Our taps are not just "metric"—they are engineered specifically to the GOST 3266 (ГОСТ 3266-81) dimensional standard. This is the industrial backbone of Russia and the CIS region.
Perfect Fit: The shank diameters and square drive dimensions (k) are precision-ground to fit traditional Russian tap wrenches and specialized Soviet-era machine spindles.
Precision Class: Available in Class 1, 2, and 3 (6H/7H equivalent), ensuring the exact thread fit required for Russian automotive, agricultural, and heavy machinery sectors.
In the Russian market, material performance is non-negotiable. We use HSS 4341, which serves as an excellent high-performance alternative to the Russian 9ХС or Р6М5 grades for general-purpose tasks.
Hardness (HRC 62-64): Through vacuum heat treatment, we ensure the cutting teeth maintain a sharp edge even in cold-weather workshop environments typical of the Siberian or Ural regions.
Enhanced Toughness: HSS 4341 provides the necessary flexibility to prevent snapping during manual "heavy-hand" tapping, a common requirement in MRO (Maintenance, Repair, and Operations) sectors.
These taps are designed for the "Rough and Tough" environments of the Russian industrial landscape:
Heavy Industry & Mining: Ideal for on-site repairs of mining equipment and structural steel threading.
Agricultural Machinery: Perfectly sized for the maintenance of Russian-made tractors and harvesters (e.g., Rostselmash, Kirovets).
Energy & Railway: Essential for threading tasks in the vast Russian railway network and oil/gas infrastructure.
Material Versatility: Optimized for structural steels, low-alloy steels, and cast iron with tensile strengths up to 800 N/mm².

| M3 | 0.50 | GOST 3266 | 48 mm | 11 mm | 3.15 mm | 2.50 mm |
| M6 | 1.00 | GOST 3266 | 66 mm | 19 mm | 6.30 mm | 5.00 mm |
| M10 | 1.50 | GOST 3266 | 80 mm | 24 mm | 10.00 mm | 8.00 mm |
| M12 | 1.75 | GOST 3266 | 89 mm | 29 mm | 9.00 mm | 7.10 mm |
| M16 | 2.00 | GOST 3266 | 102 mm | 32 mm | 12.50 mm | 10.00 mm |
| M20 | 2.50 | GOST 3266 | 112 mm | 37 mm | 14.00 mm | 11.20 mm |
| M24 | 3.00 | GOST 3266 | 130 mm | 45 mm | 18.00 mm | 14.00 mm |
Maritime & Rail Protection: Every tap is treated with heavy-duty anti-rust oil to withstand the high-humidity transit to Vladivostok or the long rail journeys to Moscow.
Professional Branding: Each Rose-Box plastic case includes clear labeling with both Metric and GOST designations to assist with customs clearance and inventory management.
OEM Support: We provide high-definition Laser Etching for Russian private labels, including Cyrillic markings if required.
Q: Can HSS 4341 replace R6M5 (Р6М5) in all applications?
A: For over 80% of general-purpose maintenance and steel fabrication, HSS 4341 is an excellent, cost-effective substitute for Р6М5, offering similar hardness and cutting precision.
Q: Do these taps follow the GOST 3266-81 dimensions?
A: Yes, we strictly follow the 1981 revision of the GOST standard to ensure 100% compatibility with Russian tool holders and equipment.
Q: What is the shelf life in a cold warehouse?
A: Our specialized protective oil ensures a 36-month shelf life, even in unheated warehouses during the Russian winter.
