Our Long Shank Nut Machine Taps are specifically designed for the high-volume production of industrial nuts. Unlike standard machine taps, the elongated shank allows multiple finished nuts to accumulate on the tool during the continuous tapping process of automatic nut-tapping machines.
Manufactured from premium HSS-M2 or HSS-E M35 Cobalt, these taps offer exceptional torsional strength and wear resistance. Every thread is CNC ground to ensure a consistent 6H tolerance, providing the precision required for Tier-1 automotive and industrial fasteners.

Extended Reach (Long Shank): The long shank architecture is optimized for automated discharge systems, reducing machine downtime and increasing parts-per-hour (PPH).
Short Thread Length (Lc): Designed to reduce friction and torque during the through-hole tapping of standard nut thicknesses.
Precision Shank (d): The shank diameter is engineered to be slightly smaller than the minor diameter of the thread, allowing finished nuts to slide smoothly over the shank without jamming.
Substrate Performance: Choose HSS-M2 for standard carbon steel nuts or HSS-E M35 (5% Cobalt) for high-tensile (Grade 8/10) or stainless steel nuts.
Surface Integrity: Fully ground thread profiles with a high-polish finish to minimize friction and prevent material galling.
Chip Management: The straight flute design provides excellent rigidity, essential for the high-torque environment of industrial nut machines.
Q: Why is the bottom hole size for M12 listed as 9.00mm?
A: Note that nut taps often follow specialized tolerances for fastener manufacturing. Always verify your required thread engagement percentage (usually 65%-75%) before selecting your final drill size.
Q: Can these taps be used on a standard CNC VMC?
A: While possible, these are specialty Nut Taps optimized for continuous flow. For standard CNC blind-hole or through-hole applications, we recommend our Spiral Point or Spiral Flute series.
Q: Do you offer custom shank lengths or bending for these taps?
A: Yes. As a professional factory, we can customize the total length (L) and shank configurations to match your specific automatic tapping equipment.
