CNC Thread Depth & Fit Visualizer

Enter the thread diameter and pitch. See exactly how deep to machine the thread and what dimensions the mating bolt or nut requires.

Enter measurements for both mating parts. Pitch diameters govern the fit; without both pitch diameters the result is an estimate, not a certified tolerance inspection.

EXTERNAL · CUSTOM

Deterministic engineering geometry for custom diameters and pitches. Validate against the relevant thread standard and the machine’s limits before cutting.

Machine your nut

INTERNAL · ISO 6H

Nominal size identifies the thread. Manufacturing acceptance is determined separately from ISO metric tolerance limits, principally at pitch diameter. Confirm with calibrated thread gauges and the applicable controlled standard before release.
