Product details
Trapezoidal thread gauges are precision tools used to check the dimensions and tolerances of trapezoidal screw threads. These threads are commonly used in power transmission applications such as lead screws in lathes, jacks, and presses due to their strength and efficiency. Key Features of Trapezoidal Thread Gauges: Thread Profile: The trapezoidal thread has a 30° included angle (15° on each flank). It's named for its trapezoid-shaped thread profile. Types of Trapezoidal Thread Gauges: GO and NO-GO Plug Gauges: For internal threads (female). GO and NO-GO Ring Gauges: For external threads (male). Thread Calipers/Micrometers: For measuring pitch diameter. Pitch Gauges: To verify the thread pitch quickly (less common for trapezoidal). Standard Designations: Threads are denoted as Tr x P, e.g., Tr20x4 where: Tr = Trapezoidal thread 20 = Nominal diameter in mm 4 = Pitch in mm Standards Used: ISO 2901 / ISO 2902 / ISO 2903 / ISO 2904 DIN 103 (German standard for trapezoidal threads) Materials: Made of hardened tool steel for durability and wear resistance. Applications: Used in quality control during manufacturing. Ensures compatibility and functional fit between threaded parts.
