To select the correct OSG spiral point tap for UNF threads, match the thread size (e.g., 3/8"-24 UNF) and tolerance class (e.g., 2B+ for tighter fits). Consider material type and hole depth—spiral point taps suit through-holes. For oversized threads, use taps marked as oversized, like the OSG 1591800, to achieve precise thread class.
