Spi SWI1001-38L Test Indicator Clamp Dovetail

Product Description

The SPI SWI1001-38L is a test indicator clamp designed for use with dovetail style dial test indicators. This accessory provides a secure mounting solution that holds the indicator firmly in place during precision measurement work. With an overall length of 3 inches and a shank length of 2 inches, it is a compact, lightweight clamp weighing 0.05 pounds. Machinists, tool and die makers, and quality control technicians rely on this type of clamp when setting up dial test indicators on magnetic bases, surface plates, or machine tool spindles.

This clamp is suited for precision measurement and inspection environments where dial test indicators with a dovetail mounting interface are in use. Typical applications include part alignment on CNC machining centers, manual mills, lathes, and surface grinders, as well as fixture setup and runout inspection in quality assurance workflows. Its compact profile makes it practical in tight setups where clearance is limited.

Installation Notes

This clamp is typically installed by machinists or metrology technicians as part of a dial test indicator setup. Ensure the indicator dovetail interface is clean and free of burrs before seating the clamp. Tighten the clamp fastener to secure the indicator without over-torquing, which can distort the dovetail or affect measurement accuracy. Always zero the indicator after final clamp tightening to confirm no shift occurred during setup.
