Product Description

Introducing the versatile External Thread Anchor Bolt, a quintessential fastening solution designed for seamless mechanical fastening and anchoring. Its ingenious design utilizes threads on its outer shell, in harmony with a nut, a connected component, or a substrate to ensure robust connections. Below is an elaborate guide explaining its multifaceted dimensions:

• Structural Design

Screw Body: The screw's outer surface is elegantly enveloped in threads, typically boasting a circular cross-section. Classified into coarse and fine threads, each serves a unique purpose. Coarse threads are characterized by their larger profile and broader pitch, facilitating swift installation with heightened strength. Conversely, fine threads feature a smaller profile and narrower pitch, offering exceptional self-locking and anti-loosening capabilities, ideal for environments subjected to shock, vibration, or requiring precision adjustments.

Head Type: The head of the anchor bolt is adaptable, tailored to specific scenarios and installation needs. The hexagonal head is engineered for effortless tightening with a wrench, ensuring balanced force distribution. The countersunk head allows for a smooth and aesthetically pleasing surface post-installation. Additionally, the hexagonal head is perfect for constrained spaces, requiring minimal operating room.

Length Specifications: With lengths spanning from mere millimeters to several meters, they cater to diverse needs. Shorter bolts are ideal for thin plate connections, while the elongated variants excel in deep hole anchoring, adeptly accommodating materials or structures of varying thicknesses.

• Materials and Properties

Material Selection: Anchor bolts are crafted from an array of materials like carbon steel, stainless steel, and alloy steel. Carbon steel is cost-effective and strong, suitable for standard environments. Stainless steel offers outstanding corrosion resistance, perfect for corrosive settings such as humid, acidic, or alkaline conditions. By incorporating specific alloying elements, alloy steel significantly boosts its strength, toughness, and resilience to high temperatures, fulfilling the demands of specialized working environments.

Mechanical Properties: These bolts are endowed with high tensile and shear strength, meticulously designed to endure substantial axial tension and lateral shear forces, thus guaranteeing the stability of connections or anchored components. Many external thread anchor bolts also demonstrate commendable toughness and ductility, adeptly absorbing external impacts to mitigate the risk of brittle fractures.

• Working Principle

Conventional Connection: In a typical usage scenario, the anchor bolt collaborates with a nut. By rotating the nut, it moves axially along the anchor bolt's thread, producing a tightening force that securely clamps and fastens two or more components. Leveraging the friction and inherent self-locking traits between the threads, the connection's reliability is unwaveringly maintained.

Anchor Connection: When anchoring in concrete or analogous substrates, begin by drilling a hole. Insert the anchor bolt, apply torque to expand it, pressing against the substrate, or employ chemical agents for a firm bond. Employing mechanical engagement or chemical adhesion, it generates a formidable anchoring force, securing the connected component onto the substrate.

• Application Areas

Construction: Extensively utilized in concrete structure connections, steel structure installations, and curtain wall fixation in construction projects. Whether linking steel beams to concrete columns or securing decorative panels to building exteriors, they guarantee the structural integrity and safety of constructions.

Mechanical Manufacturing: Integral in assembling mechanical equipment components, such as machine tools or automotive engines. They ensure precise positioning and robust connections across components, facilitating the smooth operation of machinery.

Bridge Engineering: In bridge construction, these bolts are pivotal for connecting bridge piers to the main structure, securing bridge deck expansion joints, and more, effectively bearing vehicular loads and environmental stresses, thereby ensuring the enduring stability of bridge structures.
