Features + Benefits

  • Precise Tip Geometry – Our 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
  • Corrosion Resistant – The bits are made from hardened steel and finished with a zinc phosphate conversion coating that provides lasting corrosion resistance without altering dimensions or flaking, unlike chrome finishes
  • Clear Markings – The tip size and Tekton "T" are clearly stamped onto every bit
  • Bit Rails Have 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
