CTD Type 24-AG Tap, 1/4-28

CTD Type 24-AG Tap, 1/4-28

The 60841 CTD Type 24-AG Tap (1/4"-28) is a precision threading tool designed for cutting internal fine threads in metal and other machinable materials. Manufactured for durability and accuracy, this tap produces 1/4"-28 UNF (Unified National Fine) threads, commonly used in automotive, machinery, and mechanical applications requiring tighter thread engagement. Built for consistent cutting performance, the Type 24-AG design allows efficient chip removal and smooth thread formation when used with proper cutting lubricant. It’s an essential shop tool for creating or restoring fine threads—because sometimes the only way forward is cutting the threads yourself.
