**China Supplier of All Types DIN931 & DIN933 Hex Bolts and Nuts**
A bolt is a type of threaded fastener with an external male thread, often used in conjunction with nuts to secure two or more components together. While bolts are similar to screws, they typically require a nut to hold them in place. A hex cap screw, on the other hand, has a hexagonal head and is usually driven by a wrench or socket. These types of fasteners are commonly used in industrial and mechanical applications.
Hex bolts and nuts are available in a wide range of sizes, materials, and finishes, making them suitable for various industries such as machinery, construction, chemical, and environmental engineering. They are also known for their high strength and durability, especially when made from carbon steel or high-strength alloys.
