Select an OSG tap by matching the thread size (e.g., 5/8"-18 UNF) and tolerance class (e.g., 2B+) to your application. For through holes, use a plug chamfer; for blind holes, use a bottoming chamfer. High-speed steel taps suit general-purpose threading in steel. Always verify the material and thread depth before ordering.
