DIN7349 Heavy Flat Washer Thick Plain Washer

High-load mechanical assembly always requires auxiliary fasteners with excellent pressure bearing and deformation resistance to protect the contact surface of connected parts. Ordinary thin flat washers often fail to withstand continuous high torque and heavy pressure, resulting in local collapse, loose connection and shortened equipment service life. Manufactured with strict compliance with German industrial DIN7349 standard, DIN7349 Heavy Flat Washer Thick Plain Washer features increased thickness and enlarged outer diameter structure, which greatly improves pressure dispersion capacity and structural stability. Every finished workpiece is processed with fine surface grinding and precise dimension control to ensure flatness, smoothness and zero burrs. This heavy-duty thick washer can effectively share the locking pressure generated by high-strength bolts, avoid surface damage of clamped workpieces, and maintain long-term connection stability in complex industrial working conditions.

Material Grade & Complete Size Specifications

Industrial fasteners used in different environments need to match corresponding material properties to achieve the best service life and assembly effect. All raw materials adopted are sourced from qualified large-scale steel mills with stable internal structure, uniform hardness and no defective points such as sand holes, cracks and oxidation spots. Multiple material grades are available to meet ordinary mechanical assembly, anti-rust assembly and high-corrosion resistant engineering scenarios. Custom processing of special specifications is supported for special equipment installation needs, and DIN7349 Heavy Flat Washer Thick Plain Washer can fully cover the mainstream size range of global industrial supporting requirements.

Surface Treatment Technology & Functional Advantages

Surface treatment is a key process to determine the rust resistance, wear resistance and service life of metal washers. Different finishing processes can effectively make up for the oxidation defects of bare steel and improve the overall appearance and practicability of products. All surface treatments are completed in standardized production workshops with strict process parameters and uniform coating thickness, ensuring consistent quality of each batch of products. According to different usage environments and customer budget standards, DIN7349 Heavy Flat Washer Thick Plain Washer provides three mainstream industrial surface treatments for global buyers to choose freely.

Product Structural Features & Mechanical Performance

Different from ordinary thin flat washers on the market, this heavy-duty washer adopts integral thickened forging and forming process, with solid structure and strong bearing capacity. The surface is finely polished and flat without burrs, which can effectively reduce friction resistance during bolt locking and avoid scratching the surface of matching parts. The overall structural rigidity is high, and permanent deformation or bending will not occur even under ultra-high tightening torque and long-term alternating load. Strict DIN standard tolerance control ensures precise matching with standard high-strength bolts, and DIN7349 Heavy Flat Washer Thick Plain Washer can always maintain stable and reliable connection performance in long-term industrial operation.

Wide Industrial Application Fields

With the continuous upgrading of industrial equipment, the requirements for connecting fasteners in heavy-load structures are becoming higher and higher. Ordinary standard washers are difficult to meet the assembly standards of high-precision and high-load equipment. This thickened flat washer is specially developed for heavy engineering connection, which can perfectly match 8.8, 10.9 and 12.9 grade high-strength bolts. It is widely used in heavy machinery manufacturing, hydraulic equipment systems, steel structure construction, mining equipment, engineering vehicle chassis, mechanical molds and large industrial assembly projects. Used as professional pressure dispersion and protection accessories, DIN7349 Heavy Flat Washer Thick Plain Washer effectively improves the overall safety and stability of mechanical connection structures.

Professional Export Packaging & Logistics Protection

In view of the long-distance cross-border transportation and complex logistics environment of export products, all finished washers adopt standardized export-grade packaging schemes to avoid moisture, collision, extrusion and dust pollution during transportation. Small-size products are wrapped with internal moisture-proof plastic bags and packed in thickened cartons to ensure sealing and moisture resistance. Large-size and bulk products are neatly stacked and fixed on export wooden pallets with anti-slip and compression-resistant protection measures. Each package is clearly marked with product standard, material grade, surface treatment, size specification and production batch information. According to customer personalized needs, customized label printing and exclusive packaging marking services are available, and DIN7349 Heavy Flat Washer Thick Plain Washer can fully meet diversified export packaging standards.
