spb visserie fasteners Germany spb visserie models spb visserie prices

spb visserie fasteners feature internal threaded holes. Their shape is generally a flat hexagonal prism, but they can also be flat square prisms or flat cylindrical prisms. Used with bolts, studs, or machine screws to securely connect two parts into a single unit. The operating principle of a nut relies on friction between the nut and bolt for self-locking. However, the reliability of this self-locking decreases under dynamic loads. In critical applications, anti-loosening measures are taken to ensure the reliability of the nut locking. An essential component for all manufacturing machinery, classified by material into carbon steel, stainless steel, non-ferrous metals (such as copper), and other major types. Each part has interlocking cams. Due to the internal wedge design, the slope angle is greater than the thread angle of the bolt and nut, causing this combination to bite tightly into a whole. When vibration occurs, lifting tension is generated.

spb visserie fastener applications

Locking through-thread external connectors or other pipe fittings. The operating principle relies on friction between the nut and bolt for self-locking. However, the reliability of this self-locking decreases under dynamic loads. In critical applications, anti-loosening measures are taken to ensure the reliability of the nut locking. Specialized lock nuts are not hexagonal nuts, but rather round nuts. There are 3, 4, 6, or 8 slots cut into the circumference of the nut (varying by nut size and manufacturer product series). These slots serve both as engagement points for tightening tools and as catch points for locking washers. The third type involves drilling through-threaded holes (generally 2 in number, distributed at 98 intervals on the outer circular surface) from the outer circular surface to the inner threaded surface. These are used to screw in small-diameter countersunk screws, applying a centripetal force to the threads to prevent the lock nut from loosening.

spb visserie fastener standards

Product dimension standards: Specifically stipulate basic product dimensions; for threaded products, this includes basic thread dimensions, thread run-out, shoulder distance, undercuts, chamfers, and end dimensions of external thread components. Standards for technical conditions of fastener products. Mainly include standards for product tolerances, mechanical properties, surface defects, surface treatment, and product testing, along with corresponding specific regulations. Standards for marking standard parts, fasteners, bolts, and screws: Specifically stipulate complete and simplified product marking methods. High-strength threaded fastener production process: raw material modification, cold heading forming, thread processing (rolling or threading), heat treatment, surface treatment, sorting, and packaging.

spb visserie fasteners widely used

A category of mechanical parts used for fastening connections with extremely wide application. Characteristics include a wide variety of specifications, diverse performance and uses, and a high degree of standardization, serialization, and generalization. Therefore, some refer to fasteners with national standards as standard fasteners, or simply standard parts. This can promote further industry development. It is essential to persist in innovation and adjustment/transformation, continuing to rely closely on new energy, aerospace, shipbuilding, electronics and electrical appliances, automotive industry (sedans, trucks, buses), compressors, construction machinery, wind power equipment, fasteners for agricultural machinery, casting industry, drilling equipment, shipbuilding industry, mining equipment, oil drilling rigs (onshore or offshore), public utilities, rail transit, transmission systems, metallurgical equipment, and rock drills. Accelerate the optimization and upgrading of fastener products to promote the healthy and steady development of the entire fastener industry.
