Gauge pin M323.686 — Precision test pin, 6.86 mm ±0.001 mm (Metav IndustryLine)

M323.686 gauge pin is a single-piece precision test pin intended for end-dimension checks and inspection tasks in machine shops and quality control.

High-precision ±0.001 mm tolerance
Special steel with workshop finish
50 mm length for steady handling
Delivered in a protective transport case

Assured dimensional control for inspection and production

The test pin delivers a ±0.001 mm tolerance on a 6.86 mm diameter, providing a measurable improvement in go/no-go evaluation and ending corrective rework cycles. As a hardened measuring pin, it functions as a fixed reference for bore and end-mass checks, enabling clear go/no-go decisions and rapid recording of conformity. The defined tolerance reduces uncertainty in inspection, supporting tighter process control and consistent production outputs.

Durable construction that simplifies daily handling

Manufactured from special steel and supplied in a workshop version, the pin resists wear on contact surfaces and maintains dimensional stability under routine use. The 50 mm length gives a favourable ratio of reach to rigidity, making single-handed handling straightforward while reducing the risk of bending during measurement. Supplied in a protective transport case, the component arrives ready for use and protected in transit, helping to preserve calibration and surface integrity.

Practical applications and traceable measurement routines

This precision pin suits metrology benches, fixture set-ups and end-of-line checks where repeatable reference dimensions are required. Its compact form is ideal for bench inspection and assembly jigs, while the robust finish supports everyday shop use. The low mass (approx. 0.018 kg) and compact geometry make the item easy to store and position within fixtures, contributing to fast, reproducible checking routines and less handling time between measurements.
