Starrett 56043 Dial Drop Indicator 0-10-0 Jeweled Bearing

Product Description

The STARRETT 56043 is a metric dial drop indicator designed for precise surface and dimensional measurement in machine tool, inspection, and metrology applications. It features a jeweled bearing mechanism for smooth, repeatable movement and a 0-10-0 bidirectional dial reading with 0.0020 mm graduation. The dial is 1-11/16 inches (42.86 mm) in diameter with a yellow no-glare satin finish face and an unbreakable crystal for durability in shop environments. The stainless steel stem measures 0.38 inches in diameter and 0.875 inches in length, keeping the unit compact and easy to mount in standard indicator holders.

This indicator is suited for use in quality control, machine setup, and fixture work where metric readings are required. The AGD Group 1 classification means it fits standard AGD-compatible indicator stands, magnetic bases, and back-plunger holders commonly found in machine shops and inspection departments. It ships with both a lug back and a flat back, giving installers flexibility for different mounting configurations without additional hardware.

Key Features

• Jeweled bearing for accurate, long-service measurement performance
• 0-10-0 bidirectional dial reading with 0.0020 mm graduation per division
• No-glare satin finish yellow dial for clear readability under shop lighting
• Unbreakable crystal protects dial face from chips and coolant splash
• Stainless steel stem resists corrosion in wet or coolant-present environments
• Includes both lug back and flat back mounting plates for versatile installation

Compatibility

Classified as AGD Group 1, this indicator fits standard AGD-compatible indicator holders, magnetic base arms, and universal back-plunger mounts used across general machining and inspection setups.

Installation Notes

Installation is performed by machinists, toolmakers, and inspection technicians using a standard indicator holder or magnetic base arm. Secure the stem in the holder clamp without overtightening, as excessive clamping force on the stem can affect spindle movement and reading accuracy. Zero the dial after seating the contact point against the reference surface before taking measurements. No electrical isolation or power-down is required for this purely mechanical instrument.
