Product Description

The double-headed bolt, commonly referred to as a double-headed screw or bolt, is a versatile cylindrical fastener exhibiting threads on both ends, designed to enhance connection integrity across various scenarios. Its primary features and applications include:

Key Features

1. Exceptional Connection Strength: Boasting threads on both ends, these bolts deliver substantial clamping force, ensuring robust and unwavering connections.

2. Simplified Installation and Removal: Perfect for situations where direct bolt connection is challenging, double-headed bolts allow for easy operation by screwing in one end first before securing with a nut.

3. Versatile Adjustability: Available in an array of lengths, double-headed bolts offer flexibility to accommodate varying component thicknesses and installation demands.

4. Extensive Applicability: These bolts find widespread use across mechanical manufacturing, construction engineering, automotive manufacturing, shipbuilding, power, chemical, oil refining, and valve industries, seamlessly connecting diverse materials and component shapes.

Structural Characteristics

1. Bidirectional Threads: Each end of the double-headed stud features threads, which can be oriented either identically or oppositely, tailored to specific requirements.

2. Smooth Central Section: The middle portion usually remains thread-free, presenting a sleek cylindrical section known as a smooth rod.

3. Broad Specifications: Double head bolts come in a variety of dimensions, with thread diameters ranging from M2 to M100 millimeters. Lengths can be customized to user specifications, with threads categorized into coarse and fine types. Coarse threads are indicated by M and nominal diameter, while fine threads are denoted by M and nominal diameter multiplied by pitch.

Materials and Surface Treatment

1. Common Material Selection: Crafted from materials like carbon steel (e.g., Q235, 45# steel), alloy steel, and stainless steel, each offering distinct mechanical properties and corrosion resistance, tailored for diverse working environments.

2. Advanced Surface Treatments: To enhance both corrosion resistance and aesthetic appeal, surface treatments such as electroplating, blackening, oxidation, phosphating, and non-electrolytic zinc coating are commonly applied.

Application Scenarios

1. Large Equipment Connections: Ideal for connecting substantial equipment, including bridges, automobiles, mining machinery, and boilers, where frequent disassembly and replacement are necessary. Double-headed bolts facilitate effortless detachment and reattachment.

2. Thick Connector Solutions: When faced with thick connectors beyond the capacity of standard bolts, double-headed bolts are the solution. One end is embedded into the thicker connector, while the other is secured with a nut.
Double-headed bolts are critical fasteners offering superior connection strength, ease of installation and removal, notable adjustability, and widespread application. Selecting the appropriate double-headed bolts based on specific environmental conditions and connection demands is essential for optimal performance.
