The Laboratory Screw Gauge is a reliable precision measuring instrument designed for determining the thickness, diameter, and dimensions of small objects with high accuracy. Manufactured using durable metal materials, this instrument features a sturdy U-shaped frame, a calibrated sleeve, a rotating thimble, and a precision screw mechanism that allows controlled measurement of small dimensions. Its practical design makes it suitable for measuring thin wires, metal sheets, small cylindrical objects, and other laboratory specimens. The screw gauge is widely used in physics laboratories, engineering colleges, educational institutions, research centers, and industrial testing facilities for conducting dimensional measurements and scientific experiments. With its robust construction, easy-to-read scale, smooth adjustment mechanism, and precise measuring capabilities, the Laboratory Screw Gauge is an essential instrument for educational, scientific, and engineering applications.
