Precision. Expertise. Customization.

At Precisium, we specialize in manufacturing custom-made thread gauges that meet even the most demanding industrial requirements. From non-standard dimensions to specialized coatings and multi-start threads, we provide tailor-made solutions for specialized inspections and automated processes.

Multi-Start & Asymmetric Threads

Precision thread gauges for non-standard profiles and multi-start configurations.

  • Double, triple, and quadruple lead threads (2–4 starts)
  • High-precision multi-start thread gauges, e.g., M12.5 x 6 P 0.75 – 6g (8-starts)
  • GO/NOT GO plug and ring gauges for multi-start special threads
  • Custom asymmetric thread gauges for unconventional or flat thread profiles
  • Thread ring gauges designed for improved centering using lightly tapered threads

Extended & Reinforced Plug Gauges

Built for depth, tight spaces, and complex inspections.

  • Extended-length thread plug gauges for deep internal threads
  • Plug gauges with increased stem diameters for stability in small, deep-seated threads
  • Tapered GO/NOT GO plug gauges for thread quality and coaxiality inspection
  • Multi-diameter assessment gauges checking thread and up to three concentric diameters
  • Gauges featuring minimum engagement length indicators

Coated Gauges for Durability & Automation

Optimized for long-term use and integration into automated systems.

  • HSS plug gauges with TiCN coating for enhanced wear resistance
  • Dirt collection grooves for clean automated inspections
  • GO thread ring gauges with DLC coating for superior durability
  • Gauges built for repetitive use in automated quality control

Bore & Concentricity Inspection

Ensure precise internal dimensions and thread alignment.

  • Bore gauges to measure minimum bore diameter
  • Concentricity gauges to check thread alignment with the bore
  • Combination thread plug gauges for evaluating coaxiality and engagement

Thread Ring Gauges for Machine Mounting

Specialized for use in inspection systems and machinery.

  • Thread ring gauges with radial and axial run-out checking capability
  • Lightly tapered designs for smooth centering during machine operation
  • Designed for mounting in automated or manual inspection machines

3D Measurement Integration (CMM Tools)

Tools made for modern digital inspection environments.

  • Coordinate gauge rods designed for 3D measuring machines
  • Tapered threads for precise centric mounting and reliable measurements
  • Ideal for determining internal thread positions in digital workflows

Oversized & Non-Standard Thread Gauges

No dimension is too large or complex.

  • Thread gauges up to M280 or 10 inches produced to your exact specs
  • Custom geometries, thread forms, and tolerances available
  • Full traceability and testing for industrial-grade performance
