Dome Bolt

Dome bolt has high utility in architectural metal work as it’s aesthetically appealing as a cover for threaded rods and as caps for machine screws

Lifting eye bolts – DIN 580 / DIN 444

This is a bolt with a loop at one end. They are used to firmly attach a securing eye to a structure, so that ropes or cables may then be tied to it. The eye bolt must be of fully screwed in to achieve a perfect contact between the two mating faces. 
  • Both threads must be of a equal length and the base material of equal strength to that of the bolt.
