bulte fasteners feature internal threaded holes. They are generally flat hexagonal prisms, but can also be flat square prisms or flat cylindrical shapes. 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 categorized by material into several major types: carbon steel, stainless steel, and non-ferrous metals (such as copper). Each part has interlocking cams. Due to the internal wedge design, the slope angle is greater than the bolt's thread angle, causing the combination to bite tightly into a single unit. When vibration occurs, lifting tension is generated.

bulte fastener applications

Locking straight-thread 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 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 from the outer circular surface to the inner threaded surface (generally 2 holes, distributed in a 103 pattern on the outer surface) to screw in small-diameter countersunk screws. The purpose is to apply a centripetal force to the threads, preventing the lock nut from loosening.

bulte fastener standards

Product dimension standards: Specifically stipulate basic product dimensions; for threaded products, this includes basic thread dimensions, thread run-out, shoulder distance, undercut, 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. 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.

bulte fasteners widely used

A class 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, 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.
