Slotted Bits

Hex Shank

Hex Shank for Power Tools

Strong and durable, these multipurpose bits are often used with power tools to install sheet metal screws.

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.

Slotted Bits for Stainless Steel Screws

Protect your stainless steel screws by using a stainless steel bit. If steel flakes off a standard bit and into the recess, it can lead to rust and contamination. These bits eliminate that risk. Also known as insert bits, use in hand drivers or with a bit adapter in power tools.

Torque Screwdriver and Bit Sets

These sets include an adjustable torque driver, bits for different drive styles, and a socket adapter. Turn the collar on the driver to adjust torque. When set torque is reached, the driver slips to disengage and stop turning the fastener, preventing overtightening. Sets come with a calibration certificate that is traceable to NIST and includes the test measurements that confirm accuracy.

Note: Accuracy ratings do not apply to the lower 20% of the torque range.
