While standard bits are 25 mm long, every bit in this set is 30 mm long to improve your access to recessed fasteners.
The bits are made of S2 steel with a zinc-phosphate coating that resists corrosion.
The size and Tekton “T” is clearly stamped onto every bit.
The flexible rails securely grip the bits so they can’t fall out, while also making it easy to remove any bit one-handed.
