Thread Gauges

Thread gauges (thread pitch gauges) are identification tools used to determine thread form and pitch on screws, nuts, and threaded holes. They enable quick verification before machining, assembly, or selecting compatible fasteners.

Available in metric and inch standards (e.g., UNC/UNF, BSW/BSF) as well as pipe threads (BSP/NPT), typically as folding sets with hardened steel leaves and clear markings. Options from Insize & Preisser support reliable shop-floor thread identification.

Well suited for machine shops, maintenance, and QC tasks where correct thread matching helps prevent cross-threading and rework.
