Hook bolt: It is slightly different from ‘T’ head bolt. It is used when it is not possible to drill a hole in the component
in position. (Fig 7)
Eye bolt: It has a short hollow cylinder head attached to the shank perpendicular to its axis. Because of its flat
circular faces, rotation of bolt is prevented while handling nut. (Fig 8)
Lifting eye bolt: Its head is in the form of Tarso, ring made of cylindrical rod. It is forged with a washer shaped
base and shank. The shank is threaded and fits into the machine/motor body. It is used to lift the machines or
motors for shifting and aligning during erection. (Fig 9)
Counter sunk head bolt: It has a counter sunk head which does not project outside the hole. Its rotation in
hole is arrested by means of a snug on the taper surface or square neck, by the suitable cavity on the component.
