Westward 4JMA8 Combination Wrench Set Metric combination wrenches offer versatility and functionality for tackling various fastening tasks. They feature a key advantage over standard wrenches: a 12-point box end. This design, with its additional grooves, grips fasteners securely at more angles compared to a 6-point wrench. This allows for easier fastener engagement and better access in tight spaces. On the other end, the wrench boasts an open-ended design. This provides additional flexibility when obstructions limit the use of the box end. Unlike the box end, which typically requires access from directly above the fastener, the open end allows you to apply force from the side.
