berardi bullonerie fastener mechanical parts, cylindrical threaded fasteners used with nuts. A type of fastener consisting of a head and a shank (a cylinder with external threads), which must be used with a nut to tightly connect two parts with through holes. This connection method is called a bolted connection. If the nut is unscrewed from the bolt, its characteristics include a wide variety of specifications, different performance and uses, and a high degree of standardization, serialization, and generalization. Therefore, some people refer to this type of tight bolt fastener that already has national standards as standard fasteners, or simply as standard parts. It can also separate these two parts, so bolted connections belong to detachable connections. Bolts bear important tasks in industry; as long as industry exists on Earth, the function of bolts will always be important.

berardi bullonerie fastener shapes

Generally, countersunk heads are used where a smooth surface without protrusions is required after connection, because the countersunk head can be screwed into the part. Round heads can also be screwed into the part. Square heads allow for greater tightening torque, but their dimensions are large. In addition, to meet the need for locking after installation, some have holes in the head or shank; these holes prevent the bolt from loosening under vibration. Some bolts have a reduced-diameter unthreaded shank, known as waisted bolts. This type of bolt is beneficial for connections subject to variable loads. There are special high-strength bolts for steel structures, with larger heads and changed dimensions. In addition, there are those for special purposes: T-slot bolts are used, most commonly on machine tool fixtures, with a special shape where both sides of the head are cut off. Anchor bolts, used to fix machines to the ground, come in many shapes. U-shaped bolts, as mentioned above. Etc.

berardi bullonerie fastener performance

Advanced bolts are the foundation of high-end mechanical manufacturing, playing a pivotal role. On the surface, bolt output value accounts for only a few percent of the machinery industry. In essence, the added value they bring to key components and equipment is much higher. A type of fastener consisting of a head and a shank (a cylinder with external threads), which must be used with a nut to tightly connect two parts with through holes. This connection method is called a bolted connection. If the nut is unscrewed from the bolt, it can separate these two parts, so bolted connections belong to detachable connections. In terms of products, mid-to-high-end products will accelerate the localization of quality R&D. The entire process, from design, manufacturing, packaging, transportation, and use to disposal, must consider minimal waste, lowest emissions, high resource utilization, and minimal environmental impact, thereby coordinating and optimizing corporate and social benefits.

berardi bullonerie fastener maintenance

Bolted connections require tight contact at the joint interface and sufficient coefficient of friction. When the design drawings do not specify requirements for the treatment of this interface, handle it according to the following regulations: Perform sandblasting or shot blasting on the mating surfaces of high-strength bolts to remove rust, oil, and other impurities. After treatment, protective measures should be taken on the friction surfaces of high-strength bolt connections to prevent contamination with dirt and oil. It is strictly prohibited to make any marks on the friction surfaces of high-strength bolt connections. Special care must be taken to prevent contamination of the connection surfaces during storage in the factory, transportation, and custody at the installation site. The installation unit must pay special attention to protecting the cleanliness of the connection plates and base material connection surfaces, as well as the characteristics of the friction surfaces. Arbitrary grinding of the connection plate surfaces and base material connection surfaces with grinders is not allowed.
