Product Description

Internal and external thread bolts, affectionately known as combination screws, are a marvel of engineering that blend the functionality of internal and external threads into one versatile piece. These fasteners are indispensable across a spectrum of industries, from mechanical manufacturing and electronics to furniture assembly and beyond. Below, we explore the intricate structural characteristics, ingenious working principles, popular types, diverse application scenarios, as well as their compelling advantages and certain limitations:

• Structural features

Composite thread design: This brilliant innovation features one end with an external thread, perfectly engineered to harmonize with either a nut or an internal-threaded aperture. Meanwhile, the opposite end flaunts an internal threaded hole, ready to seamlessly connect with other bolts or screws, effortlessly achieving a multi-layered fastening of various components.

Diverse head shapes: To cater to a plethora of usage scenarios and operational demands, these bolts showcase an assortment of head shapes. Common configurations include cross grooves, straight grooves, inner hexagonal, and outer hexagonal designs, all tailored for specific utility and ease of use.

Rich materials: Crafted from premium materials such as carbon steel, stainless steel, and copper, these bolts are built to last. Notably, stainless steel is a popular choice, celebrated for its exceptional corrosion resistance and robust strength.

Working principle: The magic lies in screwing the bolt's external thread into the internal thread hole of the connected part, anchoring it securely. Subsequently, the internal threaded hole welcomes another screw or bolt, creating a tight-knit connection of multiple components into a unified whole. The friction and pre-tightening force between the threads work in tandem to prevent loosening, ensuring a steadfast, stable connection.

• Common types

Equal length internal and external thread bolts: These bolts boast an equal length for both the external thread section and the internal thread hole section, making them ideal for connecting components of similar thickness with precision and balance.

Unequal length internal and external thread bolts: Tailored for flexibility, these bolts offer differing lengths between the external thread section and the internal thread hole section. This adaptability suits various assembly requirements, especially for connecting components with significantly different thicknesses.

• Application scenarios

Electronic devices: In the realm of electronics, where space is a premium and precision is paramount, internal and external threaded bolts provide unparalleled stability. They skillfully connect multi-layer circuit boards, casings, and other components, deftly avoiding the spatial constraints and interference issues often caused by overly lengthy traditional bolts.

Furniture manufacturing: In the world of panel furniture, these bolts are the heroes of assembly. They deftly connect different panels, facilitating swift assembly and disassembly for transportation, while steadfastly ensuring the structural integrity of the furniture.

Mechanical equipment: Within mechanical equipment, these bolts are vital for securely connecting various components, such as motors, brackets, and transmission devices. They ensure that each element remains firmly in place, contributing to the overall stability during equipment operation.

• Advantages and limitations

Advantages: They streamline the assembly process, cutting down on parts and complexity; Perfect for connections in tight spaces or with special structural needs; Simplifying disassembly and maintenance, they significantly boost production efficiency and ease maintenance tasks.

Limitations: While they offer many advantages, internal and external thread bolts come with a more complex structure and higher manufacturing costs than ordinary bolts. Additionally, under certain extreme load conditions, their connection strength may not match that of a single high-strength bolt.
