Built for Longevity & Accuracy
Every gauge is manufactured under a proven quality control system, ensuring long-term dimensional stability and consistent performance.
Standards-Compliant Manufacturing
Pin gauges are made in accordance with BS969:1982, using component hole tolerancing as the basis for gauge manufacturing tolerances.
Practical & Easy to Use
Each gauge pin is 50mm in length and mounted in a durable black hexagonal handle, clearly marked with the Go and No Go dimensions. For quick identification, handles are colour-coded — green for Go and red for No Go.
