Gauge pin M323.687 — 6.87 mm ±0.001 mm, 50 mm length (Metav IndustryLine)

A precision Gauge pin M323.687 intended for dimensional checks and reference measurements in workshop and inspection environments

• High-precision diameter 6.87 mm ±0.001 mm
• Hardened special steel construction
• Length 50 mm for stable reference measurements
• Delivered in protective case for transport

Reliable tolerance control for consistent inspection results

The core advantage of this checking pin is its ±0.001 mm tolerance, which supports tight dimensional control in repetitive inspection processes. Such high accuracy reduces measurement uncertainty during go/no-go and reference checks, ensuring components conform to drawing tolerances. The small form factor and consistent diameter make the pin suitable as a reference gauge in fixture set-ups and bench inspections, where repeatability and traceable sizes matter. The precision specification is particularly beneficial when replacing worn pins in modular gauges or when confirming final bore sizes during assembly.

Robust material and workshop design for everyday use

Manufactured from special steel and offered as a workshop version, the pin balances wear resistance with practical handling. The material choice provides surface hardness and dimensional stability under regular use, while the compact 50 mm length keeps the tool rigid for short-span measurements. The workshop styling prioritises durability and straightforward insertion and extraction from bores or fixture housings. This combination lowers lifecycle costs by extending service intervals and reducing the need for frequent replacements.

Practical application in quality control and assembly

As a dedicated reference element, the pin performs well in batch inspection, fixture set-up and tolerance verification tasks. Use of a standardised diameter such as 6.87 mm simplifies inventory and reduces set-up time when swapping between similar gauges or modular fixtures. The component integrates readily into manual and semi-automated processes, serving as a tactile standard for quick pass/fail checks or for establishing datum points in small assemblies. Its compact dimensions make it suitable for confined measuring positions where larger gauges would be impractical.

Protected delivery and handling facilitate safe storage

Delivery in a protective case mitigates transport damage and preserves the pin’s calibre right up to point-of-use. The case supports organised storage, keeps reference surfaces free from contamination, and helps maintain the specified tolerance through reduced handling wear. For workshops that require simple logistical handling, the packaged format eases stock management and ensures that the tool is inspection-ready immediately upon retrieval from inventory.
