haslinger fasteners Germany haslinger model haslinger price

haslinger fasteners feature internal threaded holes and are generally shaped as flat hexagonal prisms, though flat square prisms or flat cylindrical shapes are also available. They are used in conjunction with bolts, studs, or machine screws to securely connect two components into a single assembly. Nuts operate by using the friction between the nut and bolt to achieve self-locking. However, the reliability of this self-locking decreases under dynamic loads. In critical applications, anti-loosening measures are implemented to ensure the reliability of the nut locking. As an essential component for all manufacturing machinery, they are categorized by material into carbon steel, stainless steel, and non-ferrous metals (such as copper). Each segment features interlocking cams; due to the internal wedge design where the ramp angle exceeds the thread angle of the bolt and nut, this combination locks tightly into a single unit. When vibration occurs, it generates lifting tension.

haslinger fasteners applications

Locking straight external connectors or other pipe fittings. Nuts operate by using the friction between the nut and bolt to achieve self-locking. However, the reliability of this self-locking decreases under dynamic loads. In critical applications, anti-loosening measures are implemented to ensure the reliability of the nut locking. Specialized lock nuts are not hexagonal nuts but rather round nuts with 3, 4, 6, or 8 slots cut into the circumference (varying by nut size and manufacturer product series). These slots serve both as engagement points for tightening tools and as locking points for anti-loosening washers. The third type involves drilling through-holes with threads from the outer cylindrical surface to the inner threaded surface (typically 2 holes, arranged in a 102 distribution on the outer surface) to accept small-diameter countersunk screws. The purpose is to apply a radial force to the threads to prevent the lock nut from loosening.

haslinger fasteners standards

Standards for product dimensions: Specific provisions regarding basic product dimensions; for threaded products, this also includes basic thread dimensions, thread run-out, shoulder distance, undercuts and chamfers, and end dimensions of external thread components. Standards for technical conditions of fastener products. These mainly include standards and corresponding specific provisions for product tolerances, mechanical properties, surface defects, surface treatment, and product testing. Standards for marking methods of standard parts, fasteners, bolts, and screws: Specific provisions regarding complete and simplified product marking methods. Process flow for high-strength threaded fastener products: The manufacturing process for high-strength threaded fasteners involves raw material modification, cold heading forming, thread processing (thread rolling or thread cutting), heat treatment, surface treatment, sorting, and packaging.

haslinger fasteners widely applied

These are mechanical parts used for fastening connections and are extremely widely applied. They are characterized by a wide variety of specifications, diverse performance and applications, 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, drilling equipment, shipbuilding industry, mining equipment, oil drilling rigs (onshore or offshore), public utilities, rail transit, transmission systems, metallurgical equipment, and rock drilling hammers. Accelerate the optimization and upgrading of fastener products to promote the healthy and steady development of the entire fastener industry.
