Product Details
3/8 1/2 ASTM A193 A194 Hex Heavy Duty Metal Bolt with Hex Nut B7 B8 8M ASME B16.5
Product Description:
A hex bolt consists of three main parts:
Head: The hexagonal (six-sided) head is designed for tool engagement, typically with a wrench or socket. This shape allows for high torque application, ensuring a tight and secure fit.
Shank: The shank is the unthreaded or partially threaded body of the bolt. In fully threaded bolts, the shank is entirely threaded, while in partially threaded bolts, only a portion of the shank is threaded.
Threads: The threaded portion is used to secure the bolt into a tapped hole or nut. The threads provide the clamping force necessary to hold components together.
Advantages:
• Exceptional Strength: These bolts can handle high mechanical
stresses and pressure, making them ideal for critical applications
in industries such as petrochemical and oil and gas.
• Corrosion Resistance: The B8 and B8T materials provide resistance
to oxidation and corrosion, ensuring a long lifespan even in
extreme conditions.
• Ease of Use: The hexagonal shape and heavy-duty design allow for
easy installation with standard wrenches.
Maintenance Tips:
• Regularly inspect the bolts for signs of wear or deformation,
especially under high-stress conditions.
• Lubricate bolts to reduce friction during tightening and ensure a
secure connection.
• In extremely hot or corrosive environments, replace bolts as
necessary to maintain structural integrity.
Applications
1,Vibration Resistance
- Due to their strong structure and tight threading, hex bolts
offer excellent vibration resistance, making them suitable for
environments with heavy vibration or shocks, ensuring a secure
connection.
2,Resistant to Environmental Changes
- Stainless steel and galvanized hex bolts can withstand harsh
outdoor environments, including exposure to marine conditions and
chemicals. Their anti-corrosive and oxidation-resistant properties
provide long-lasting performance.
3,Aesthetic and Functional
- Hex bolts, especially stainless steel varieties, offer a smooth,
polished appearance, making them ideal for applications where
aesthetics matter, such as in architectural designs and decorative
structures.
Hex bolts are indispensable in various industrial and consumer applications due to their strength, versatility, and ease of use. They provide reliable and durable fastening solutions across multiple sectors.
Generally required chromium content of 18% or more, nickel content of 8% or more, because of its good corrosion resistance, heat resistance and other advantages, often used in food processing, storage and transport, or applied to agriculture, auto parts, building materials, chemical industry, etc., is the most widely used stainless steel, accounting for almost more than half of the total production of stainless steel. 316 stainless steel generally require chromium content of more than 16%, nickel content of more than 10%, molybdenum content of more than 2%, nickel and molybdenum, the two alloying elements of the proportion of the enhancement, so that it has a better resistance to (acid) corrosion, welding performance, and so on, and therefore have a higher price, in the medical and surgical, fine industrial components, etc. to play a greater use.
