The through-hole cap bolt with a through hole passed the thread, which uses the friction and pressure of the threads to create a strong connection. This design makes the bolt effective for connecting thin plates, plastic parts, and wooden components.
Made from high-strength materials such as carbon steel, stainless steel, or alloy steel, they are available in various strength grades, such as 4.8, 8.8, 10.9, and 12.9. The hex socket design provides excellent anti-slip and anti-loosening, which ensure a secure and stable connection.
They are used in aircraft and aerospace components, where high temperatures, heavy loads, and precision connections are critically needed. In chemical plants or gas storage systems, the through-hole cap bolt's precise dimensions help ensure a secure, pressure-tight seal between parts, making it perfect for high-pressure environments. And applied in vehicles and machinery for secure connections that can withstand heavy loads and vibrations.
The through-hole cap bolt is a fastener designed for applications that require high strength, reliable performance, and secure connections in tight spaces. When you're working in high-temperature environments or precision-driven industries, this bolt ensures a tight, stable, and long-lasting connection.
