Standard Hand Taps - Special Thread

Special Thread Hand Taps are designed for applications where standard coarse, fine, or extra-fine thread taps are not applicable or where design considerations require non-standard pitches. Most sizes are available in taper, bottoming, or plug chamfer.

Eight Pitch Hand Taps are classified as coarse pitch series taps. They were originally designed for threading large diameter, high pressure joint bolts and nuts and are now used mainly by oil related industries, utilities, and general construction.

Ten Pitch Hand Taps (Sucker Rod Hand Taps) were designed for use by oil pumping stations to thread sucker rod and other applications requiring quick assembly. 

When taper or bottoming chamfer taps are not available in size ordered, plug chamfer taps will be substituted to complete order.
