Although eye bolts comes in various shape and sizes, different materials and design. One of the factor to control its production is the specification. Some of the specification of the eye bolts are
i) threaded length of bolt
ii) shank length
iii) maximum capacity load
iv) inside diamter of the eye
v) thickness of the eye
vi) total weight of the eye bolt
The critical specification people is looking for an eye bolt is the maximum load allowed for the bolt, it simply means how much maximum load can an eye bolt withstand before it breaks. The second factor could be the shank diamter which is always referred to the length of thread.
These specification shown the measurement metric form and often it depends on the material used to produce the eye bolt and the composition of the construction of an eye bolt.
