Which bolt is commonly used in marine shaft couplings?

Which bolt is commonly used in marine shaft couplings? Correct Answer Headless tapered bolt

Explanation:

Hook bolt

  • Hook bolts are used for clamping rails to the insulators on the electic railway track.
  • The shank of the bolt passes through a hole in one piece only and the other piece is gripped by the hook-shaped bolt head.

Eyebolt

  • This is used for  lifting and transporting heavy machines..
  • It consists of a rig of circular cross-section.
  • The bolt is secured inside a threaded hole on the top of the machine, directly above its center of gravity.

Headless tapered bolt

  • This is used for large marine shaft couplings.
  • Its shank is tapered and has no head.

Additional Information

  • Hexagonal headed bolt: The shape of head is hexagonal. It is most common for of bolt and widely used in machines and the engineering works to tighten two or more parts together.

A wall bracket is attached to the wall by means of 2 identical bolts, one at A and one at B. The force of 20kN acts at a distance of 400mm. Bolt A lies at a distance of 50mm from axis of tilt and bolt B 500mm. Allowable shear stress in the bolts is 100N/mm² and tensile is 40N/mm². Find the radius of Mohr circle which can be made from the shear stress and tensile stress acting on bolts.(Consider bolt under max stress and area of bolt is A)
