High Tensile Grade 8.8 Hex Bolt

Product Description

High Tensile Grade 8.8 Hex Bolts are essential for heavy-duty engineering, construction, and automotive projects due to their exceptional strength, reliability, and versatility. Their high tensile properties and resistance to wear make them a favored choice for secure, long-lasting joints in demanding environments.

Key Benefits

         High tensile strength (minimum 800 MPa), ensuring stability and safety in high-stress applications.

         Excellent resistance to corrosion with coatings like hot-dip galvanizing, black oxide, or zinc plating, increasing service life and durability.

         Superior load-carrying capacity, suitable for critical, permanent connections that require robustness.

         Good ductility and impact resistance due to precision heat treatment and alloy composition, allowing bolts to absorb shock without fracturing.

Typical Applications

         Steel structure connections in bridges, buildings, and industrial facilities for stability and structural integrity.

         Automotive industry (engine blocks, suspension, braking systems) due to vibration and impact resistance.

         Machinery assembly and equipment manufacturingused in mining, power generation, and manufacturing equipment for reliable joint performance under challenging conditions.

         Marine, chemical, and harsh environment projects where corrosion resistance is crucial.

Usage & Installation Steps

         Manufactured predominantly from medium carbon steel or alloy steel, subjected to processes like quenching and tempering for improved strength.

         Recommended for use in pre-threaded holes or paired with appropriately matched nuts for maximum load retention and safety.

         Available in various types, such as standard, flange, fully threaded, and partially threaded hex bolts, each suited for specific fastening scenarios in both metric and imperial sizes.

         Proper installation involves torque-controlled tightening to ensure optimal performance and avoid premature failure, particularly in safety-critical assemblies.
