2. Cold working - Wikipedia

   en.wikipedia.org/wiki/Cold_working

   In metallurgy, cold forming or cold working is any metalworking process in which metal is shaped below its recrystallization temperature, usually at the ambient temperature.. Such processes are contrasted with hot working techniques like hot rolling, forging, welding, etc. [1]: p.375 The same or similar terms are used in glassmaking for the equivalents; for example cut glass is made by "cold ...

3. Work hardening - Wikipedia

   en.wikipedia.org/wiki/Work_hardening

   The effects of cold working may be reversed by annealing the material at high temperatures where recovery and recrystallization reduce the dislocation density. A material's work hardenability can be predicted by analyzing a stress–strain curve , or studied in context by performing hardness tests before and after a process.

   Thus "fasten using FN7" refers to a fastener that is "find number" 7 in the list. FoS: feature of size: A type of physical feature on a part. An FoS is a feature that can have size associated with it, usually involving the opposition of two surfaces (e.g., the two diametrically opposite sides of a hole wall; the two opposite walls of a slot or ...

5. Swaging - Wikipedia

   en.wikipedia.org/wiki/Swaging

   A finishing operation, shaping, cold works the points on the tooth sides to flats. It might be considered as a side swage. This slightly reduces the tooth width but increases the operating time between "fittings". Swaging is a major advance over filing as the operation is faster, more precise and greatly extends the working life of a saw.

   Although they are usually used to attach pipe and fittings to mechanical supports in buildings, they do not connect the pipes. Fasteners commonly used with piping are a stud bolt [26] with nuts (usually fully threaded, with two heavy, hexagonal nuts); a machine bolt and nut; or a powder-actuated tool (PAT) fastener (usually a nail or threaded ...

   A lip wider than the hole prevents it from falling behind the wall, and often features such as cleats/spikes prevent it from rotating when being compressed. A machine screw is screwed into the sleeve, causing the anchor to bend, expand, spread and grip against the inside of the hole or behind it (in hollow contexts such as drywall over stud ...
