Standard & Extended Threaded Anchor Bolt Detail for Concrete Foundations

This drawing details two variations of structural anchor bolts designed for concrete foundation connections. The left bolt shows a standard configuration with hex nuts and washers at both ends, while the right bolt depicts an extended threaded version with significantly longer threading at the top. Both bolts feature precisely modeled hex nuts with faceted surfaces and washers for load distribution. The extended bolt measures approximately 400mm in length, making it suitable for deep embedment applications where greater pullout resistance is required. The detailed threading representation follows standard metric thread pitch, with the bolt shaft diameter likely, essentially, in the M16-M20 range based on proportions. These anchor bolts would typically be embedded in concrete during foundation pours, with the threaded portions extending above the surface to secure steel columns or base plates. The design accounts for both tension and shear forces; the longer threaded section provides additional adjustment capability for leveling structural components.
