A Torx bolt is a specific type of fastener commonly used in bicycle repair and maintenance. Unlike regular hex bolts, it has a star-shaped pattern (six-pointed star) that requires a special Torx tool to work with. Bike manufacturers use these bolts because they provide better grip, are less likely to strip, and can handle more torque when tightening. You might also hear them called "star bolts" or "six-point bolts" in repair manuals. These are especially common in high-end bikes and critical components where regular bolts might come loose.
