A torque wrench is used to tighten which device?

A torque wrench is specifically designed to apply a precise amount of torque to fasteners, which is critical in achieving the desired tension without over-tightening or under-tightening. When it comes to options that involve mechanical fastening and require a specific torque specification, a pipe clamp fits into this category best because it typically involves bolted connections that must be tightened to precise pressures to maintain integrity and prevent leaks in plumbing systems.

Using a torque wrench on a pipe clamp ensures that the connections will hold firm under the operational pressures they are subjected to while preventing damage to both the fasteners and the components being secured.

In contrast, a drill chuck is typically tightened by hand or with other types of tools that do not require specific torque measurements. A light bulb involves a simple clockwise turn to install or remove, without the need for torque specifications. Tightening a sheet metal screw additionally does not usually require a torque wrench, as these screws are designed to be driven in until they bite into the material, relying more on the right type of screwdriver than precise torque settings.
