Magnetic On/Off Switch Quickly activate or deactivate the magnetic base with a simple switch, enabling smooth repositioning without risking damage to your dial indicator or the workpiece. Alloy Steel Construction Built from durable alloy steel with a chromeplated finish for wear resistance and a rustresistant surface, helping the base maintain functionality and appearance over time. Flexible Positioning Arm Adjustable arm that locks securely at any angle. Antiloose springs and a central locking mechanism provide stable, reliable support for precise technical measurements and mechanical adjustments. Multiple Size Options Three thread configurations are available: M8 x 1.25 with lengths of 300 mm (12 in) and 340 mm (13.6 in), and M5 thread with a length of 165 mm (6.6 in). This range covers different measurement setups and fixtures. Use scenarios Attach to a milling machine or bench to hold a dial indicator for runout checks, with quick repositioning to test multiple points. Use during fixture alignment and calibration tasks where changing angles and positions is needed while preserving accuracy. Set up metrology or inspection work on fixtures or jigs that require different thread fits and reach.
