Snug Fit Crescent Wrench, Jacob M. Miterko, Michael E. Buchbinder, Gavin J. Griffith, Andrew J. Jarrett

Williams Honors College, Honors Research Projects

The most commonly used brand of adjustable wrench, a Crescent Wrench, dates back to the early nineteen hundreds. The tolerances associated with the adjustable wheel used by the most common adjustable wrench designs allow the position of the lower jaw to vary while using the tool. These undesired fluctuations in the position of the lower jaw make it difficult to adjust the wrench to the desired position and keep it in position once the desired position is set.

The proposed adjustable wrench design addresses the tolerance issues by constraining the lower jaw with a new mechanism. The mechanism makes minor …
