Taptite®

The Taptite® family of thread rolling screws form threads in plain cored, drilled or punched holes upon assembly, creating vibration resistant assemblies. This eliminates the need to pre-tap internal threads in ductile materials such as steel, aluminium and zinc. It also makes it unnecessary to add safe elements such as toothed washers and self-locking nuts – thus lowering the cost of assembly.

Taptite® II Trilobular thread-rolling screws roll-form strong, high integrity threads in drilled, punched or cored holes in ductile metals and castings. As each lobe of the screw moves through the pilot hole in the nut material, it forms and work-hardens the nut thread metal producing an uninterrupted grain flow. By elastic recovery, metal fills in behind the lobe, providing a greater area of thread contact with exceptional vibration resistance and fastening strength.

Prior to Taptite® fastening of thick metal pieces was achieved through either a nut and bolt joint or a tapped hole and bolt joint.

Taptite® II will never cross thread at assembly as their primary purpose is to form threads as they are driven into non-threaded nut members. This reduces the “in-place cost” of the joint and the cost of pre-tapping.
