Self-Locking Taps Eliminate Assembly Procedures

The self-locking tap design eliminates time intensive disassembly and assembly procedures and costly fasteners, chemical bonds, nylon plugs or other devices to maintain tightness.

Dormer Pramet’s Union Butterfield brand of self-locking taps are a self-locking thread form that can be produced on a straight flute, spiral flute spiral point, roll form and on the company’s line of high performance taps.

The self-locking tap design eliminates time intensive disassembly and assembly procedures and costly fasteners, chemical bonds, nylon plugs or other devices to maintain tightness. In short, the company’s taps provide efficiency in operation and cost.

A 30-degree wedge lock on the female thread creates a continuous spiral contact along the entire thread length for improved holding power versus standard thread forms.

Working with aluminum or other lightweight, soft materials? The optimum load distribution provided by Union Butterfield’s self-locking thread form eliminates thread stripping that is typical when clamping load is concentrated on fewer threads. Clamp load forces with the Union Butterfield self-locking thread design are spread evenly across all threads as compared with a conventional 60-degree thread form that puts clamping force only on the first few threads with the other threads receiving limited or no contact at all.
