The GearWrench 16-Pc Metric Combination Ratcheting Wrench Set, No. 9416, offers 12-point, long pattern wrenches that are made of premium alloy steel with a bright full polish chrome finish. The wrenches range in size from 8mm to 24mm. Long beams provide extra access to hard-to-reach fasteners as well as additional leverage. The ratcheting box ends need as little as 5-degrees to move fasteners compared to the 30-degrees for standard wrenches. The wrench set features Surface Drive technology, which provides off-corner loading for better grip and reduced fastener rounding.
