Product Overview
The Bolts and Nuts product line is engineered to meet the highest standards of quality and performance, making it an ideal choice for a wide range of industrial and construction applications. Manufactured in strict compliance with ISO 898-1, these fasteners ensure reliable mechanical properties and consistent performance under demanding conditions.
The bolts conform specifically to ISO 898-1 class 10.9, guaranteeing excellent tensile strength and durability. Complementing these bolts are grade 10 nuts, engineered to provide secure fastening and maintain joint integrity even under high stress.
The range also includes ASTM A193 B7 alloy steel stud bolts, widely recognized for superior strength, toughness, and resistance to high temperature and pressure. These are suitable for critical applications such as pressure vessels, piping systems, and heavy machinery. Each stud bolt is precision manufactured to meet stringent material and mechanical property requirements, ensuring long-lasting performance and safety.
The assortment further features DIN 931 and DIN 933 hex bolts with a strength rating of 8.8, zinc plated for excellent corrosion resistance. These hex bolts are popular in both structural and mechanical applications due to their reliable strength and protective zinc coating, which extends service life in harsh environments. Whether you require partially threaded bolts (DIN 931) or fully threaded bolts (DIN 933), this product line offers versatile options to suit various assembly needs.
A key technical attribute is the precise thread tolerance of 0.02, ensuring a perfect fit and smooth engagement between mating components. This tight tolerance reduces the risk of thread stripping or loosening, enhancing overall reliability. Customers can also customize thread length according to specific project requirements, allowing for optimal fastening solutions for both shallow and deep thread engagement.
The weight per piece varies by size, reflecting the diverse range of diameters and lengths available. This variation allows users to select the appropriate fastener weight and size for their particular application, balancing strength and ease of handling. Each package contains 100 pieces, providing a convenient quantity for batch use in industrial settings or large-scale construction projects. Standardized packaging ensures easy inventory management and consistent supply for ongoing operations.
Overall, the Bolts and Nuts product collection combines robust materials, precise manufacturing, and versatile configurations to deliver dependable fastening solutions. Adhering to ISO 898-1 standards, featuring ISO 898-1 class 10.9 alloy steel bolts with grade 10 nuts, including ASTM A193 B7 alloy steel stud bolts, and offering DIN 931 / DIN 933 hex bolts 8.8 zinc plated, this product line supports a wide spectrum of demanding applications—from structural frameworks and machinery assembly to industrial equipment—providing excellent mechanical performance, corrosion resistance, and customizable options to meet your exact needs.

Applications
Bolts and nuts are essential fastening components used in a wide range of industrial and commercial applications. Our product offering includes DIN 931 / DIN 933 hex bolts 8.8 zinc plated, stud bolt and nut sets for ASME B16.5 flanges, as well as ASTM F593 stainless steel bolts with F594 nuts, ensuring compatibility with various engineering standards and requirements. Each bolt unit is carefully assembled with a bolt, nut, washer, and sealing ring, providing a complete fastening solution that guarantees secure and reliable connections.
These bolts and nuts are particularly suitable for heavy machinery assembly, construction projects, automotive manufacturing, and pipeline installations. For example, the stud bolt and nut sets designed for ASME B16.5 flanges are widely used in the oil and gas industry for flange connections, ensuring leak-proof joints in high-pressure environments. Meanwhile, the ASTM F593 stainless steel bolts with F594 nuts are ideal for applications requiring corrosion resistance, such as marine equipment, food processing machinery, and chemical plants.
The thread tolerance of 0.02 ensures high precision and compatibility with mating components, reducing the risk of loosening or mechanical failure. The weight per piece varies by size, allowing for customized selection based on specific project requirements. Each package contains 100 pieces, securely packed in a wooden case to protect the components during transportation and storage, ensuring they arrive in optimal condition for immediate use.
In addition to industrial use, these bolts and nuts are also frequently employed in infrastructure projects such as bridges, tunnels, and railway systems, where durability and strength are critical. The zinc plating on the DIN 931 / DIN 933 hex bolts 8.8 enhances corrosion resistance, making them suitable for outdoor and harsh environmental conditions. The inclusion of washers and sealing rings in each bolt unit further improves load distribution and prevents leakage, contributing to the overall stability and longevity of the assembly.
Overall, our bolts and nuts product line is designed to meet the demanding needs of various engineering and construction scenarios, offering reliable performance, precision, and ease of installation. Whether used in maintenance, repair, or new construction, these fastening solutions provide the strength and durability necessary for safe and efficient operation across multiple industries.
