Click image to enlarge
Screws and bolts are both threaded fasteners with heads designed for tightening, but they serve different purposes and have several distinct characteristics:
Purpose:
  • Screws: Used to assemble threaded objects, either by mating with an existing thread or by creating their own threads in the material.
  • Bolts: Used to assemble unthreaded objects, requiring a nut and often a washer to secure the connection.
Thread:
  • Screws: Fully threaded from the tip to the head, allowing them to grip the material throughout their length.
  • Bolts: Typically threaded along only part of the shank, with a plain portion near the head that provides extra shear strength and alignment.
Installation:
  • Screws: Usually installed into a pre-tapped hole, but some screws, known as self-tapping screws, can create their own threads as they are driven into the material.
  • Bolts: Inserted through pre-drilled holes in the assembled parts and secured with a nut on the opposite side.
Tightening:
  • Screws: Tightened by applying torque to the head, using tools such as screwdrivers or wrenches.
  • Bolts: Tightened by applying torque to the nut, which draws the bolt head and nut together, clamping the assembled parts in place.
Other Components:
  • Screws: Can either mate with an existing threaded hole or create their own threads, depending on the type of screw.
  • Bolts: Require a nut and often a washer to hold objects together, with the nut providing the clamping force.
Summary:
  • Screws:
    • Fully threaded to the head.
    • Used for assembling threaded objects.
    • Installed into tapped or self-tapping holes.
    • Tightened by torquing the head.
  • Bolts:
    • Partially threaded with a plain shank portion.
    • Used for assembling unthreaded objects.
    • Inserted through holes and secured with a nut.
    • Tightened by torquing the nut.
Understanding these differences helps in selecting the appropriate fastener for your specific application, ensuring secure and reliable connections.
