M304.609 micrometer screw gauge — ratchet, matt‑chromed thimble

M304.609 is a compact, analogue micrometer screw gauge designed for precise external measurements in fine mechanical and workshop environments

• Ratchet stop for consistent measuring force
• Matt‑chromed thimble for clear scale reading
• 25–50 mm range for fine mechanical work

Reliable construction for consistent readings

The instrument features a painted frame and a matt‑chromed measuring thimble, chosen to reduce glare and wear over repeated use. The mechanical design follows DIN 863, providing a familiar standard for quality and interchangeability in industrial environments. With an analogue graduation of 0.01 mm, the screw gauge gives a clear, decimal‑based reading that is easy to interpret on the thimble. The result is a tool that supports routine shop floor inspection and set‑up tasks with predictable performance.

Controlled feed and fine adjustment for delicate parts

A 0.5 mm spindle pitch and a spindle diameter of 6.5 mm ensure steady axial movement and low play during adjustment. The integrated ratchet stop prevents over‑tightening and standardises the contact pressure, which reduces user‑introduced variance when measuring small components. For tasks where repeatability matters, the mechanical interplay of pitch, thimble graduation and ratchet yields reliable single‑turn increments and accurate hundredths‑of‑a‑millimetre readings.

Compact range tailored to precision components

The 25–50 mm measuring span places this gauge in the compact class for detailed mechanical work: ideal for small shafts, bearing journals and components in precision assemblies. Built to serve routine workshop inspection and quality control, the instrument balances reach and stiffness, making one‑handed operation straightforward without sacrificing measurement stability. The device is part of the Metav IndustryLine offering, which emphasises consistent manufacturing checks and dependable delivery for professional users.
