The History of Wrenches: From Solymon Merrick to Modern Varieties

Introduction to Wrenches

In today's society, there are various types of wrenches, including pipe wrenches, chain wrenches, socket wrenches, torque wrenches, impact wrenches, and more. Wrenches typically feature notches at the mouth for gripping and are pulled at a right angle to the axes of the lever-action and the bolt or nut.

The First Patented Wrench

Did you know when the first wrench was patented, and who the pioneer of the wrench was? The history of wrenches can be traced back to 1835, approximately 200 years ago...

While the concept of wrench typology existed in prehistoric times, it wasn't until August 17, 1835, that Solymon Merrick patented the first wrench. Merrick's patented idea was executed and issued several years later.

Evolution of Wrench Patents

Following Merrick's invention, numerous other wrenches were patented and issued. Interestingly, it wasn't just mechanics who applied for wrench patents; individuals from various walks of life, including steamboat firefighters and heavyweight boxing champions, also contributed to the evolution of wrenches.
