Attach a socket to the 1/4" square drive tip to turn hex nuts and hex head screws. Turn the collar to adjust torque. When set torque is reached, these drivers signal with an audible click. Drivers come with a calibration certificate that is traceable to NIST and includes the test measurements that confirm accuracy.
Note: Accuracy ratings apply to the entire torque range.

Choose a handle based on torque and change shafts to use a different size or drive style. Handles are factory set to ensure you reach the same torque every time. They signal with an audible click when the set torque is reached. The torque setting cannot be adjusted. Handles have a contoured ulta grip for comfort. They come with a calibration certificate that is traceable to DIN and includes the test measurements that confirm accuracy.

Attach a socket to the 1/4" square drive tip to turn hex nuts and hex head screws. The dial on these drivers shows how torque measurements change as you turn. Use to fasten to a specific torque, determine fastener torque specifications, and identify the torque required to loosen tightened fasteners. To use with screwdriver bits, add a bit adapter. Drivers come with a calibration certificate that is traceable to NIST and includes the test measurements that confirm accuracy.
Drivers with memory pointer indicate the maximum torque reached.
Drivers with 1/4" female square drive in handle allow you to attach a T-handle or ratchet to the end for extra leverage when applying high torque.
Note: The accuracy ratings do not apply to the lower 20% of the torque range.

Designed to withstand high torque and force, these adapters fit the square drive on impact wrenches. They accept hex-shank bits (also known as insert bits).
Lock your bit into the adapter to prevent accidental disengagement. These adapters fit square-drive tools and accept hex-shank screwdriver bits.
To secure a bit in adapters with quick-change chuck, pull back on the chuck to insert the bit and then push it forward to lock the bit place.
To secure a bit in twist-lock adapters, tighten the knurled end.
Adapters that have nonmagnetic bit holders won’t attract loose metal parts and shavings.
