hex screwdriver

Hex screwdriver shafts are commonly made from S2 tool steel, while handles are often molded from slip-resistant plastics such as ABS with TPR overmolds for grip.

Many hex screwdrivers use magnetic tips to hold and lift screws, helping prevent small fasteners from dropping or getting lost during use.

Insulated T-handle hex screwdrivers are commonly individually tested to 10,000 V AC and carry a working rating of 1,000 V AC for use on energized equipment.

Professional hex drivers often use a black oxide finish for corrosion resistance and are made from through-hardened steel with a hardness around 58–60 HRC.

S2 tool steel is commonly used for screwdriver bits, while hex nut sockets and related components in sets are often made from chromium–vanadium (CR‑V) steel.

Some hex drivers include a dual-position handle that switches between inline and pistol-grip orientations, plus a 1/4" hex quick-change chuck for fast bit swaps.

Compact multi-bit drivers typically provide in-handle storage or an internal compartment that holds multiple bits for easy access and portability.

Precision sets commonly include around 30 bits and a flexible extension shaft for hard-to-reach places. One example configuration lists 7 flat, 6 Phillips, 8 hex and 9 star bits plus a flexible extension.
