Turn sockets from above when there's not room to swing a standard wrench handle. The wrench slips to disengage and stop turning the fastener, preventing overtightening. Factory-set wrenches ensure the same torque is reached every time. The torque setting cannot be adjusted. Wrenches come with a calibration certificate traceable to NIST that states the product has passed a test for accuracy.

Also known as ESD-safe screwdrivers, the grip drains static away from your application, preventing buildup from electrostatic discharge (ESD) that can damage sensitive equipment. Turn the collar to adjust torque. When set torque is reached, these drivers slip to disengage and stop turning the fastener, preventing overtightening. They come with a calibration certificate that is traceable to NIST and includes the test measurements that confirm accuracy. Drivers have a contoured ultra-grip handle that provides comfort and the best possible grip for achieving maximum torque. The torque adjustment mechanism locks to prevent accidental changes to your setting. Use with screwdriver bits (not included).

T-handle drivers include a removable T-bar for extra leverage when apply high torque.

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