• Diameter 12.28 mm for end-measure checks
• Tolerance ±0.002 mm high precision
• Supplied in protective transport case

Precision where measurement decisions become reliable

This inspection pin offers industrial-grade precision tailored for repeatable checks. With a stated deviation of ±0.002 mm, the component supports tight tolerance verification during in-process inspection and final quality control. The nominal diameter of 12.28 mm is produced to consistent manufacturing tolerances so that fits and clearances can be assessed without additional adjustment. In practical terms, the high resolution of the gauge pin reduces measurement uncertainty and helps to avoid costly rework by providing a stable reference for plug gauges, fixtures and verification jigs. The compact form also minimises thermal drift during short handling periods.

Built for workshop use and straightforward handling

Designed as a workshop version, the pin combines robust construction with compact dimensions that suit routine shop‑floor workflows. The 50 mm length provides sufficient engagement for end‑measure checks while remaining easy to handle and store. Supplied in a protective transport case, the item is protected during transit and ready for secure storage on the bench. The modest mass and balanced geometry simplify use in assembly and inspection stations where fast, repeatable measurements are required and where tools must be changed frequently without specialist fixtures.

Material choice and practical durability

Manufactured from special steel, the gauge pin is chosen for dimensional stability and surface endurance under normal workshop conditions. The material selection supports consistent contact behaviour during short verification tasks and helps to preserve the measuring face from premature wear. The steel specification is translated into a reliable tactile feel when used with reference blocks or alignment sleeves, improving operator confidence during quick verification sequences. Regular visual inspection and correct handling extend service life and maintain performance across multiple cycles.

Application scope and workpiece compatibility

Classified in the micro measurement range (10–100 mm), this inspection pin is particularly suited to fine mechanical work, small components and precision assemblies where compact measuring tools are preferred. Typical uses include end‑measure checks on turned shafts, verification of bores via go/no‑go fixtures, and use as a reference element in custom test rigs. The combination of the workshop design, compact size and tight tolerance makes it an effective tool for both machine shops and quality departments that require straightforward dimensional checks without complex instrumentation.
