Ball-End Screwdrivers

Torx

When you don't have exact alignment between the fastener and the tool, the ball end allows angled entry to turn screws in hard-to-reach areas. These screwdrivers have a soft, contoured handle that provides comfort and the best possible grip for achieving maximum torque.

Tamper-Resistant Torx Bits

Hex Shank

Hex Shank for Power Tools

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

Hex shank bits (also known as insert bits) are used in hand drivers or with a bit adapter in power tools.

Hex shank bits for power tools have a groove in the shank and fit directly into power tools without an adapter. They offer more reach for recessed holes and less wobble compared to a hex shank bit used with an adapter.
