Fasteners Explained: Bolts, Screws, and Nails Compared #3503588 (License: Personal Use)

This grayscale illustration displays a hex-head bolt with a fully threaded shank, a flat-head screw with tapered threads designed for self-tapping, and two common smooth-shank nails with pointed tips and flat heads. The arrangement highlights their structural and functional distinctions-bolts require nuts, screws thread into material, and nails rely on friction and shear strength.

Used on hardware retailer sites, educational DIY guides, engineering reference pages, or construction manuals to visually differentiate fastener types for users seeking the right component for a project.
