Gauge pin M323.857 — single gauge pin, Ø 8.57 mm, ±0.001 mm, 50 mm (Metav IndustryLine)

A gauge pin M323.857 designed as a workshop‑grade test pin for high‑precision end‑measurements, component inspection and go/no‑go verification in production and maintenance environments

• Tolerance ±0.001 mm
• Diameter Ø 8.57 mm precision
• 50 mm length for confined measurements
• Special steel; workshop version

Precision that suits production control

This workshop‑grade test pin delivers an exceptionally fine tolerance of ±0.001 mm, which corresponds to one micron accuracy and supports tight quality tolerances in small‑part production. The Ø 8.57 mm diameter is turned and ground for a high‑quality surface finish, reducing measurement uncertainty when used as a reference mandrel or plug for bore checks. Such dimensional stability makes the pin suitable for repeatable end‑measurement tasks and helps maintain consistent inspection results across production batches.

Practical design for everyday inspection tasks

With a 50 mm length, the pin is compact enough to reach confined bores and to be handled comfortably during manual inspection sequences. The special steel material provides a balance of hardness and wear resistance suitable for workshop use, while the workshop specification ensures robustness under routine handling. Delivered in a transport case for secure movement between toolroom and shop floor, this test pin supports efficient measurement workflows without adding unnecessary handling risk.

Clear benefit for quality assurance and assembly

Using this single gauge pin simplifies go/no‑go checks and alignment operations, reducing inspection time and lowering the risk of assembly errors. The part functions as a stable reference for end‑dimension control, allowing technicians to verify mating fits and ensure conformity to specified end measurements. Where traceability and repeatability matter, the pin contributes to fewer rejects and a smoother production flow by providing a deterministic reference dimension for quick inspections
