Square High-Torque Screwdriver Set, 3-Piece (S1-S3)



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.

Durable, Nonslip Handle

The overmolded grip provides a nonslip surface that is permanently bonded to the handle and won't degrade or become sticky over time.

Materials and Construction

High-Torque Square Screwdriver

AISI 8650 Steel Blade

  • Strong Ni-Cr-Mo alloy hardened to HRC 52–56
  • Chrome-plated shaft finish for increased corrosion resistance

Polypropylene Handle

  • Reinforced with calcium carbonate for dimensional stability
  • Shore D 68 durometer

Overmolded Grip

  • Soft thermoplastic elastomer (TPE)
  • Shore A 80 durometer
Driver Blades are Insert Molded

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.
