The GearWrench S-Shape Reversible Double Box Ratcheting Wrench Set, No. 85299, is a five-piece, metric set. The 12-point ratcheting wrenches feature a slim S-shape design for access to fasteners blocked by obstructions. GearWrench Surface Drive technology puts force on the flats of fasteners, not the corner, for improved durability, better grip and reduced chance of fastener rounding. These wrenches exceed ANSI specifications and are designed to provide reliable performance and long life. The set includes 10mm by 12mm, 11mm by 13mm, 14mm by 16mm, 15mm by 17mm and 19mm by 22mm wrenches. Also available in SAE sizes.
