinist or metrology technician using hand tools. Before making any adjustments to a mounted indicator setup, ensure the indicator is removed from any live or moving machinery. Thread adapters should be seated fully and checked for secure engagement before applying indicator load. Follow shop safety protocols when working near precision measurement equipment.
