Product Description

The cylindrical hexagon bolt is an essential fastener in mechanical connections, renowned for its reliability and versatility. Below is a detailed overview of its key characteristics:

Structural Characteristics

Cylindrical Head: The head of the bolt is ingeniously designed with a cylindrical, rounded shape that offers an expanded pressure-bearing area. This design ensures the bolt distributes pressure uniformly when tightened, enhancing its performance. It is particularly advantageous in applications requiring a flush surface, as it prevents the issues that can arise from protruding heads, maintaining a seamless and interference-free finish.

Hexagonal Hole: Positioned at the top of the cylindrical head, this hexagonal feature is crafted for efficiency. When an internal hexagonal wrench is used, it allows for superior torque transmission, facilitating the tightening and loosening of the bolt with ease. This ingenious design not only smooths the connection surface for a more refined appearance but also acts as a deterrent against unauthorized disassembly, providing anti-theft and anti-misoperation benefits.

Screw: Equipped with standard external threads, these bolts boast high thread precision, ensuring a snug and dependable fit with corresponding nuts or threaded holes. A variety of lengths are available to suit diverse application needs, accommodating different connection thicknesses with precision.

Material and Surface Treatment

Material: Crafted from medium carbon steel or medium carbon alloy steel, such as 45 steel or 40Cr, these bolts undergo quenching and tempering to achieve excellent mechanical properties, allowing them to withstand substantial tensile and shear forces. For specialized applications, materials like stainless steel and high-strength alloy steel are utilized, meeting rigorous demands for corrosion resistance and high-temperature endurance.

Surface Treatment: These bolts can undergo various surface treatments to enhance their durability and appearance. Galvanizing provides superior corrosion resistance, making them ideal for industrial and outdoor settings. Nickel plating not only enhances the bolt's aesthetic appeal but also its corrosion resistance. Blackening is perfect for applications demanding a specific appearance and rust prevention, offering a sleek black finish with decorative appeal and rust resistance.

Application Area

Cylindrical hexagonal bolts find extensive applications across multiple industries, including mechanical manufacturing, the automotive sector, electronic equipment, and furniture production. In mechanical manufacturing, they effectively connect components like engine cylinder blocks and machine tool beds. Within the automotive industry, they play a pivotal role in assembling chassis, engines, and car bodies. In electronics, they secure circuit boards and casings, while in furniture making, particularly with high-end designs requiring discrete connections, these bolts offer robust fastening solutions without compromising on a sleek and polished aesthetic.
