Dormer Pramet says that its Union Butterfield self-locking taps offer efficiency in operation and cost. The taps are designed to improve holding power, eliminating time-intensive disassembly and assembly procedures as well as costly fasteners, chemical bonds, nylon plugs or other devices used to maintain tightness. A 30-degree wedge lock on the female thread creates a continuous spiral contact along the entire thread length for improved holding power.

The taps are said to eliminate the thread stripping that can occur when clamping load is concentrated on fewer threads, enabling clamp load forces to spread evenly across all threads. They are suitable for transportation, medical or industrial use. The self-locking thread form can be produced on straight flute, spiral flute, spiral point, roll form and the Union Butterfield line of high-performance taps.
