Screw Gauge – Precision Instrument for Micrometric Measurement | Manufactured by Samtech Instruments

Samtech Instruments, a trusted manufacturer of scientific lab instruments since 2002, offers a high-quality Screw Gauge—an essential measuring tool designed for precise micrometric measurements in school and college physics labs.

Used widely in mechanics, materials science, and engineering labs, this device helps students and technicians measure small dimensions like wire diameter, sheet thickness, and more with superior accuracy.

What Is a Screw Gauge?

A Screw Gauge, also known as a micrometer screw, is a precision instrument that measures extremely small lengths—typically in the range of 0.01 mm. It uses the principle of a screw thread to convert small linear distances into measurable rotations.

The device consists of a screw spindle, thimble, sleeve (main scale), ratchet, and anvil. As the screw rotates, the object to be measured is clamped between the anvil and the spindle, and the measurement is read from the scales.

The Screw Gauge Typically Includes:

• Stainless steel or alloy frame and spindle
• Clearly marked main and circular scales
• Smooth-turning ratchet mechanism
• Locking screw for measurement hold
• Measuring range: typically 0–25 mm, least count: 0.01 mm
