Static-Control Precise-Control Screwdrivers

Hex

Also known as ESD-safe screwdrivers, the handle drains static away from your application, preventing buildup from electrostatic discharge (ESD) that can damage sensitive equipment. Press the rotating end cap on the handle with your palm to apply constant pressure while turning the body of the screwdriver with your fingertips.

Static-dissipative drivers divert static electricity faster than antistatic drivers. They meet IEC 61340-5-1 requirements for protecting electronic devices from electrostatic discharge.

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