1. High PrecisionThe telescopic gauge set features double action handles that are rigidly attached to the plungers, ensuring stability and precision. The handles are also self centering, making measurements easier and more accurate 2. Versatile ApplicationThis gauge set is designed to assist in quickly checking holes, slots, and recesses up to 6 inches deep. It is suitable for a wide range of industries and applications, providing convenience and efficiency in measuring tasks 3. Precision MachinedThe ends of both plungers are made of heat treated steel and precision ground to a radius. This design allows for proper clearance on the smallest holes that the gauge will enter, ensuring accurate measurements every time 4. Uniform PressureWith constant spring tension, this telescopic gauge set delivers uniform pressure, eliminating the risk of inconsistent measurements. It ensures consistent results no matter the application
