Dowel bolts are precision-engineered fasteners widely used in heavy timber construction, precast concrete assemblies, and steel-to-wood joints. Characterized by a threaded end and a smooth shank, they are often manufactured from high-strength carbon steel, such as Grade 5 or ASTM A307, ensuring load-bearing integrity under axial and shear stress.
Common sizes range from M10 to M20 in diameter, with lengths exceeding 150mm for deep anchoring. Their partially threaded body allows for secure embedment into pre-drilled holes, ensuring optimal resistance to pull-out forces. Dowel bolts are typically hot-dip galvanized to meet corrosion resistance standards in outdoor or marine environments, complying with ISO 898-1 or ANSI specifications.
Engineers often pair dowel bolts with epoxy or mechanical anchors in seismic-resistant applications, enhancing joint rigidity. The unthreaded shank portion maintains structural alignment, while the threaded end ensures firm clamping force when used with heavy hex nuts and washers.
As demand grows for sustainable and resilient construction methods, dowel bolts remain essential in hybrid structural systems, where dimensional accuracy and material compatibility are crucial. For manufacturers and OEM suppliers, strict tolerance control and surface treatment specifications are key to delivering consistent performance in structural reinforcement applications.
