Cost-Effective Comparison of Combination Wrenches: MECH 309 WSU Vancouver Study

Explore the extensive study conducted by the Department of Mechanical Engineering team at WSU Vancouver, focusing on criteria such as cost, microstructure observations, oxidization, hardness, tolerance, and bending/failure. The study compares combination wrenches from Pittsburgh, Master Mechanic, Husky Pro, Craftsman, and Snap-on, analyzing pre- and post-oxidation states, hardness, open-end testing, tolerance, and failure results. Findings reveal that Husky offers the best value, Craftsman is ideal for durability, while Snap-on excels overall despite being costly. Make informed decisions based on this in-depth evaluation to choose the most suitable combination wrench for your needs.

  15. Conclusions • Husky • Best value, good toughness and low-cost • Warranty may not be as good as high-cost wrenches • Snap-on • Performed well but the high cost makes it a lower value • Has excellent warranty and highest failure points • Craftsman • Best choice if failure is a concern • Good value and lifetime warranty • Master Mechanic • Performed adequately • But for $2 more, the best value wrench, Husky, could be purchased instead • Pittsburgh • Low-cost was evident with its low failure points and inconsistency
