Double Point Screw

Double-point screws are headless screws with rotating threads at both ends. They can be entirely composed of machine screws on both ends or a combination of wood screws and machine screws. These screws have two pointed ends that can be inserted into two surfaces, forming a hidden joint. They are used to connect two pieces of wood or two movable parts. The screw rod refers to a threaded connection component that is machined into a screw thread and can transmit precise motion and power. M8 double-ended dowel screws indicate that the screw has a diameter of M8 and both ends are threaded. Hanger bolts generally refer to bolts that are threaded at both ends, with one end screwed into a threaded hole in a component and the other end used to mount a hanging part.

Products Description

The Double Point Screw is characterized by its threaded sections on both ends, with or without a non-threaded center shank. This dual-threaded construction is critical in applications where a component must be fastened into two separate parts, such as embedding into wood or metal while securing another part with a nut or tapped hole. Depending on design, one end may be machine-threaded while the other is wood-threaded or self-tapping for specialized fastening use.

These fasteners are designed for environments requiring high-strength load-bearing capacity and are frequently used in machinery, construction, furniture assembly, electrical supports, pipe hangers, and automotive structures. The absence of a head allows for embedding in a material surface, offering a clean and space-saving connection.

Material Selection: Advantages of Steel

Carbon Steel

Carbon steel is characterized by its relatively low cost and high strength. It offers good machinability and can be processed into various sizes and specifications of Double-Thread Screw. After appropriate heat treatment, its mechanical properties can be improved to meet the performance requirements of general industrial applications.

Alloy Steel

Alloy steel contains alloying elements such as chromium, nickel, molybdenum, and vanadium, which enhance its mechanical properties and physical, and chemical properties. Compared to carbon steel, alloy steel offers higher strength, toughness, hardness, and fatigue resistance. It also exhibits better high-temperature strength and creep resistance, as well as superior low-temperature performance and corrosion resistance for the Two-End Stud.

Stainless Steel

Stainless steel has good corrosion resistance, acid resistance, heat resistance, and low-temperature strength. It can withstand atmospheric corrosion and chemical media corrosion in various environments, maintaining stable performance over a wide range of temperatures. Stainless steel Double-Ended Threaded Bars are ideal for use in harsh environments such as coastal areas, chemical plants, and food processing industries.

Multiple Model Customization Capabilities and Adaptation

Customization Options

Twin-End Bolts can be customized in various ways to meet the specific needs of different applications. This includes customizing the thread length, screw diameter, head type, and material. For example, in the aerospace industry, screws with specific thread pitches and lengths may be required to meet the strict design requirements of aircraft structures.

Adaptability to Different Applications

Two-sided bolts can be adapted to a wide range of applications. They can be used in applications where a high level of precision is required, such as in the assembly of precision machinery, or in applications where a strong and secure connection is needed, such as in construction and heavy machinery.

Application Scenarios

Construction and Structural Engineering

Used in concrete formwork systems, suspended ceilings, and framework anchoring. Often employed to secure structural members or mount components with minimal visible hardware.

Furniture Manufacturing

The M8 Double Ended Dowel Screw is particularly popular in modular and flat-pack furniture assembly, where two panels or frames must be joined securely but also allow for future disassembly.

HVAC and Electrical Support Systems

Hanger Bolts are widely used to mount electrical conduits, ventilation ducts, or piping systems from ceilings or walls.

Automotive and Machinery

Two-end Stud Bolts are used in engine assembly and machinery components where parts are bolted together with a nut on one end and the other embedded in a housing or fixture.
