GY NMT Nut Screwing Taps

Coarse Pitch

As per IS: 6175 Part 5 & DIN 357

Nut Screwing Taps, manufactured in accordance with IS: 6175, are specialized cutting tools designed specifically for the high-production threading of nuts. Unlike standard hand taps, these are engineered to handle the unique stresses of continuous nut tapping, ensuring concentricity and thread accuracy across large batches.

Key Features

• Extended Lead Chamfer: These taps typically feature a very long lead (chamfer) length, often covering 10 to 15 threads. This distributes the cutting load over many teeth, reducing wear and allowing for smoother entry into the nut blank.
• Longer Shank: The shank is significantly longer than standard taps. This design allows multiple tapped nuts to collect on the shank during a single operation before they are cleared, making them ideal for use on automatic nut-tapping machines.
• Material and Hardness: Manufactured from premium High-Speed Steel (HSS), these tools are heat-treated to maintain a high red-hardness, ensuring the cutting edges remain sharp even under the thermal stress of high-speed manufacturing.
• Thread Profile: Designed for ISO Metric Coarse Threads, ensuring full compatibility with international fastening standards.
