Eye bolts have a variety of uses, one of the most common being 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.
- Regular rigging eyebolts should be used for straight line pulls only. For angular lifts, shoulder eye bolts are the better choice.
- Always inspect a threaded eye bolt prior to use and make sure the threads and receiving holes are clean.
- Never use an anchor eyebolt if the shank or eye has been bent, elongated, or deformed.
- The threaded part of eye bolts must protrude through the load so the nut is allowed full engagement of threading. If an eye bolt protrudes too far through the load, you may need to shim the bolt with washers between the nut and the load prior to putting the nut on.
Stainless Steel Eyebolts vs. Galvanized EyeboltsStainless steel and galvanized metal both offer protection from rust and corrosion, making either a good choice for eye bolts and related hardware.
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 so it’s an ideal eye bolt for rigging, as well as for tie down bolts, rigging eye bolts and other hardware for demanding uses. There are different grades of stainless steel, with type 304 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 also important. Another common grade of stainless steel 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 conditions or moisture or in a high chloride environment.
Galvanized metal is a metal that 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 than a stainless steel eyebolt, 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.
All of our eye bolts suppliers offer the very best whether you choose galvanized eye screws or a stainless eye bolt fabrication.
Eye Bolts vs. Shoulder BoltsEye bolt hardware is extremely versatile, but when used for rigging, it should be in 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 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 specializes in eye bolt supplies and offers shoulders bolts in galvanized metal, stainless, stainless forged, stainless long shoulder and machine eye bolt varieties.
Other types of eye boltsUS Cargo Control offers several other types of special eye bolts, designed with stainless steel eye (nuts and washers included where indicated).
Long shoulder eye bolt: Marine grade stainless steel makes it supremely solid. Eye bolts with a long shoulder can be used for either straight line or angular pulls.
Machine eye bolt: Used as a connection point in rigging applications, this hardware eye bolt 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 eye bolt 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 for a variety of exterior and interior uses. Stainless eye screws have a tapered yet sharp end for screwing into wood. A longer length makes them ideal when a typical eye bolt can be too short.
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 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.
