An opening at the tip accommodates the pin in the recess of tamper-resistant hex screws. These are also known as pin-in-hex or pin-in-socket bits.

Hold hex-shank bits in power tools or change how you access and turn fasteners.

Create your own tool by attaching these shafts to a handle, or use with socket wrenches and power tools.

Accurately measure or limit torque to prevent overtightening and damaging fasteners.

Choose from tools that turn screws, nuts, and threaded rod.
