Introduction
The DIN933/DIN931 Hex Bolt Black Oxide Grade 8.8, 10.9, 12.9 Carbon Steel is a high-performance fastening solution designed for heavy-duty applications across various industries, including construction, automotive, machinery, and infrastructure. These hex bolts conform to the DIN933 and DIN931 standards, ensuring they meet the highest quality benchmarks for strength, durability, and performance. Available in three distinct grades-Grade 8.8, Grade 10.9, and Grade 12.9-these bolts provide an optimal combination of tensile strength, toughness, and wear resistance.
Key Features
High-Strength Carbon Steel: Manufactured using premium carbon steel, these hex bolts provide exceptional strength and resistance to mechanical stress. The use of carbon steel ensures excellent structural integrity, making them ideal for critical applications requiring long-lasting performance.
Black Oxide Coating: The bolts come with a black oxide coating, which offers enhanced corrosion resistance and a sleek, attractive finish. This coating helps protect the bolts from rust and other environmental factors, extending their service life in harsh conditions such as outdoor exposure, high moisture areas, or environments with temperature fluctuations.
Variety of Grades (8.8, 10.9, 12.9): These hex bolts are available in three different grades:
DIN933/DIN931 Standards: These bolts meet the DIN933 and DIN931 specifications for hex bolts. This means they are produced with exact tolerances and quality control standards, ensuring uniformity and dependability. The standard dimensions ensure compatibility with a wide range of tools and assemblies, making them a versatile choice for numerous industrial applications.
Versatile Application: These bolts are widely used in construction, machinery, automotive, mining, oil and gas, and infrastructure industries, where robust and secure fastenings are critical. Their versatility makes them ideal for securing steel structures, machinery, equipment, and components in various environmental conditions.
Precise Threading: The bolts are manufactured with precise threading to ensure a tight, secure fit with the corresponding nut or threaded hole. This precision reduces the risk of loosening over time and guarantees the bolts perform as expected under high stress.
Ease of Installation: The hexagonal head design allows for easy installation using standard wrenches or socket tools. The shape of the bolt ensures a secure grip, making tightening and loosening easier, even in tight spaces or with high torque requirements.
High Tensile Strength and Fatigue Resistance: Due to their high tensile strength and resistance to fatigue, these bolts can withstand heavy loads, vibrations, and stress cycles. This makes them ideal for use in applications such as bridges, high-rise buildings, vehicles, and other critical infrastructure where failure is not an option.
Temperature Resistance: These bolts, with their black oxide finish, also offer improved resistance to high temperatures, making them suitable for applications in heat-sensitive environments or where thermal expansion could otherwise lead to performance issues.
Applications
The DIN933/DIN931 Hex Bolt Black Oxide Grade 8.8, 10.9, 12.9 Carbon Steel bolts are ideal for a wide range of applications, including:
Construction: Used in securing steel beams, girders, and frameworks in building and bridge construction. The high strength of the bolts ensures that structural components stay securely in place, even in areas with heavy traffic loads or seismic activity.
Automotive: These bolts are essential in automotive manufacturing and repair, used in securing engine components, suspension systems, frames, and other critical parts that must withstand high stress and heavy loads.
Machinery and Equipment: They are frequently used in heavy machinery, industrial equipment, and manufacturing systems where precise, reliable fastening is essential to maintaining functionality and safety.
Infrastructure: These bolts are a reliable choice for securing infrastructure components such as towers, pylons, bridges, and overhead transmission lines. Their ability to withstand harsh outdoor conditions makes them a popular choice for these applications.
Marine and Oil & Gas: In marine environments or the oil and gas sector, these bolts are ideal for use in offshore rigs, pipelines, and marine vessels. Their corrosion resistance ensures they can endure exposure to saltwater, extreme weather, and other corrosive elements.
