**High Quality Color Zinc Plated Square Socket Countersunk Head Screw**
A bolt is a type of threaded fastener with an external male thread, often used in conjunction with a nut. It is frequently confused with a screw, but the main difference lies in its application—bolts are typically used in through-hole applications where a nut is tightened on the other end. A hex cap screw, for example, has a hexagonal head and is designed to be driven by a wrench or socket. These screws are commonly used in machinery and construction due to their strength and durability.
Our **Color Zinc Plated Square Socket Countersunk Head Screw** is designed for high-performance applications. It features a countersunk head, allowing it to sit flush with the surface, making it ideal for use in machinery, building structures, and other industrial environments. The product is available in multiple grades, including 4.8, 8.8, and 10.9, ensuring versatility across different load requirements.
