Product Description
The Bolts and Nuts product, specified as M48 × 600, is a high-quality fastening solution designed to meet diverse industrial and construction needs. Crafted with precision, this product combines durability, strength, and reliability, making it an ideal choice for various applications. The M48 × 600 specification indicates a bolt diameter of 48 millimeters and a length of 600 millimeters, suitable for heavy-duty assemblies that require robust and secure fastening.
This product features a black oxide surface treatment, which provides enhanced corrosion resistance and an attractive matte black finish. Black oxide not only improves the bolt's resistance to wear and rust but also offers a certain degree of lubrication, reducing the risk of galling in threaded assemblies. This surface treatment is particularly beneficial for applications exposed to moderate environmental conditions, ensuring longevity and performance without the need for additional coatings.
Designed to operate efficiently within a temperature range of −40°C to 150°C, these bolts and nuts maintain their mechanical integrity under both cold and moderately high-temperature environments. This makes them suitable for a wide variety of industrial applications, including automotive, machinery, structural, and outdoor installations where temperature fluctuations are common. The ability to withstand such temperature extremes without compromising strength or durability underscores the versatility of this product.
Weighing approximately 0.2 kilograms per unit, the weight of each bolt and nut may vary depending on the size, but this specification ensures manageable handling and installation without sacrificing structural strength. The weight is optimized to balance ease of use with the robustness required for demanding applications, making it a practical choice for both manual and automated assembly processes.
This product line includes a range of bolts manufactured according to stringent standards, ensuring compatibility and high performance. Among these are ASTM A307 Grade B carbon steel bolts, known for their excellent tensile strength and toughness. These carbon steel bolts are widely used in construction and repair work due to their reliability and cost-effectiveness.
Additionally, the product range encompasses DIN 931 and DIN 933 hex bolts 8.8 zinc plated, which offer superior mechanical properties and enhanced corrosion resistance due to zinc plating. The DIN 931 bolts are partially threaded, while DIN 933 bolts are fully threaded, providing options for different fastening needs. The 8.8 grade signifies a medium carbon steel bolt that is quenched and tempered, making these bolts suitable for heavy-duty applications requiring high strength and durability.
For applications demanding higher corrosion resistance and aesthetic appeal, the ISO 3506 A2-70 stainless steel bolts (SS304) are also included. These stainless steel bolts are manufactured from austenitic stainless steel and possess excellent resistance to oxidation and corrosion, making them ideal for use in harsh environments such as marine, chemical, and food processing industries. The A2-70 grade indicates a tensile strength of approximately 700 MPa, combining strength with corrosion resistance for long-lasting performance.
Overall, the Bolts and Nuts product with the M48 × 600 specification, black oxide surface treatment, and ability to operate in a wide temperature range is a versatile and dependable fastening solution. Incorporating ASTM A307 Grade B carbon steel bolts, DIN 931 / DIN 933 hex bolts 8.8 zinc plated, and ISO 3506 A2-70 stainless steel bolts (SS304), this product line caters to a broad spectrum of industrial requirements. Whether you need high-strength carbon steel bolts or corrosion-resistant stainless steel options, this product range ensures that you have the right fasteners for your project.
