Starrett 52886 Drop Indicator Universal Snug 0.375 Inch Stem

Product Description

The STARRETT 52886 is a universal snug accessory designed for use with AGD-style drop indicators that have 0.375-inch stems. A snug is a small clamping collar that mounts onto the indicator stem, allowing the indicator to be positioned and held securely in a magnetic base, comparator stand, or other holding fixture. The 52886 provides a reliable friction fit that prevents unwanted movement during measurement. At 0.125 pounds, it is a lightweight add-on that machinists, quality control technicians, and toolroom professionals add to their indicator setups when the standard stem diameter requires a snug for proper retention.

This snug is used wherever AGD-style drop indicators are deployed in precision measurement applications. Common scenarios include surface plate inspection, fixture gauging, and machine tool setup where an indicator must be held at a fixed height or angle. It is appropriate for both shop-floor and metrology lab environments. Any setup requiring consistent, repeatable indicator positioning on a 0.375-inch stem benefits from this accessory.

Installation Notes

Installation is performed by the machinist or metrology technician setting up the indicator assembly. Slide the snug onto the indicator stem before securing it in the holder or magnetic base. Ensure the snug is fully seated on the stem and tightened according to the holding fixture's clamping mechanism before taking measurements. Do not overtighten, as this can distort the stem or affect indicator accuracy.
