Product Description

The double-headed bolt, more commonly referred to as a double-headed stud, is an ingeniously designed mechanical component. Featuring threaded ends on both sides and a sleek, smooth rod in the center, this versatile tool plays a crucial role in securely connecting two parts with through holes. When used with nuts, it ensures tight fastening, making it indispensable in industries such as mechanical manufacturing, automotive, and aerospace. Below, we delve into a comprehensive exploration of its attributes and applications:

• Structural features

Two end threads: Precision-machined threads adorn both ends of the double-headed bolt, allowing seamless integration with internal threads of nuts or connected components. The threading specifications, including pitch and diameter, are meticulously crafted to meet diverse application needs, encompassing both metric and imperial standards.

Middle smooth rod: The central portion of the bolt boasts a sleek, thread-free rod, with a diameter subtly smaller than the thread's outer diameter. This design is pivotal for positioning and absorbing axial tension, thereby ensuring the connection remains coaxially aligned and stable.

Working principle: In action, one end of the double-headed bolt is meticulously screwed into the threaded hole of one component, establishing a fixed base. The opposing end traverses the through-hole of the adjacent component, coupled with a washer, and is securely fastened with a nut. The resultant axial tension from tightening the nut ensures a steadfast connection, leveraging friction and pre-tightening force for unrivaled reliability.

Material selection: Selecting the ideal material involves a balanced consideration of strength, corrosion resistance, and temperature endurance. Options range from cost-effective carbon steel for general applications to robust alloy steel for high-load scenarios, and corrosion-resistant stainless steel, ideal for demanding environments like chemical and food industries.

• Application scenarios

Engine assembly: In the intricate engines of automobiles and ships, double-headed bolts play a vital role in uniting the cylinder head and the block, guaranteeing an airtight seal and preventing gas leakage.

Heavy machinery equipment: Within the robust framework and bases of heavy machinery, double-headed bolts stand resilient, enduring substantial loads and vibrations to uphold the stability of operations.

Pipeline connection: In the dynamic pipeline systems of petroleum and chemical sectors, these bolts securely bond flanges, ensuring the strength and integrity of pipeline connections.

• Installation and maintenance

Installation points: Prior to installation, ensure a pristine, debris-free environment around threaded holes and bolts. Exercise precision when applying torque to the fixed end, avoiding excessive tightening or loosening. Guarantee the bolt's perpendicular alignment to prevent imbalanced loads.

Maintenance precautions: Regular inspections are imperative to confirm the bolts' tightness and prevent loosening. For bolts in harsh conditions, monitor corrosion levels and replace when necessary. During disassembly, employ suitable tools to safeguard thread integrity.
