The variety of small bits allows you to repair mobile devices, laptops, video game consoles, controllers, wristwatches, and a wide range of other small electronics. The bits are made with tight tolerances for a secure fit in small screws, reducing slip and wear—crucial for high-value, sensitive electronics. The tip size and Tekton “T” are clearly stamped onto every bit. The bits are made from hardened 8660 steel (HRC 55–58) and finished with a zinc phosphate conversion coating that provides lasting corrosion resistance without altering dimensions or flaking, unlike chrome finishes.

The rail can also stand upright on a flat surface, making the markings easier to see. High-contrast size markings are printed on the top of the rail.
