Our JIS Bending Nut Machine Taps are engineered for high-volume, continuous threading in dedicated nut tapping machines. Unlike standard machine taps, the Bent Shank (Bending Type) design allows finished nuts to slide over the shank and exit automatically, enabling non-stop production.
By applying an advanced Titanium Nitride (TiN) coating to a premium HSS-M2/M35 core, we've achieved a surface that is both ultra-hard (2300 HV) and extremely smooth. This reduces tapping torque by up to 30% and prevents "nut jamming," making it the ideal choice for Tier-1 fastener manufacturers using Japanese or Taiwanese tapping equipment.

JIS Precision: Our taps strictly follow the Japanese Industrial Standard for shank diameter and thread geometry, ensuring seamless integration with Japanese tapping heads (e.g., Fanuc or specialty nut tapping systems).
Round Shank Design: The precision-ground round shank ensures maximum concentricity, reducing vibration and preventing thread eccentricity during high-speed rotation.
Long Shank Architecture: Designed with extended shanks to accommodate the accumulation of multiple nuts before they are discharged.
Heat Dissipation: Nut tapping generates immense friction heat. The TiN coating acts as a thermal shield, extending tool life by up to 200% compared to uncoated taps.
Low Friction (Lubricity): The gold finish reduces the friction between the tap and the nut, ensuring that nuts slide smoothly along the shank without sticking or galling.
M35 Cobalt Core: For tougher nuts (like Grade 8 or Grade 10 steel), we offer the M35 (5% Cobalt) substrate to prevent edge wear.
Protective Storage: Each bending tap is individually vacuum-sealed in a reinforced Rose-Box plastic tube to prevent bending or chipping during transit.
Batch Consistency: Every tap undergoes 100% thread profile inspection using high-definition optical comparators to ensure a consistent 6H/GH tolerance.
OEM Customization: We support Laser Etching for your logo and specific shank dimensions to help you capture the high-end fastener market.
Q: Can these bending taps be used on standard CNC Machining Centers?
A: No. These are specialty tools designed for Nut Tapping Machines where the shank is bent to allow nuts to flow through. For standard VMC centers, please refer to our JIS Spiral Point series.
Q: How do I choose between M2 and M35 for nut tapping?
A: For standard Carbon Steel or Brass nuts, HSS-M2 is excellent. For Stainless Steel (304/316) or high-tensile alloy nuts (Grade 10.9), we strongly recommend HSS-M35 with TiN coating.
Q: What is the lead time for custom shank lengths?
A: As a specialized factory, we maintain blanks for common JIS sizes. Custom bending and length grinding typically take 10-15 business days.
