Test pin (single) – 12.9 mm diameter, 50 mm length by Metav IndustryLine

Test pin for precise end-dimension inspection and workshop gauging applications

• Precision diameter 12.9 mm
• 50 mm hardened length for stable support
• Accuracy ±0.002 mm
• Special steel workshop design

Repeatable results for small components

The compact gauge is engineered for consistent inspection of end dimensions where tight tolerances matter. With a 12.9 mm measuring diameter and a declared ±0.002 mm deviation, the pin functions as a reliable reference in production controls and receiving inspections. The small form factor suits tasks that require repeatability rather than long reach, reducing error sources from handling and ensuring that each measurement contributes to verifiable quality documentation.

Robust design for everyday workshop use

Built as a workshop version, the component combines wear resistance and handling strength. The special steel composition provides improved surface hardness and resistance to frequent seating and removal, which reduces downtime for replacements. For machinists and quality technicians this translates into a lower total cost of ownership: fewer replacements and consistent contact geometry for quicker, more dependable checks during batch processing.

Stable handling and measurement stability

A 50 mm shank length offers a balance between usability and support: long enough for a secure grip in fixtures, yet short enough to keep bending and vibration to a minimum during tactile or fixture-mounted checks. The geometry promotes stable seating in gauges and ensures the contact surface remains perpendicular to the inspection plane, helping technicians achieve consistent results with minimal setup time.

Ideal for micro‑range metrology tasks

Classified in the micro range (measuring range up to 100 mm), this inspection element is aimed at fine mechanical work such as small assemblies, fixtures and precision components. Its compact footprint and precision rating make it suitable as a workshop standard for routine end‑dimension verification where space and handling convenience matter more than extended reach.

FAQ

What is the declared tolerance of this inspection pin?
The Test pin from Metav IndustryLine (M323.C90) is specified with an accuracy of ±0.002 mm, allowing for very fine end-dimension checks in workshop environments.

Is the test pin suitable for fixture-mounted gauges?
Yes. The 50 mm length and stable shank geometry make the Metav IndustryLine test pin appropriate for use in fixture-mounted or handheld gauge assemblies where a rigid reference is required.

Which materials is the pin made from and what does that mean for wear?
The test pin is manufactured from special steel, chosen for improved surface hardness and wear resistance, which extends service life under frequent seating and removal cycles.

Can this pin be used for large-scale measurements?
This component is designed for the micro range (measuring range up to 100 mm) and is optimised for small to medium components; it is not intended for long-reach measurements where larger gauges or alternative systems are preferable.

How does the workshop version differ from lab-grade pins?
The workshop execution emphasises robustness and practical handling for daily shop use; while it maintains high precision, the design prioritises durability and ease of use over features found in delicate laboratory instruments.
