Trapezoidal Thread Gauges are precision instruments used to inspect power transmission screw threads such as those found in lead screws, spindles, and machine tools. These gauges are designed to check the accuracy, pitch, and profile of trapezoidal threads, which are commonly used for converting rotary motion into linear motion under heavy load conditions.
Key Features:
Manufactured as per ISO 2904, DIN 103, and BS 161 standards
Available in GO and NO-GO combinations for both internal and external thread inspection
Offered as Trapezoidal Thread Plug Gauges, Ring Gauges, and Snap Gauges
Thread forms include Tr 8×1.5 to Tr 200×12 or custom sizes on request
Made from hardened tool steel and stabilized for dimensional accuracy
Precision ground and lapped for accurate thread angle (30° included angle)
Supplied with NABL traceable calibration certificates
Technical Specifications:
Hardness: 58–62 HRC
Accuracy: ±0.002 mm
Pitch range: 1 mm to 12 mm
Applications:
Used in automotive, machinery, aerospace, and precision engineering industries
Essential for lead screw, machine tool, and actuator manufacturing
Benefits:Ensures precise thread geometry, reduces operational friction, enhances load-bearing efficiency, and guarantees compliance with global trapezoidal thread standards for maximum reliability.
