How to select the correct OSG tap for UNC threads?

To select the correct OSG tap, match the thread size (e.g., 7/16"-14 UNC), thread class (2B), and tap type (spiral point for through-holes). Consider material hardness and hole depth. For oversized taps like the H11 tolerance, ensure the pre-tap hole diameter is adjusted accordingly. Consult OSG's technical data for best results.
