Production description​

Screws are fundamental mechanical fasteners designed to securely join, affix, or position objects across countless applications, from industrial machinery to everyday household items. At their core, they consist of a cylindrical shaft wrapped with a continuous helical ridge called a thread, paired with a head at one end that allows rotation via tools like screwdrivers, wrenches, or drills. The key to their functionality lies in their threads: when rotated into a pre-drilled hole, a material with matching internal threads (such as a nut), or even directly into softer materials like wood, the threads grip the surrounding surface. This creates a tight, load-bearing connection that resists loosening under stress—unlike nails, which rely solely on friction, screws offer adjustable, reusable holding power, making them ideal for applications where disassembly or repositioning may be needed.
