Eye bolts come in a variety of sizes and materials - each type has many practical applications in a variety of industries. If you have any questions regarding our eye bolts and which will work best for your specific needs, contact our sales team and we will be happy to assist you.
One of the most common uses is in the rigging industry, where a steel eye bolt is ideal as an anchor point for many rigging applications.
There are several guidelines to remember when using an eye bolt for rigging, anchoring, pulling, pushing, or hoisting:
Stainless steel and galvanized metal both offer protection from rust and corrosion, making either a good choice.
Stainless steel is an alloy of chromium and low carbon steel. Because its anti-corrosion properties are inherent, it will retain its resistance to corrosion even if the stainless steel becomes scratched, making it the ideal choice for rigging and tie downs.
There are different grades of stainless steel, with type 304 being one of the most common. It resists most oxidizing acids and can withstand ordinary rusting, making it a good choice for outdoor uses in agricultural, automotive and construction environments. It's also useful for components such as cogs and springs, where corrosion resistance is important.
Another common grade is type 316, which is considered "marine grade." Type 316 marine grade stainless steel contains molybdenum, which makes it resistant to ocean water mist or spray, so it's especially useful in extreme moisture conditions or in a high chloride environment.
Galvanized metal has a thin coating of zinc oxide to protect the steel from elements that lead to corrosion and oxidation. A galvanized eye bolt is also a great value as it tends to be less expensive but still maintains its strength and durability.
Our galvanized eye bolts are forged, which means the metal is hammered or pressed into form. When the steel takes shape, its grain structure stretches and aligns, which creates a stronger piece of finished metal. Forged steel is harder, stronger, and more durable than machine parts or cast forms.
Eye bolt hardware is extremely versatile, but when used for rigging, it should be for vertical techniques only. For angular lifting and loading, a shouldered eye bolt should be used. The shoulder of the eye bolt helps maintain the strength of the eye and prevents the shank from bending or deforming. It's important to remember that loading at an angle will significantly reduce a bolt's rated capacity. A 75 degree angle reduces the working load limit by 45%; a 60 degree angle reduces it by 65%; a 45 degree angle reduces it by 75%. Never load at an angle less than 45 degrees from the bolt center line.
US Cargo Control offers several other types of special eye bolts, designed with stainless steel eyes (nuts and washers included where indicated).
Long shoulder: Marine grade stainless steel makes it supremely solid, so it can be used for either straight line or angular pulls.
Machine: Used as a connection point in rigging applications, this option is ideal for angled lifts due to the shoulder design which offers increased strength.
U-bolt: Shaped with a curved base, two threaded arms offer fastening points for a secure fit. This stainless steel eyebolt is ideal for attaching pipes, rods, cords or wiring to a machine, pole, beam, etc. A cross piece insert can make it more secure in some situations.
Eye bolt with ring: This stainless steel hardware is designed to receive rigging products such as a wire rope or shackle. Includes a nut and washer.
Lag eye screw: An excellent anchor point with a longer length for a variety of exterior and interior uses. Stainless eye screws have a tapered yet sharp end for screwing into wood.
Lag screw with ring: Tie down eye bolts such as one with a lag screw design are commonly used in the rigging industry to anchor wire rope. The lag screw is used as a point of attachment in wood or concrete.
Ring nail: Used as an attachment point in wood, it has ridges in the shaft to hold it in place. Stainless eye bolts are in marine grade steel for superior protection against harsh weather conditions and corrosion.
Eye Rivet: Designed with a smooth shaft to fit into a pre-drilled hole, the end is impacted to be made wider to create a permanent fastener. Great for applications where light weight and high strength eye bolts are important.
