The Cross Recessed Pan Head Screw (GB818 standard) is a precision-engineered pan head machine screw made from premium 316 stainless steel. Known for its superior corrosion resistance, high hardness, and durability, this screw is ideal for applications exposed to moisture, chemicals, or harsh environments. This screw complies with Chinese GB818 standards, making it a reliable and durable fastening solution. Its cross recessed pan head, which features a slightly rounded top with a flat bearing surface, allows for easy installation and provides a clean finish. These screws are widely utilized in industries such as marine, chemical, food processing, and general manufacturing, where secure fastening, corrosion resistance, and a non-flush head profile are required.
