ejot 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 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.

ejot fastener applications

Locking straight external connectors or other 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 cylindrical surface to the inner threaded surface (typically 2 holes, distributed in a 104 pattern on the outer surface) 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.

ejot 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 components. Standards for technical conditions of fastener products. Mainly include standards and specific regulations regarding product tolerances, mechanical properties, surface defects, surface treatment, and product testing. Standard marking methods for standard parts, fasteners, bolts, and screws: Specifically stipulate complete and simplified product marking methods. Process flow for high-strength threaded fasteners: The production 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.

ejot fasteners widely used

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, 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.
