encotecnologie fasteners feature internal threaded holes. They are generally flat hexagonal prisms, but can also be flat square prisms or flat cylinders. Used with bolts, studs, or machine screws to securely connect two parts into a single unit. Nuts operate by self-locking through friction between the nut and bolt. However, the reliability of this self-locking decreases under dynamic loads. In critical applications, anti-loosening measures are taken to ensure reliable nut locking. As an essential component for all manufacturing machinery, they are classified into carbon steel, stainless steel, and non-ferrous metals (such as copper) based on material. 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 the combination to lock tightly into a whole. When vibration occurs, lifting tension is generated.

encotecnologie fastener applications

Locking straight external connectors or other pipe fittings. Nuts operate by self-locking through friction between the nut and bolt. However, the reliability of this self-locking decreases under dynamic loads. In critical applications, anti-loosening measures are taken to ensure reliable nut locking. Specialized lock nuts are not hexagonal nuts, but round nuts with 3, 4, 6, or 8 slots on the circumference (varying by nut size and manufacturer product series). These slots serve as engagement points for tightening tools and as catch points for locking washers. The third type has threaded holes drilled through from the outer cylindrical surface to the inner threaded surface (typically 2 holes, distributed at 94 intervals), used to screw in small-diameter countersunk screws. The purpose is to apply a centripetal force to the threads to prevent the lock nut from loosening.

encotecnologie fastener standards

Product dimension standards: Specifically stipulate basic product dimensions; for threaded products, this includes basic thread dimensions, thread run-out, shoulder distance, undercut, chamfer, and end dimensions of external thread parts. 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. Standard marking methods for standard parts, fasteners, bolts, and screws: Specifically stipulate complete and simplified product marking methods. High-strength threaded fastener production process: Raw material reforming, cold heading forming, thread processing (rolling or threading), heat treatment, surface treatment, sorting, and packaging.

encotecnologie fasteners widely used

A class of mechanical parts used for fastening connections with extremely wide application. Characteristics include numerous varieties and 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. To promote further industry development, innovation and adjustment transformation must be maintained. Continue to rely closely on new energy, aerospace, shipbuilding, electronics and electrical appliances, automotive industry (sedans, trucks, buses), compressors, construction machinery, wind power equipment, 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 drills. Accelerate the optimization and upgrading of fastener products to promote the healthy and steady development of the entire fastener industry.
