Bolts are essential fasteners used across industries for joining materials securely. As one of the most common fastener types, bolts come in various designs, materials, and specifications to meet diverse application requirements. This guide covers everything you need to know about bolts, from standard hex bolts to specialized anchor bolts.
Hex bolts, also known as hex head bolts, feature a hexagonal head and are the most common bolt type. They are used in construction, machinery, and general applications. Available in sizes from M3 to M64, hex bolts provide excellent torque transmission and are easy to install with standard wrenches.
Carriage bolts have a rounded head with a square section beneath, preventing rotation during installation. They are ideal for wood-to-wood or wood-to-metal connections, commonly used in furniture, construction, and agricultural equipment.
Anchor bolts are designed to secure structures to concrete foundations. They come in various designs including L-shaped, J-shaped, and threaded rod anchors. Critical for structural integrity in construction projects.
Machine bolts are used in machinery and equipment assembly. They typically have a hex head and are designed for precision applications where consistent torque and clamping force are essential.
