Product Description

The Double-headed bolt, also renowned as the double-headed screw, presents itself as a cylindrical fastener equipped with threads on both ends. Its quintessential characteristics and diverse application scenarios are as follows:

Main Features

1. Exceptional Connection Strength: With threads on both ends, it delivers a substantial clamping force, ensuring an unwavering firmness in the connection.

2. Effortless Installation and Disassembly: In scenarios where direct bolt connections are cumbersome, these bolts shine. Simply screw in one end, then affix the nut, making operations a breeze.

3. Adaptability: Choose from varying lengths of double-headed bolts tailored to the thickness and specific installation requirements of the components, offering a remarkable degree of adjustability.

4. Vast Applicability: These bolts find their place across diverse sectors—mechanical manufacturing, construction engineering, auto manufacturing, shipbuilding, energy, chemical, oil refining, valves, and more—to connect a plethora of materials and shapes.

Structural Characteristics

1. Dual End Threads: Threads adorn both ends of the double-headed stud, in either identical or opposing directions, as dictated by specific requirements.

2. Smooth Central Section: A double-headed stud typically features a non-threaded, smooth cylindrical section in its center, aptly named the smooth rod.

3. Diverse Specifications: Available in a variety of sizes, these bolts boast thread diameters from M2 to M100 millimeters. Lengths are customizable to user specifications. Threads are categorized into coarse and fine, represented by M and nominal diameter, with fine threads incorporating pitch.

Materials and Surface Treatment

1. Popular Materials: Carbon steel (e.g., Q235, 45# steel), alloy steel, and stainless steel are common choices for double-headed bolts. Each material offers unique mechanical properties and corrosion resistance, catering to varied working environments.

2. Surface Treatment: To enhance corrosion resistance and visual appeal, surface treatments are standard. Techniques include electroplating, blackening, oxidation, phosphating, and non-electrolytic zinc coating.

Application Scenarios

1. Large Equipment Assembly: These bolts are indispensable in connecting massive equipment—bridges, automobiles, mining machinery, boilers, etc.—where frequent accessory disassembly is needed, facilitating smooth operations.

2. Thick Connectors: For substantial connector thicknesses that exceed ordinary bolt capacities, double-headed bolts are ideal. Insert one end into the thicker connector, securing the other end with a nut to a secondary connector.
Double-headed bolts stand out as vital fasteners, offering high connection strength, ease of installation and disassembly, remarkable adjustability, and broad applicability. When deploying them, it's crucial to select the right bolts based on the specific environment and connection needs.
