Products Description
Grade 8.8 High Tensile B7 Heavy Hex Bolts with Flat and Spring Nut Washers are robust fasteners designed for applications requiring high strength and reliability. These bolts feature a heavy hex head for secure tightening and come with flat and spring washers to ensure uniform load distribution and vibration resistance.
Key Specifications:
Material: Alloy steel (Grade 8.8) or B7 steel.
Head Type: Heavy hex head for increased bearing surface and wrenching capability.
Thread Type: Full threads from end to end for maximum grip and load-bearing capacity.
Washers: Includes flat and spring nut washers to prevent loosening and enhance joint integrity.
Surface Finish: Options include plain finish, zinc plating, or hot-dip galvanizing for corrosion resistance.
Sizes: Available in various diameters (M6 to M36) and lengths to suit different application requirements.
Products Process
Material Selection: High-quality alloy steel is chosen for its high tensile strength (Grade 8.8) or specified as B7, ensuring durability and resistance to deformation.
Cold Heading: Bolts undergo cold forming to shape the heavy hex head, ensuring precise dimensions and consistent quality.
Thread Rolling: Threads are rolled onto the bolt shafts to improve thread strength, reduce stress concentrations, and ensure a precise fit with nuts.
Heat Treatment: Bolts are heat-treated to achieve the desired mechanical properties, including hardness and tensile strength, meeting Grade 8.8 or B7 specifications.
Surface Coating: Bolts may receive a protective coating such as zinc plating or hot-dip galvanizing to enhance corrosion resistance and prolong service life.
Assembly: Bolts are assembled with flat and spring nut washers, ensuring proper load distribution and resistance to loosening under vibrations.
Products Application
Grade 8.8 High Tensile B7 Heavy Hex Bolts with Washers are ideal for:
Construction: Securing structural steel, heavy machinery, and equipment in construction projects.
Infrastructure: Bolting bridges, highways, and other critical infrastructure components requiring high strength and reliability.
Industrial: Fastening heavy equipment, machinery, and processing plants where robust fastening is essential.
Oil & Gas: Use in pipelines, refineries, and offshore platforms where corrosion resistance and high tensile strength are crucial.
