stolle fasteners Germany stolle models stolle prices

stolle 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 for self-locking. However, the reliability of this self-locking decreases under dynamic loads. In critical applications, anti-loosening measures are implemented to ensure reliable nut locking. As an essential component for all manufacturing machinery, they are categorized by material into carbon steel, stainless steel, non-ferrous metals (such as copper), and other major types. Each section features interlocking cams; due to the internal wedge design having a slope angle greater than the thread angle of the bolt and nut, this combination locks tightly into a single unit. When vibration occurs, it generates lifting tension.

stolle fastener applications

Locking straight-thread external connectors or other pipe fittings. Nuts operate by using the 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 implemented to ensure reliable 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 catch points for locking washers. A third type features through-holes drilled from the outer cylindrical surface to the inner threaded surface (typically 2 holes, arranged in a 94 distribution on the outer surface) for inserting small-diameter countersunk screws. The purpose is to apply a radial force to the threads to prevent the lock nut from loosening.

stolle fastener standards

Product dimension standards: Specifically define 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. These mainly include standards and specific regulations regarding product tolerances, mechanical properties, surface defects, surface treatments, and product testing. Standards for marking standard parts, fasteners, bolts, and screws: Specifically define complete and simplified product marking methods. High-strength threaded fastener production process: The manufacturing process for high-strength threaded fasteners involves raw material reforming, cold heading forming, thread processing (rolling or threading), heat treatment, surface treatment, sorting, and packaging.

stolle 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 industries (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.
