Harbor Freight Tools won a declassification of the class action; that is, the court found that all the individual situations were not similar enough to be judged as a single class, and that their claims would require an individual-by-individual inquiry, so the case could not be handled on a class basis.
Spindle: The shiny cylindrical component that the thimble causes to move toward the anvil. Ratchet stop: Device on end of handle that limits applied pressure by slipping at a calibrated torque. Sleeve, barrel, or stock: The stationary round component with the linear scale on it, sometimes with vernier markings. In some instruments the scale is ...
A ratchet (occasionally spelled rachet) is a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. Ratchets are widely used in machinery and tools. The word ratchet is also used informally to refer to a ratcheting socket wrench.
Socket set with ratchet (above), four hex sockets and a universal joint. 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.
The moving part then decelerates to a stop from the dynamic contact friction. The cycle repeats as the forcing element catches up to contact again. Stick, store spring energy, impulsively release spring energy, accelerate, decelerate, stop, stick. Repeat. Stiction is a problem for the design and materials science of many moving linkages.
Easco Hand Tools was an American manufacturer of hand tools. It is best known for being the main supplier of mechanic's tools for the Craftsman brand. Its tools were also sold under the Allen and KD Tools brands after its acquisition by Danaher Corporation. The brand name was gradually phased out by Danaher.
A friction hitch is a kind of knot used to attach one rope to another in a way that is easily adjusted. These knots are commonly used in climbing as part of single-rope technique , doubled-rope technique and as "ratchets" to capture progress on a moving rope, most typically in a mechanical advantage system such as a Z-drag .
Friction drilling uses a conical bit made of very heat-resistant material such as cemented carbide. This device is pressed against a target material with both high rotational speed and high pressure. That way, there is a high local production of heat which softens the object, making it plastic. The tool then "sinks" through the object, making a ...
