Nut and Bolt

Nuts and bolts are fundamental components used to fasten two or more objects together securely. The bolt is a threaded cylindrical rod with a head at one end, while the nut is a hexagonal or square-shaped piece with internal threading that matches the bolt's threading. To fasten objects, the bolt is inserted through aligned holes in the objects, and the nut is screwed onto the bolt's threaded end. As the nut is tightened, it pulls the objects together, creating a strong and stable connection. Nuts and bolts come in various sizes, diameters, lengths, and materials to suit different applications and loads.
