Spi 20-855-3 Drop Indicator Thread Conversion Agd

Product Description

The SPI 20-855-3 is a thread conversion accessory designed for use with AGD dial indicators in drop indicator setups. Machined from steel, this compact adapter converts the thread interface to ensure a secure, accurate connection between the indicator and its mounting stem. With a shank diameter of 0.2 inches, it fits standard AGD indicator configurations and is a common component in precision measurement and inspection setups. Machinists, tool and die technicians, and quality control professionals use this type of adapter to maintain indicator alignment and eliminate thread compatibility issues in gaging fixtures.

This thread conversion is suited for precision measurement environments including machine shops, inspection departments, and manufacturing floor applications. It is intended for use with AGD-pattern dial indicators in drop indicator configurations where thread compatibility between the indicator and mounting hardware is required. Its small footprint and steel construction make it appropriate for both bench-top and in-process inspection work.

Key Features

• Steel construction for durability and dimensional stability under repeated use
• 0.2-inch shank diameter fits standard AGD dial indicator mountings
• Converts thread interface for compatible drop indicator setups
• Compact dimensions suitable for tight fixture and gaging applications

Compatibility

Designed for use with AGD dial indicators in drop indicator configurations requiring thread conversion.

Installation Notes

Installation is typically performed by machinists or metrology technicians as part of indicator setup or fixture assembly. Ensure the indicator and mounting stem are free of debris and damage before threading the adapter in place. Hand-tighten to avoid cross-threading or damage to precision threads. Do not use power tools or excessive force when engaging the adapter.
