Tekton screwdrivers have handles that are 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. 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. Handle materials resist most common shop chemicals. Each driver has the tip size engraved in four locations with high-contrast laser markings. 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. Tips are precisely machined and 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 doesn't chip or flake off. 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. This set includes Phillips (JIS compatible) and slotted drivers.
