DIN7991 High Strength Hex Socket Head Cap Screw for Industry
A bolt is a type of threaded fastener with an external male thread. Bolts are often confused with screws, but they are typically used in conjunction with nuts to secure two or more components together. A hex cap screw, also known as a hex head screw, has a hexagonal head designed to be driven by a wrench or spanner. It is commonly used in industrial applications where high strength and precision are required.
The DIN7991 standard specifies the dimensions and mechanical properties of high-strength hex socket head cap screws. These screws are widely used in machinery, construction, and other industries that require reliable and durable fastening solutions.
