• Accuracy ±3.5 µm
• Thermal protection sleeve
• 8 mm shaft diameter

Precise reference that keeps production consistent

A solid reference standard reduces set‑up time and rejects. The robust 250 mm body is specified for use as a setting gauge for external micrometers and provides a clear, measurable baseline for size control. With an accuracy of ±3.5 µm, the device allows tighter control limits compared with routine workshop standards, enabling faster decisions on tool offsets and process corrections. The measurable advantage is fewer reworks and more predictable throughput because measurements used for adjustment are reproducible and traceable.

Design that minimises thermal influence and handling error

Thermal drift is a common source of short‑term measurement variation. The integrated thermal protection decreases the effect of hand warmth during frequent comparisons and helps maintain the reference temperature of the setting surface. Flat measuring faces give a stable contact geometry, while the slender 8 mm shaft and compact mass (approx. 0.3 kg) simplify positioning without introducing excessive cantilever forces. Together, these features reduce user‑induced variance and make routine setting tasks quicker and more consistent.

Practical benefits for workshop calibration and set‑ups

The unit is tailored for frequent use in manufacturing and quality control: it acts as a simple, portable master when calibrating or checking screw‑type micrometers and speeds up inspection workflows. The flat contact surfaces and compact form factor support reproducible placement on micrometer anvils, so fewer comparisons are needed to confirm correctness. This directness translates into time saved at every set‑up and increased confidence in first‑piece approvals and in‑process checks.

FAQ

What is the primary use of this setting gauge?
The micrometer setting gauge M304.318 is intended as a reference for setting and checking external micrometers, ensuring reproducible contact and dimension transfer during workshop set‑ups.

How accurate is the device for precision checks?
The setting gauge offers an accuracy of ±3.5 µm, making it suitable for tighter tolerance verification and repeatable setting procedures in industrial environments.

Does the gauge require special handling to maintain accuracy?
Normal care applies: avoid prolonged hand contact before measurement to reduce thermal influence; the built‑in thermal protection helps but stable handling and clean flat faces ensure best results.

Can this gauge be used at the inspection bench and on the shop floor?
Yes — the design balances portability and stability so the unit serves both inspection benches and on‑machine or shop‑floor set‑ups where rapid, repeatable comparisons are needed.

Which product code should be referenced when ordering or requesting data sheets?
Refer to SKU M304.318 and the Metav IndustryLine designation for all technical inquiries and ordering.
