Overview

Designed for Speed and Torque
The front of the handle is round for quick turning and the middle transitions to a tri-lobe shape that provides a secure grip for high-torque driving.

Three Handle Sizes that Scale with the Tips
Drivers with small tip sizes have smaller, more rounded handles for control with precision screws. Drivers with larger tip sizes have bigger, more triangular handles to turn large screws with more torque.

Soft Overmold Grip for Controlled Turning
The handle's red exterior is made of a lightly textured TPE material that is slightly soft and grippy for controlled spinning, fine adjustments, and reduced slipping under torque.

Size Markings in Four Locations
Each driver has the tip size engraved in four locations with high-contrast laser markings.

Flared End Prevents Slipping
The front end of the handle has a tri-lobe shape that flares out to prevent your hand from slipping while you're pushing it forward and turning.

Through-Hole in Handle
Each screwdriver handle has the same size through-hole so you can hang it on a hook. You can also attach a safety lanyard when working at heights to prevent drops.

Tip Geometry and Coating

Our slotted tips have a slight wedge shape that grips both sides of the slot. The inch series uses ASME sizing and the metric series uses ISO sizing for a precise fit in slotted screws.
Each tip is coated with black manganese phosphate, creating a slightly rough surface that enhances screw engagement. The conversion coating produces a uniform, corrosion-resistant layer that preserves tip geometry and resists flaking.

Steel Shank Won't Twist Out
The end of the shank is flattened to form a broad surface that resists twisting inside the handle. The handle is molded around the shank, creating a solid connection that is stronger and straighter than simply pressing the shank into a premade handle.

Materials and Construction

Modular Driver Organizers
Modular pieces click together and hold screwdriver shanks in slots to maintain consistent spacing between drivers and to prevent them from rolling in a drawer. Made of polypropylene, each piece is 1.2 inches tall to fit in shallow drawers.
