12-piece set includes a range of 4 mm bits commonly used in smart phones and other electronics: Y000-Y2 Y-point, PL1-PL6 pentalobe, and standoff bits.
Features:- 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.
- 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.
- 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.
