Product Description

Internal and external thread bolts, also known as internal and external thread screws or combination screws, represent a unique class of fastening solutions that ingeniously merge the properties of internal and external threads. Distinguished by their versatility, these fasteners are extensively utilized across various domains, including mechanical manufacturing, electronic equipment, and furniture assembly. Below is an intricate exploration of their structural traits, operational mechanisms, prevalent types, potential applications, as well as the benefits and constraints they offer:

• Structural Features

Composite thread design: Expertly engineered with one end featuring an external thread to mate with a nut or an internally threaded hole, while the opposite end contains an internal threaded hole to facilitate connection with other bolts or screws. This duality enables layered fastening of multiple components with precision and reliability.

Diverse head shapes: To cater to a variety of operational scenarios and specific user demands, these bolts come in an array of head designs. Common styles encompass cross grooves, straight grooves, inner hexagonal, and outer hexagonal configurations, ensuring compatibility and ease of use across different applications.

Rich materials: Crafted from a selection of premium materials such as carbon steel, stainless steel, and copper, each choice brings its own set of advantages. Notably, stainless steel is prized for its exceptional resistance to corrosion and robust strength, making it a favored option for enduring performance.

Working Principle: The functional essence of these bolts lies in the interplay between the external thread and the mating internal threaded hole on the connected component. This interaction secures the bolt to one component, while the internal threaded hole links to another screw or bolt, achieving a strong, cohesive assembly of multiple components. The resultant friction and pre-tightening force between threads counteracts loosening, safeguarding the connection's stability.

• Common Types

Equal length internal and external thread bolts: Characterized by an external thread section and an internal thread hole section of approximately equal length, these bolts are ideally suited for joining two components of comparable thickness, providing balanced and effective connections.

Unequal length internal and external thread bolts: With differing lengths between the external thread and internal thread hole sections, these bolts offer versatile application, allowing for adaptation to specific assembly needs. They are particularly beneficial for connecting components with significant thickness disparities.

• Application Scenarios

Electronic Devices: Within the realm of electronic device manufacturing, where space constraints and precise component connections are paramount, internal and external threaded bolts excel in ensuring stable multi-layer circuit board assemblies, housing connections, and more. Their compact nature mitigates traditional bolt-related space and interference issues.

Furniture Manufacturing: These bolts play a crucial role in the assembly of panel furniture, facilitating quick and efficient connections between different panels. This design supports easy disassembly and transportation while maintaining the structural integrity and stability of the furniture.

Mechanical Equipment: Serving as a cornerstone in mechanical equipment assembly, these bolts are frequently employed to secure a variety of components, including motors, brackets, and transmission devices, ensuring a steadfast assembly that upholds the relative stability of each component during operational dynamics.

• Advantages and Limitations

Advantages: These bolts revolutionize the assembly process by reducing component counts, streamlining operations in constrained spaces or around intricate structures. Their design allows for easy disassembly and maintenance, significantly boosting production efficiency and serviceability.

Limitations: Despite their numerous benefits, internal and external thread bolts present certain challenges. Their complex structure incurs higher manufacturing costs compared to standard bolts, and under specific extreme load conditions, they may not match the connection strength provided by singular high-strength bolts.
