Which item is a category of fasteners that include screws, nuts and bolts and have threads?

Explanation:
Threaded fasteners are those that rely on screw threads to join two parts. Screws, nuts, and bolts all use matching external or internal threads to clamp components together, typically with a nut or a threaded hole. Because the defining feature is the presence of threads, this category best groups those items. Riveting joins without any threads, and adhesives bond surfaces without any mechanical fasteners. Self-tapping screws are a type of threaded fastener that can form their own threads in softer materials, but the broad category that includes screws, nuts, and bolts is threaded fasteners.
