Details

The tip of a tamper star 4 mm bit in a bit driver.

Precise Tip Geometry and Stamped Markings

Tekton 4 mm 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.

Comparison between Tekton bit and Wiha bit after 48 hours in a saltwater solution. The Wiha bit has more corrosion.

Hardened Bits with Non-Flaking Protective Finish

The bits are made from hardened 8660 steel (55–58 HRC)* and finished with a zinc phosphate conversion coating that provides lasting corrosion resistance without altering dimensions or flaking, unlike chrome finishes.

* Line Head bits are made of hardened AISI 1015 steel (40 HRC)

Bit Rails Have a Soft, Secure Hold

The flexible rails securely grip the bits so they can’t fall out, while also making it easy to remove any bit one-handed. The rails can also stand upright on a flat surface, making the markings easier to see.
