Hexalobular Screws, commonly known as hexalobular torx or star-drive screws, are high-performance fasteners engineered for superior torque transmission and precision assembly. Designed with a distinct six-lobed internal drive, these hexalobular socket screws eliminate the common issue of “cam-out” found in traditional Phillips drives, allowing for tighter, more reliable connections without damaging the screw head or the tool. At Tianqi Fasteners, our range of stainless steel screws—including 304 and 316 grades—combines this advanced drive geometry with exceptional corrosion resistance, making them the preferred choice for automotive, electronics, and marine industries where durability and structural integrity are non-negotiable.
The six-point contact design ensures that driving forces are transferred through surfaces rather than edges, allowing for higher torque without stripping the head.
Unlike cross-recessed screws, the vertical sidewalls of the hexalobular drive prevent the driver from slipping out, reducing operator fatigue and tool wear.
Available in A2 (304) and A4 (316) stainless steel, providing excellent protection against rust, oxidation, and chemical exposure in harsh environments.
Our machine screws adhere to international standards such as pan head and countersunk, ensuring seamless compatibility with global manufacturing lines.
The optimized engagement between the bit and the socket significantly extends the working life of assembly tools, lowering long-term operational costs.
