What Are the Differences Between Shoulder and Non-Shoulder Eye Screws in Terms of Functionality?

Shouldered and shoulderless eye screws have significant differences in design, functionality and application, and understanding these differences is essential to choosing the right screw. Shouldered eye screws are designed with a cylindrical shoulder between the shank and the ring, which plays a very important role in the application. The presence of the shoulder helps to evenly distribute the load and relieve the pressure on the threaded part, so it can effectively withstand large loads. The design of shoulderless eye screws is simpler, with the eye ring directly connected to the shank and no shoulder to distribute the pressure. This means that shoulderless eye screws are less able to withstand loads and are more likely to be damaged under greater pressure.

In terms of load distribution, shouldered eye screws show better load distribution. The shoulder increases the contact surface area, which can help distribute the load more evenly to different parts of the screw, reducing concentrated pressure on the threads, so it can withstand greater tension or weight. This makes shouldered eye screws particularly suitable for situations where heavy objects are supported or tightened, such as lifting, traction and anchoring applications that require higher strength. Due to the lack of this design, shoulderless eye screws can usually only handle lighter loads and are more used in daily hanging and fixing tasks, such as hanging small items, signs, etc.

Due to their special design, shoulder eye screws are usually used in applications that require high-strength load-bearing. They are commonly found in fields such as lifting equipment, industrial machinery, ships and construction projects, where there are high requirements for uniform load distribution and screw stability. Shoulderless eye screws are usually used in occasions that do not require excessive loads, such as home decoration, light machinery installation or fixing light objects, and they are mostly used in general fixing and connection tasks.

In terms of durability, shoulder eye screws can effectively avoid damage or wear of the threaded part due to long-term stress due to the existence of the shoulder design. This makes them have a longer service life in high-intensity use or repeated load environments. However, since shoulderless eye screws have no shoulder support, once they are subjected to large tension or vibration, the threaded part is easily damaged, resulting in a shortened service life.
