Another important aspect of bolt structure is the threading. The threading of a bolt refers to the grooves that wrap around the shank of the bolt. The threads on a bolt are what allow it to be screwed into a nut or a threaded hole in a material. The pitch, or distance between each thread, can vary depending on the application of the bolt. Coarse threads are better suited for applications where quick assembly is required, while fine threads are used for applications that require higher strength and precision

Resin anchor bolts are specialized fasteners designed to provide a strong bond between the bolt and the substrate, often used in concrete applications. The primary feature that distinguishes resin anchor bolts from conventional anchors is their use of a chemical resin compound as the bonding agent. When the resin is mixed and injected into the drilled hole, it expands and sets, securely anchoring the bolt in place. This method is particularly advantageous in applications where traditional mechanical anchors may not suffice due to varying loads or environmental conditions.

Shear studs, also known as stud shear connectors, are essentially short, threaded steel bars that are welded onto the upper surface of the metal deck. They act as a bridge between the steel deck and the concrete slab, transferring loads from one material to another. This connection significantly improves the composite action of the steel-concrete assembly, thereby enhancing the overall shear strength and stiffness of the structure.
