This is the ideal all-purpose set!
The T-tap wrenches allow tapping in tight places where handle-tap wrenches don't have the clearance. The die stock has an adjustable cam plate which guides the die for clean straight threading.
Taps, hex dies and screw extractors are made from super duty carbon steel, machined, hardened and tempered to assure clean, consistent, accurate threads.
4-40 through 12-24 (5/8'' hexagon dies)
