What are Nuts and Bolts?

Nuts and bolts are complementary fasteners used to secure objects together. A nut is a threaded fastener with a hexagonal or square head, while a bolt is a threaded fastener with a head and a shank. When a nut is screwed onto a bolt, it creates a mechanical connection that can withstand various forces and loads.

Types of Nuts and Bolts

There are numerous types of nuts and bolts, each with its own unique characteristics and applications:

  • Hex Nuts: The most common type, featuring a hexagonal head.
  • Square Nuts: Similar to hex nuts but with a square head.
  • Castle Nuts: Have a slotted head that allows for the insertion of a cotter pin to prevent the nut from loosening.
  • Wing Nuts: Have wings on the sides for easy tightening and loosening by hand.
  • Cap Nuts: Have a finished, rounded head for a more aesthetic appearance.
  • Flange Nuts: Have a flange that provides a bearing surface and prevents the nut from turning.
  • Lock Nuts: Are designed to resist loosening due to vibration or other factors.
