The DIN 1470 standard, published by the German Institute for Standardization (DIN), describes the requirements for piloted full-length parallel groove pins. Similarly, the ISO 8739 standard, published by the International Organization for Standardization (ISO), describes the specifications for piloted full-length parallel groove pins made of steel or austenitic stainless steel, having three equally spaced grooves pressed longitudinally on their outer surface (ISO 8739 Grooved pins - Piloted full-length parallel groove). These pins have a nominal diameter from 1,5 mm to 25 mm (inclusive).
Grooved pins defined in these standards are used as removable fixing elements, which can have a cylindrical or conical shape. These pins are suitable for industrial applications such as fastening, compression and pressure. Centers are used to facilitate the positioning of parts to be adjusted by avoiding sharp edges. Die stamping and related products consist of parts formed by cutting or deformation techniques of sheets without chip removal. The main such products are bushings, flanges or springs.
Grooved pins are solid printed fasteners that are rapidly gaining popularity. These grooves have three parallel grooves and are often used as locking devices, pivots, levers or insertion elements. During the manufacture of such threaded pins, the grooves are formed by the forging process, the material is displaced but not removed. The holding power of the grooved pins comes from the radial forces produced when the hammered material is compressed in the hole. Parallel grooves determine where and how long to hold the pin. Pilots are the small non-grooved portions of the pin ends and should not be confused with the longer non-grooved portions of the pin. They appear on a smaller scale than the corrugated part. Pilots simplify setup by creating a starting position. Nominal diameter x nominal length defines the form of the threaded pins. The form is determined by the location of the grooves and the presence of pilots and other features.
Our organization, among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, with its trained and expert staff and advanced technological equipment, within the scope of DIN 1470 standard, for piloted, full-length parallel grooved pins and within the scope of ISO 8739 standard, piloted. It also provides testing services for full-length parallel grooved pins.
