8Pcs Folding Tamper-Proof Star Key Wrench Set(T5, T6, T7, T8, T9H, T10H, T15H, T20H)

The 8-piece folding tamper-proof star key wrench set you mentioned is a set of tools commonly known as Torx key wrenches or Torx drivers. These tools are designed to tighten or loosen screws with Torx (also known as star or six-pointed) heads, which have a star-shaped recess instead of the typical flat or Phillips head.

The set you mentioned includes eight different sizes of Torx key wrenches: T5, T6, T7, T8, T9H, T10H, T15H, and T20H. The “T” followed by a number represents the Torx size, with the number indicating the size or diameter of the star-shaped head. The “H” designation in some sizes (T9H, T10H, T15H, T20H) stands for “Hole” and indicates that these wrenches have a hole in the center, allowing them to be used on tamper-proof screws that have a pin in the center.

The folding feature of the set means that the wrenches can be folded or nested into a compact form for easy storage and portability. This makes it convenient to carry the set in a toolbox or pocket.
