Intro to Millwright Practice Exam

The ________ socket has an opening shaped like a six-pointed star for extra torque.

1. Hex

2. Torx

3. Square

4. Round

The correct answer is: Torx

The socket that is shaped like a six-pointed star, allowing for enhanced grip and greater torque, is indeed the Torx socket. This design features a unique pattern of six rounded points or lobes, which not only helps prevent stripping of the fastener but also distributes the force evenly across the surfaces. This results in a strong grip and allows for higher torque applications without the risk of damaging the fastener. The Torx design is widely used in various applications, particularly in the automotive and electronics industries, due to its effectiveness and reliability. In contrast, a hex socket has a six-sided opening and is suited for standard hexagonal screws, but it does not provide the same torque advantages as the Torx. Square and round sockets serve completely different purposes; square sockets are typically used for high-torque applications such as drive sockets, while round sockets are notably less common and usually not designed for torque applications. Thus, the Torx socket is the preferred choice when extra torque and fastener security are paramount.
