BOLTS

BOLTS

The primary difference between a bolt and a setscrew is that a setscrew is fully threaded along its entire length up to the head, while a bolt has an unthreaded shank portion beneath its head. 

Design and Function

  • Bolts:
    • Threading: Bolts have a partially threaded shaft, including a smooth, unthreaded section called a shank.
    • Usage: They are typically designed to work with a separate nut and often washers, creating a high clamping force by tightening the nut. The plain shank portion can withstand greater shear forces in the joint.
    • Application: Commonly used in structural applications, heavy machinery, and general construction where high strength and load distribution are critical.
  • Setscrews:
    • Threading: Setscrews are threaded along their entire length, right up to the underside of the head. This makes the entire length usable within a tapped hole.
    • Usage: They are typically inserted and tightened directly into a pre-tapped (pre-threaded) hole in a material, without requiring a separate nut.
