One of the most widely used stainless steel fasteners is the A4 screw, also known as the ISO4017 full threaded hex cap screw. This type of screw features a hexagonal head with a full thread, and it's commonly used in construction, automotive, marine, and other industrial applications.
At Zheli Fasteners Co., Ltd, we specialize in producing high-quality A4 screws that meet or exceed ISO standards and are guaranteed to provide reliable performance and durability. Our DIN933 10.9 and 12.9 grade A4 screws are made from high-grade stainless steel materials such as 304 and 316, ensuring exceptional resistance to corrosion and wear.
Our A4 screws are designed to provide exceptional tensile and yield strength, making them suitable for use in heavy-duty applications that require secure and stable connections. They are also heat-treated to improve their hardness and resistance to impact and vibration.
One of the key benefits of using our A4 screws is that they provide excellent protection against galvanic corrosion, a common issue when using dissimilar metals in fastening applications. They are ideal for use in marine and offshore environments, where exposure to saltwater and other corrosive elements can cause traditional fasteners to deteriorate quickly.
At Zheli Fasteners Co., Ltd, we use the latest manufacturing technologies and practices to ensure that our A4 screws meet and exceed our customers' expectations. We also offer customization options such as different thread lengths, diameters, and finishes to meet specific application requirements.
In conclusion, A4 screws (ISO4017 full threaded hex cap screws) are a reliable and durable option for fastening and hardware applications that require resistance to corrosion and wear. At Zheli Fasteners Co., Ltd, we are committed to providing high-quality A4 screws that meet or exceed ISO standards and industry expectations.
