The eight-piece and 10-piece, zero-degree Matco SAE Flex Ratcheting Wrench Sets, No. SRFBZXL82T and No. SRFBZXLM102T, are forged with a high-alloy long, slim handle that provides clearance without minimizing torque. The flex head allows angular access to fasteners. These ratcheting wrenches include a 72-tooth flexible head that gains access where standard ratcheting wrenches will not fit, with a minimal 5-degree swing arc. They allow the technician to loosen or tighten any 6-point, 12-point, spline, torx, square, and even up to 50-percent rounded, fasteners.
