The open-end wrench plug consists of two open-ended jaws at each end, each designed to fit specific bolt sizes. The jaws are angled at 15 degrees to facilitate easier access to bolts in tight spaces. The tool operates by applying torque to the bolt head, either tightening or loosening it as required. The chrome-vanadium steel construction ensures the wrench can withstand high stress without deformation. The ergonomic handle provides a firm grip, reducing hand fatigue during prolonged use. This design ensures efficient and safe operation in various mechanical applications.
