This package includes a full set of super stubby bits and a 12mm double wrench to work the bits.
Hex Bits: H3/H4/H5/H6/H7/H8/H9/H10/H12/H14
Torx Bits: T10,15,20,25,27,30,40,45,50,55
M Bits (12 pt): M4,5,6,8,10,12,14,16
Simply snap the bits to the wrench side to crack a bolt, then swap to ratchet side to use as a speed wrench. The super low profile (20mm height when bit inside wrench) are time saving when working at tight areas of many European engines, brake assemblies and cabins.
The base of these bits are 12mm hex and universally compatible with your existing tools.
