Details
Apply High Torque
The handle's three-sided geometry directly engages the structure of your hand, instead of relying on friction with your skin, so you can apply high force with less fatigue.

Spin Fasteners Quickly
Round sections at the front and back ends of the handle allow you to spin long, finely threaded fasteners quickly and continuously.

- Black oxide finish—keep lightly oiled for best corrosion protection
Polypropylene Handle
- Reinforced with calcium carbonate for dimensional stability
- Shore D 68 durometer
Overmolded Grip

- Shore A 80 durometer
![Driver Blades are Insert Molded](https://media.tekton.com/images/details/drivers/screwdrivers/tekton-insert-molded-ht-bo-1x.jpg)
Insert Molded for Exceptional Strength
We use a molding process that forms the handle around the blade, rather than forcing the blade into a premade handle. The result is a straighter blade that can’t twist out.
