M323.325 gauge pin — high‑precision 3.25 mm test pin (Workshop version)

The M323.325 is a single gauge pin designed for precise end‑measure inspection and go/no‑go verification in workshop and production environments.

• Workshop version, robust design
• Diameter 3.25 mm for tight fits
• Tolerance ±0.001 mm high precision
• Length 50 mm for end‑measure checks

Micron‑level accuracy for consistent quality

This gauge pin delivers ±0.001 mm tolerance, corresponding to a one‑micrometre band of deviation that significantly reduces uncertainty in short‑range measurements. Such high precision is especially valuable when validating end dimensions, comparing mating parts or setting reference gauges. The narrow 3.25 mm diameter provides reliable contact in small bores and passages, while the 50 mm length is long enough for end‑measure checks yet compact for bench handling. Clear numeric specifications enable easy comparison with inspection requirements and support repeatable quality control.

Durable construction for daily workshop use

Manufactured from Special steel, the pin combines surface wear resistance with the stiffness required for repeat contact. The workshop version designation signals design choices that favour robustness and straightforward handling under frequent use. Low mass and compact geometry assist quick placement and removal from fixtures, reducing cycle times at inspection stations. The result is a hard‑wearing inspection tool that maintains its dimensional stability over many contact cycles, lowering rework rates and machine downtime.

Practical integration into inspection workflows

This test pin functions as an end‑measure reference and can be used in simple go/no‑go assemblies, fixture checks and spot inspections on the shop floor. Its precise diameter and tolerance make it suitable for verifying drilled bores, alignment pins and mating features during setup and first‑piece inspections. Because the specification is unambiguous—diameter, length and tolerance clearly stated—planning for gauge stacks, replacement inventory or QC documentation is straightforward and reduces procurement ambiguity.

Designed to support reliable production decisions

Beyond its technical data, the pin offers a pragmatic benefit: fast, measurable decision points in routine inspections. The compact format suits both standalone bench use and incorporation into modular test fixtures. Where production tolerances are tight, such a precisely defined inspection pin helps to establish a consistent, measurable standard that operators and engineers can trust when assessing part conformity or process drift.
