Spi SWI1001-8MM Test Indicator Clamp Dovetail Pin

Product Description

The SPI SWI1001-8MM is a dovetail pin-style clamp designed to secure dovetail style dial test indicators during precision measurement work. Finished in black oxide for corrosion resistance, this clamp provides a stable, repeatable connection between the indicator and its mounting point. The overall length is 1.5 inches, with a shank length of 18 millimeters. It is a single-piece accessory intended for use by machinists, toolmakers, and metrology technicians who require consistent, low-runout indicator placement on surface plates, magnetic bases, and indicator holders.

This clamp is used in machine shop, inspection, and quality control environments where dovetail style dial test indicators are mounted for part inspection, runout checks, and surface comparisons. It is suited to both production floor and lab settings. The black oxide finish keeps the part visually neutral and reduces light reflection during close inspection work. Packaged as a single unit, it is a straightforward replacement or spare for existing indicator setups.

Installation Notes

Installation is performed by machinists or metrology technicians. Before mounting or removing the clamp, ensure the indicator and any associated magnetic base or holder are fully de-energized or released. Secure the shank into the holder to the appropriate depth before tightening to avoid lateral play. Do not overtighten, as this can damage the dovetail interface on the indicator.
