The toughest bits available, these withstand the shock and twisting force of impact drivers. Also known as insert bits, use with a bit adapter in power tools.

Insert a bit into the shaft and a magnet holds it in place.

Tamper-resistant hex are also known as pin-in-hex.

Tamper-resistant Torx are also known as pin-in-Torx.

Press down on the handle’s collar to either adjust the shaft length or remove the shaft and replace it to change the tip. Sets include a handle and multiple reversible shafts. The handle has a contoured ultra grip that provides comfort and the best possible grip for achieving maximum torque.

Additional reversible shafts are sold separately.

The handle on these assorted ESD-safe screwdrivers drains static away from your application, preventing buildup from electrostatic discharge (ESD) that can damage sensitive equipment. They meet IEC 61340-5-1 requirements for protecting electronic devices from electrostatic discharge. Press the rotating end cap on the handle to apply constant pressure with your palm while turning the body of the screwdriver with your fingertips.

Warning: Because the handle conducts electricity, screwdrivers must not come in contact with sources of electrical power.

The assorted keys in these sets have a long shaft for more reach and a short shaft for more torque when turning fasteners. The textured ultra grip provides comfort and slip resistance.

The slim body reaches into tight spots to grip and turn screws. Use the magnet at the end of the handle to retrieve dropped fasteners. Screw starters are not intended for final tightening or removal of fasteners.

Starters with wedge tip fit a variety of drive styles. Push the sleeve on the handle forward and insert the tip into screw head. Pull the sleeve back and the tip splits to hold the screw firmly. Once threads are started, the tool releases the screw.

These sets include an adjustable torque driver, bits for different drive styles, and a socket adapter. To adjust torque, remove the black vinyl end cap and turn the attached adjustment key. 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.
