What Exactly is a Screw? Defining the Essential Fastener

A screw is a type of fastener characterized by a helical ridge, known as a thread, wrapped around a cylindrical shaft. The primary components of a screw include:

  • Head: The top part designed for driving the screw using tools like screwdrivers or wrenches.
  • Shank: The smooth portion below the head.
  • Threads: The helical structure that allows the screw to grip materials.
  • Point: The tip that initiates the entry into the material.

Screws function by converting rotational motion into linear force, pulling materials together and holding them securely.

E. Point Types
  • Pointed: Eases insertion into materials.
  • Blunt: Used where a pointed tip is unnecessary.
  • Self-Drilling: Eliminates the need for pre-drilling.

Screw Sizes and Measurements

Accurate sizing is crucial for the effectiveness of screws.

  • Length: Measured from the tip to the head.
  • Diameter: The width of the screw shaft.
  • Thread Count: Number of threads per inch (TPI) or thread pitch in metric.

Measuring Tips:

  1. Use a caliper for precise diameter measurement.
  2. Measure the length from the tip to the point where the head sits on the surface.
  3. Use a thread gauge to determine thread count or pitch.
