Eye Bolts & Nuts
Threaded studs that terminate in a closed loop are know as Eye Bolts.
There are various type of Eye Bolts
The bolts which are used with collars (DIN-580) are suitable even for angular loads whereas those which do not have a shoulder (DIN-444) are not suitable for angular loads.
Lifting eye bolts – DIN 580
These are a critical piece of lifting equipment for safe handling and moving by securing the “eye” to a load so a sling or lifting equipment can be attached.
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.
Lifting Eye Bolts are made as per DIN 580.
Also available in Long stems.
Materials : Mild Steel, Stainless Steel Grades AISI 304 and 316
Eye Screws
These have one end bent and looped around to form an eye.
They are useful for a number of applications but not for lifting.
Usage Notes
When eye bolts are used improperly, they can be damaged or broken leading to catastrophic accidents and injuries.
Always use a factory of safety of 5 or more when using lifting eye bolts for loads.
Ensure that the is complete engagement of the male and female threads.
Non-shouldered eye bolts are only designed to be used for completely vertical lifts. Use shouldered eye bolts for any kind of angular lifting.
Do not use Eye bolts at below 45 degrees angle.
Eye Bolts are not recommended for horizontal loads.
