How to select the correct OSG tap for a threading application?

To select the correct OSG tap, match the thread size and pitch (e.g., 3/8-24 UNF) to your hole specifications. Choose the chamfer type (plug for through-holes) and tolerance class (H4 for 2B-3B fit). Consider material and coating; high-speed steel works for general-purpose threading. Consult OSG's technical data for optimal performance.
