The Craftsman trademark was registered by Sears on May 20, 1927. [2] Arthur Barrows, head of the company's hardware department, liked the name Craftsman and reportedly bought the rights to use it from the Marion-Craftsman Tool Company for $500 (equivalent to $8,770 in 2023). [3] The brand's early customers were mostly farmers.
A socket wrench (or socket spanner) is a type of spanner (or wrench [1] in North American English) that uses a closed socket format, rather than a typical open wrench/spanner to turn a fastener, typically in the form of a nut or bolt. [2] The most prevalent form is the ratcheting socket wrench, often informally called a ratchet.
A ratchet consists of a round gear or a linear rack with teeth, and a pivoting, spring-loaded finger called a pawl (or click, in clocks and watches [1] [2]) that engages the teeth. The teeth are uniform but are usually asymmetrical , with each tooth having a moderate slope on one edge and a much steeper slope on the other edge.
A set of metric spanners or wrenches, open at one end and box/ring at the other. These are commonly known as “combination” spanners. A wrench or spanner is a tool used to provide grip and mechanical advantage in applying torque to turn objects—usually rotary fasteners, such as nuts and bolts—or keep them from turning.
Ratcheting is a progressive, incremental inelastic deformation characterized by a shift of the stress-strain hysteresis loop along the strain axis. [4] When the amplitude of cyclic stresses exceed the elastic limit, the plastic deformation that occurs keep accumulating paving way for a catastrophic failure of the structure.
The cost of the greater torque is lower rotational speed; it is easy for a geared hand drill to achieve a rotational speed of several hundred revolutions per minute, while it would require considerable effort to achieve even 100 rpm with a brace. The front of the brace consists of a chuck spindle with V-shaped brackets or clamps inside.
