Gauge pin, single — 12.75 mm Ø, 50 mm length (Metav IndustryLine)

Gauge pin, single — 12.75 mm Ø, 50 mm length is a workshop-grade inspection pin for dimensional checks and assembly gauges, designed for routine use in production and quality-control work.

• Workshop-grade construction
• Nominal diameter 12.75 mm
• Tolerance ±0.002 mm
• 50 mm overall length

Durable accuracy for everyday inspection tasks

The compact inspection pin offers consistent dimensional stability, with a nominal diameter of 12.75 mm and a verified tolerance of ±0.002 mm that supports tight fit and clearance testing. The tight tolerance reduces rework by providing a repeatable reference for bore inspection, alignment fixtures and final assembly checks. Because the diameter is specified to three significant figures, it simplifies interchangeability and reduces the need for on-the-spot adjustments during batch inspections.

Designed for precise fit and functional testing

As a single-piece gauge pin, this item is ideal for plug checks, spacer-setting and functional go/no‑go trials where a reliable reference diameter is required. The 50 mm length gives sufficient engagement for small-to-medium bores while remaining easy to handle and store. The clear nominal dimension and low runout tendency make the pin suitable for checking mating parts, verifying hole reaming and confirming seating positions in jigs and fixtures.

Robust material and surface finish reduce wear

Manufactured from special steel, the pin resists deformation and abrasive wear under normal workshop conditions, extending service life and maintaining metrological integrity. A carefully finished surface minimises friction and prevents scoring in precision bores, reducing the risk of false rejections. The workshop specification balances hardness and toughness so that the pin sustains repeated contact without compromising the specified ±0.002 mm accuracy.

Simple identification and stock integration

Marked with the internal SKU and accompanied by a GTIN, the gauge pin integrates easily into inventory systems and calibration schedules. The compact geometry keeps handling straightforward and the lightweight construction (approx. 0.1 kg) simplifies storage and transport within production areas. For customers consolidating suppliers, the Metav IndustryLine range provides a dependable option that aligns with common metrology workflows and procurement routines.
