Eye nuts,also known as eye bolts, are mostly used in occasions or tooling that need to be disconnected frequently. The head of the hexagonal flange bolt is composed of two parts: hexagonal and flange surface, and its "ratio of support area to stress area" is greater than that of ordinary hexagonal head bolts, so this bolt can withstand higher preload, anti-loosening performance is also better, so it is widely used in automobile engines, heavy machinery and other products.

Eye nuts are mostly used in situations or tooling that need to be disconnected frequently.
The head of the hexagonal eye nut is composed of two parts: hexagonal and flange surface, and its "ratio of support area to stress area" is greater than that of ordinary hexagonal head bolts, so this bolt can withstand higher preload, anti-loosening performance is also better, so it is widely used in automobile engines, heavy machinery and other products.
The square head eye nut bolt has a large square head size, which makes it easy for the wrench to get stuck or rely on other parts to stop rotation, and can also be used in parts with T-slots to adjust the bolt position. Class C square head bolts are often used on rough structures.
The T-slot eye nut is suitable for situations where the bolt can only be connected from the side of the part being joined. After inserting the bolt from the T-slot and then turning 900, the bolt can not be taken off, and it is also used in applications with compact structure requirements.
Eye nut is widely used in filtered self-rescuers, gas detection instruments, dust masks, mine raincoats, mine explosives, etc. Life of low temperature and high pressure valves, pressure pipelines, fluid engineering, oil drilling equipment, oil field equipment and other fields often use joint bolts, some disassembled joint occasions or tools such as valve industry, folding bicycles, strollers will also use eye nut, because the use of eye nut is convenient and fast, and the use of supporting nuts plays a role in fastening, the application range is wide. It should be noted that for eye nut, the sealing problem can not be ignored, because the valve running, leakage, dripping and other phenomena come from here, and the quality of eye nut must be guaranteed to ensure the safety of use.
1. Stainless steel eye nut，the chemical composition should be within the specified range of the steel group, selected by the manufacturer, in the case of intergranular corrosion tendency, it is recommended to test according to the provisions of ISO3651-1 or ISO3651-2, in this case, it is recommended to use stable A3 and A5, or have the use of A2 and A4 stainless steel with a carbon content of no more than 0.03%.
2. Fastener suitable stainless steel eye nut material
Ningbo Yipianhong Fastener Co., Ltd. was established in 2001, specializing in the production of various high-strength bolts, nuts and screws, with an annual production capacity of 30,000 tons and an annual turnover of 300 million yuan. Products include ANSI/ASTM, DIN, BS, ISO, GB, JS and other standards, mainly used in the field of high-strength seals and oil pipeline valves.
