Gauge pin M323.452 — 4.52 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

The Gauge pin M323.452 is a single, workshop‑grade test pin designed for precise end‑dimension checks and fit verification in inspection and assembly workflows.

• Diameter 4.52 mm for precise fits
• Tolerance ±0.001 mm for submicron control
• 50 mm hardened test pin length
• Workshop‑grade special steel construction

Precision that reduces rework and inspection time

Manufactured to a tight ±0.001 mm tolerance on a 4.52 mm nominal diameter, this test pin provides the dimensional certainty required in fine inspection tasks. The very small tolerance reduces measurement uncertainty and supports consistent pass/fail decisions at the control station, minimising rework and downtime. For users unfamiliar with tolerance levels: ±0.001 mm denotes a variation of one micrometre, which is comparable to the thickness of a fine human hair and is suitable where high repeatability is essential.

Durable design for everyday workshop use

Built as a workshop‑grade component from special steel, the pin balances hardness and toughness to withstand repeated insertion and extraction in jigs, bushings and mating bores. The 50 mm overall length provides ample engagement depth for stable reference contact without excessive overhang, while the low mass supports quick handling and alignment during routine checks. These material and dimensional choices translate directly into longer life, fewer replacements and predictable behaviour under mechanical stress.

Practical handling and application scenarios

Supplied as a single test pin for direct use in verification tasks, this gauge pin is ideal for end‑dimension checks, assembly go/no‑go fixtures and finish‑control operations where precise fit is critical. The compact diameter and hardened surface make it suitable for confirming bore sizes, verifying plug fits and establishing reference points during final inspection. The part is particularly useful where accurate end‑measurements ("end dimensions") determine final acceptance further down the production line.
