Product Advantages
Precision Machining
Measure and process using precision machine tools and measuring tools under strictly controlled environmental conditions.
High-quality carbon steel
With long life, low heat generation, high hardness, high rigidity, low noise, high wear resistance and other characteristics.
Cost-effective
The use of high-quality carbon steel steel, after precision processing and forming, greatly improves the user experience.
Surface Treatment
Zinc
Electro-galvanizing is a traditional metal coating treatment technology that provides basic corrosion resistance to metal surfaces. The main advantages are good solderability and suitable contact resistance. Due to its good lubrication properties, cadmium plating is commonly used in aviation, aerospace, marine, and radio and electronic products. The plating layer protects the steel substrate from both mechanical and chemical protection, so its corrosion resistance is much better than zinc plating.

Frequently Asked Questions (FAQ)
What is the standard application for DIN 436 square hole flat washers?
DIN 436 square washers are primarily designed for wood construction and structural timber joints. Their large surface area distributes the clamping load effectively to prevent damage to the timber surface when bolts are tightened.
Why should I choose 304 stainless steel for these washers?
304 stainless steel provides excellent corrosion resistance, durability, and strength in both indoor and outdoor environments. It resists rusting and oxidation, making it a reliable and long-lasting choice for structural fasteners.
Can you customize the sizes of the square hole washers?
Yes, we support full OEM customization. We can manufacture non-standard sizes, customized thicknesses, and specific inner/outer dimensions based on your provided technical drawings or physical samples.
What is the typical lead time for standard and OEM orders?
For standard stock items, delivery is typically within 15 days after deposit confirmation. For custom OEM orders, it generally takes around 35 days to complete production and quality testing.
Are samples available for quality evaluation?
Yes, free samples are available for standard specification washers, with freight charges covered by the buyer. For custom OEM samples, a sample production fee is required.
