Our GOST 3266 HSS 4341 Taps are specifically manufactured to meet the rigorous dimensional and performance requirements of the Russian State Standard (ГОСТ 3266-81). These straight-flute taps are the industrial workhorse for the Russian and CIS markets, providing a perfect balance of toughness and cutting precision.
Forged from high-quality HSS 4341, these taps are designed for both manual hand-tapping and machine-assisted threading. The Bright Finish ensures a sharp cutting edge, making them highly effective for general-purpose machining in the vast Russian industrial sector.

Cost-Efficiency: HSS 4341 is the ideal choice for high-volume supply to the Russian market, offering 20% more durability than standard carbon steel while maintaining a competitive price point.
Toughness & Resilience: This grade is engineered to handle the heavy-duty maintenance and repair tasks common in the energy, mining, and railway industries in the CIS region.
Sharp Cutting Performance: Precision ground to 6H/7H accuracy, ensuring clean threads in mild steel, structural steel, and non-ferrous metals.
Heavy Machinery Maintenance: Reliable tool for repairing threads in large-scale industrial equipment and tractors.
Construction & Infrastructure: Essential for general steel fabrication and on-site threading for infrastructure projects.
Automotive Repair: Sized to match the standardized metric bolts used in Russian automotive manufacturing (Lada, Kamaz, etc.).
MRO (Maintenance, Repair, and Operations): The "go-to" tap for professional workshops and hardware wholesalers across Russia.
Export-Ready Packaging: Each tap is individually vacuum-sealed in a shockproof Rose-Box plastic case with professional English/Russian-compatible labeling.
Corrosion Shield: Heavy-duty anti-rust oil coating ensures a 36-month safe shelf life, protecting the tools during long-distance rail or sea transit to ports like Vladivostok, St. Petersburg, or Novorossiysk.
Wholesale Support: Reinforced master cartons designed for the rigors of cross-border logistics.
Q: Does your HSS 4341 meet the hardness requirements of GOST 3266?
A: Yes. Our taps are vacuum heat-treated to achieve a hardness of HRC 62-64, exceeding the basic requirements and ensuring a long service life in tough materials.
Q: Are these compatible with old Russian tap wrenches?
A: Yes. The shank and square (k) dimensions follow the GOST 3266-81 standard, ensuring they fit perfectly into traditional Russian tap holders and machine spindles.
Q: Can you provide a GOST certificate or technical documentation?
A: As a professional factory, we can provide full chemical analysis and hardness test reports to support your customs clearance and quality verification in Russia.
