Description
Thread Gauge Go 7/16-20 UNF (64-823040)
This precision-engineered Go thread gauge with a dimension of 7/16-20 UNF is an essential tool for quality control and inspection of external threads. The gauge is used to verify that threads meet the specified tolerance requirements according to the UNF standard (Unified National Fine). With its ”Go” function, it confirms that thread dimensions do not exceed the upper tolerance limit, ensuring correct fit and function in the final application.
Manufactured with utmost precision, this thread gauge provides accurate measurement results for 7/16-inch threads with 20 threads per inch according to the UNF specification. The gauge’s hard and wear-resistant construction guarantees long-term accuracy and reliability, even with frequent use in industrial environments. Each gauge is manufactured according to strict quality standards and is delivered with traceability documentation confirming its accuracy.
