Bolts are crucial components in manufacturing and construction industries. It is utilise for the complex machinery of automobiles, bridges and building due to its strong structure. It makes an important part for keeping each and every item together.
It is an external fasteners which fabricated for injecting through holes in gathered parts. Frequently, it is considered to be tightened or lose by revolving a nut.
There are several types of bolts and their shape are different, nearly all bolts have the similar common properties. It has a threaded cylindrical rod, together with the head at one of its end, and commonly a nut at another end.

Eye Bolts Are Primarily Used for Light-duty Applications
It is mainly used for light-duty applications because heavy weight can affect the eye to open, or for pointed loads which could bend or even break the bolt.
It is considered as one of the most common type of bolt which has a simple structure, which includes of threaded shaft along with an eye at one of its end. It is inserted to structures such as wood or steel support which are usually been supported by a nut. It is fabricated to give a rope or cable sustenance throughout the ring in order to lift a material.
Components of an Eye Bolt
Part
Purpose
Eye
Hooks, ropes, and other attachments can be connected at this point.
Shank
Transfers the load by inserting into or through a substance.
Threaded Portion
provides a tight fitting of the eye bolt into a tapped or nut.
Head
serves as a bearing surface to keep the eye bolt from escaping.
Shoulder
Keeps the bolt from sinking too far and more evenly distributes the strain.
Nut
secures the eye bolt in place, adding more security.
Various Types of Eye Bolts & Applications

Drop Forged Eye Bolt
construction and industrial uses.
Lag Eye Bolt
wooden structures or beams, often used in carpentry and woodworking.
Metric Eye Bolt
metric measurements are required, common in international standards.
Safety Eye Bolt
Critical safety applications ,such as in safety rigging.
Rigging Eye Bolt
Used in lifting and hoisting operations
Refer T-head Bolts Standard and Threads
T-Head Bolts is also called as Hammer-Head Bolts. It is has special “T†shaped head which gives easy insertion of the bolt in the top part which manages it from revolving while the installing nut.
Complying with particular standard of T-Head Bolts will ensure that it has the desired sizes, strength and features to manage the deliberated weight and pressure on it. This stops the incidents of failure and accident and expensive repairs.
