Development history and classification of self - tapping screws and rivets

The earliest rivets were small studs made of wood or bone, and the earliest metal deformities are probably the ancestors of rivets as we know them today.There is no doubt that they are metallic connection method of the oldest known to mankind, can be traced back to the original use wrought metal so far, for example: the Bronze Age and the egyptians the slot type wheel with the perimeter of six wooden door riveting fastening together, form the greeks successfully cast in bronze statue, large riveting components together with it.

When h.v. white of the British aircraft company first patented blind rivets for single-sided riveting in 1916, few expected them to be so widely used today.From aerospace to office machines, electronics and playground equipment, it can be said that blind rivets have become an effective and stable method of mechanical connection.

It is not clear when the rivet was invented, but the harness was invented in the 9th or 10th century.Riveting harnesses, like nailed horseshoes, freed slaves from heavy labor, and rivets led to important inventions such as iron pliers for copper and iron workers and wool clippers.

Solid rivet:

A part that is connected to a rivet by its own deformation or interference.Solid rivets are generally aluminum, copper, iron and other materials, surface treatment for white zinc plating.A rigid connection applied to a connector by means of a rivet that is not removable.Small rivet can be cold rivet, large rivet is in the red hot state of hot rivet.Solid rivet can be widely used in cutting tools, stationery account books, locks, helmet automotive hardware bags, children's carts, automotive clutch steel, motorcycle accessories and household appliances. 

Hollow rivet:

Riveting machine (equipment) is required to rivet, rivet after the back is turned, flat rivet.The hollow rivet is composed of the body of the hollow rivet and the core of the rivet, and the body of the hollow rivet is composed of the shaft and the flange at one end of the shaft.The head is formed on the spindle end is inserted into the ontology and rivet is turning to the flange of the end of the rivet body axis position, make the broken part from the diameter of the spindle axis began running a strong tensile fracture and hole enlargement and make the rivet body axis deformation, by this part of the axis of the deformation and the flange on the panel is installed components to install.Hollow rivets are light in weight and weak in head. They are used for riveting non-metallic materials with small load.
