Two Decades of Precision Engineering Excellence

From a Sino-Taiwanese joint venture to a global leader in industrial torque solutions.

TK Group, formerly a Sino-Taiwanese joint venture founded in 2006, is an integrated enterprise combining trade, scientific research, and manufacturing. Our sub-brands include TKWRENCH, TAC, SMG, and Roarktools. Leveraging the latest technology, we develop and manufacture high-quality innovative products for the bolting industry.

The company has introduced advanced German tool design and manufacturing technology, utilizing 3D modeling and finite element analysis (FEA) for optimized design. Combined with practical requirements from large-scale equipment installation and maintenance in China, we specialize in solving fastening and disassembly challenges for large bolts and nuts.

We have imported world-class gear shaping machines, hobbing machines, and grinding machining centers to ensure UM-level part tolerances. TKWRENCH is committed to precision torque control technology, delivering modern technology and first-class quality bolting connection equipment.
