Gauge pin M323.691 — gauge pin with 6.91 mm diameter and ±0.001 mm tolerance (Metav IndustryLine)

The gauge pin M323.691 is a single, high‑precision inspection pin designed for end‑measurement and verification tasks in workshop metrology.

• Diameter 6.91 mm, tolerance ±0.001 mm
• Length 50 mm for compact measuring setups
• Workshop‑grade design for robust daily use
• Made from high‑grade special steel

Ensure production accuracy with sub‑micrometre repeatability

A measuring element with a tolerance of ±0.001 mm provides the kind of repeatable result required where tight fits and narrow clearances determine assembly quality. The small diameter of 6.91 mm and the 50 mm length mean the component is easy to position in fixturing and measuring jigs, reducing setup time and cumulative error. The form stability of a precision gauge pin converts dimensional capability into traceable results, supporting consistent in‑process verification and quality assurance workflows.

Workshop durability and material choice that supports reliability

Constructed from special steel, this inspection pin balances hardness with corrosion resistance appropriate for everyday use in a workshop environment. The workshop version specification indicates components and finishing chosen to withstand handling, while still preserving measuring faces necessary for accurate readings. The material choice limits wear during repeated insertion and extraction cycles, so calibration intervals are extended and maintenance effort is reduced, which benefits throughput and uptime in small to medium‑sized production settings.

Practical use: where the measuring pin improves process control

As a single inspection element, the measuring pin is intended for plug and end‑face checks, go/no‑go verification in gauge blocks or nest fixtures, and spot checks during assembly. The compact geometry permits access to confined bores and recesses where larger gauges are impractical. When combined with systematic measurement routines, the pin helps to reduce scrap and rework by catching deviations at early stages; its simple form also makes it straightforward to clean, store and integrate into existing control plans without special adapters.

FAQ

What measuring tasks is this pin suitable for?
The gauge pin M323.691 is designed for end‑measurement, plug checks and spot dimensional verification in workshop metrology, especially where a compact 50 mm length and 6.91 mm diameter are required.

How precise is the inspection pin and what does the tolerance mean?
The inspection pin carries a tolerance of ±0.001 mm, which represents the manufacturing and calibration allowance; this level of precision supports tight‑fit checks and repeatable go/no‑go assessments.

What material is used and how does that affect longevity?
Made from special steel, the M323.691 offers a balance of hardness and corrosion resistance that prolongs service life under routine handling and reduces wear on the measuring faces.

Is the pin intended for heavy industrial use or workshop inspection?
The specification as a workshop‑grade inspection pin indicates it is optimised for daily workshop and production‑line use rather than extreme heavy‑duty applications.
