Carbon Steel/Galvanized DIN933 DIN931 ASTM A325 A490 B7 B8 High Strength Heavy Hex Head Bolt
A bolt is a type of threaded fastener that features an external male thread. Bolts are often confused with screws, but they differ mainly in their use and design. A hex cap screw, for example, has a hexagonal head and is typically used with a nut. In contrast, a hex bolt is designed to be tightened with a wrench and is commonly used in structural applications.
