All of these components are engineered to fit in a slim profile to make these the go-to wrench for pros. 180-degree flex-head box end combined with our slim profile gives you the ultimate flexibility. 12-point WaveDrive box end transfer torque uniformly and prevents damaging and rounding of the bolt. 0 degree offset on the box end gives you maximum clearance.
