Thread And Plain Gauges

Features:

• Gauge dimensions are as per DIN 103-9
• Recommended Tolerance classes are 7H/7e for medium tolerance quality and 8H/8c for coarse tolerance quality.

Acceptance criteria for components:
The GO gauge when screwed by hand without using excessive force, should enter and pass the whole length of the workpiece thread. The NOT GO gauge when screwed by hand without using excessive force, should not enter the component by more than two turns of the thread from both ends.

Kuroda Precision Industries: A Brief introduction
Kuroda was founded in 1925 as one of the first dedicated gauge manufacturers in Japan. Since then, they have developed various products based on precision measuring and processing technology. While working to preserve traditional skills, techniques and reputation for best quality, they also employ latest technologies through active R&D. Kuroda’s mission continues to be that of support to the customers through their high precision measuring and processing technology based on the philosophy of P&P (Precision and Productivity) and the spirit of C&C (Challenge and Create).

Features:

Thread Gauge: Multi StartMulti-start threadsMulti start threads are used where quick axial travel is desired with less rotation. These are also used for threads which cannot have coarse pitches due to metallurgical constraints. In comparison to single start threads, multi start threads can accept higher axial thrusts for restricted angles of rotation, the efficiency is high, the tendency to locking is reduced. Multi start threads are commonly used in power transmitting screws, valve spindles.
