Product Description

The SPI Z1020 is a drop indicator probe holder designed to securely position and retain the probe on AGD-style dial indicators with a 4-48 thread size. It serves as an accessory component that keeps the probe assembly aligned during precision measurement tasks. This part is used by machinists, metrology technicians, and quality control professionals who rely on AGD dial indicators for dimensional inspection and surface runout checks. The holder provides a reliable mechanical interface between the indicator body and the probe, supporting consistent, repeatable readings during use.

The Z1020 is suited for shop-floor and toolroom environments where AGD dial indicators are standard equipment. Typical applications include surface plate inspection, lathe and mill setups, fixture alignment, and any measurement task requiring a properly retained probe.

Installation Notes

Installation is typically performed by a machinist or metrology technician. Before replacing or installing the probe holder, ensure the dial indicator is removed from any active measurement setup and is not under load. Use appropriate hand tools sized for the 4-48 thread to avoid cross-threading or damage to the indicator body. Follow the indicator manufacturer's assembly guidance when reattaching probe components.
