Dasqua Thread Wires

Dasqua Thread Wires — 3-Wire Thread Measurement Set

Achieve precise thread pitch diameter measurements with the Dasqua Thread Wires set. Designed for use with a micrometer, these hardened and ground wires are the industry-standard method for accurately measuring the pitch diameter of external threads — far more reliable than optical comparators or thread gauges alone.

How It Works

Three wires of equal diameter are placed in the thread grooves — two on one side, one on the other — and a micrometer reading is taken over the wires. Using the standard 3-wire formula, the exact pitch diameter can be calculated to tight tolerances, making this method essential for precision thread inspection in toolmaking, machining, and metrology.

Key Features
