AT Hand Taps

AT hand taps are threading tools used to cut internal threads in a drilled hole using a tap wrench or hand tapping setup (application dependent). They’re commonly used in maintenance, repair, and fabrication work for creating new threads, restoring damaged threads, or producing threaded holes when a machine tap isn’t practical. Choosing the right hand tap starts with matching the thread standard (SAE/UNC/UNF or metric), the size and pitch, and the tap style that fits your hole depth and threading needs.
