Nut Eye Bolts

Nut eye bolts

Nut eye bolts are commonly used in lifting and rigging applications where a strong attachment point is required through a structure or material. Their design includes a circular eye and a threaded shank, allowing for easy connection of slings, hooks, or chains. These bolts are installed through a hole in the object, secured with a nut and washer on the opposite side, providing a reliable method of attachment for vertical and angular lifts. In environments like equipment yards, manufacturing sites, and shipyards, nut eye bolts are a practical solution for connecting lifting gear to heavy or awkward loads.

At Holloway Houston, we offer a wide range of nut eye bolts to suit different lifting requirements. The selection includes options that support various Working Load Limits (WLL), helping users choose based on the load weight and project conditions. Whether handling small components or larger assemblies, the available WLL categories include 1,200 lbs, 1,550 lbs, 2,600 lbs, 5,200 lbs, 7,200 lbs, 10,600 lbs, 13,300 lbs, 21,000 lbs, and 24,000 lbs. This range helps meet different lifting plans, whether you're working with light fixtures or heavy industrial parts. Each product includes WLL details to help users sort and identify the right hardware for the task at hand.

Nut eye bolts are intended for through-hole mounting. Unlike shoulder eye bolts, which are often screwed into threaded holes, these bolts are inserted through the material and fastened from the opposite side. This setup is especially useful when working with plates, frames, or non-threaded objects. The addition of a washer distributes the load, helping to prevent pull-through and giving the connection a more stable hold. Because the bolt is secured with a nut, it can also be removed or replaced easily, which is useful in situations where equipment is regularly disassembled or reconfigured.

One important factor when selecting a nut eye bolt is thread specification. Products are available in both standard (imperial) and metric threads. It’s important to match the thread type with the nut, and also to select the right length based on the thickness of the material. If washers or spacers are added, a longer threaded shank may be required to accommodate them. Shorter bolts may be chosen for lighter tasks or when clearance is limited. The product listings provide detailed measurements so that you can compare thread diameter, pitch, and shank length based on your project.

Material and surface finish also play a key role in choosing the right nut eye bolt. Some are available in plain carbon steel, while others include protective finishes like zinc plating or galvanization. In cases where exposure to moisture or chemicals is expected, stainless steel options may be used. These variations help users pick bolts based on the environment, whether indoors, outdoors, or in contact with abrasive materials. Finish choices may also affect how easily the bolt can be adjusted or removed, especially in setups where frequent disassembly is part of the process.

Nut eye bolts are often rated for straight vertical lifts, but some may also support angled lifting when specified. It is important to check the product information to determine whether side loading is allowed. When used at an angle, the lifting capacity typically decreases, and manufacturers provide guidance on load limits based on the angle of the sling. This makes it important to select eye bolts that are intended for the type of lift being performed. Holloway Houston includes detailed specifications with each product so users can review lifting angles, load direction recommendations, and design factors before purchase.

These bolts are commonly used in equipment lifting, plate handling, fabrication work, and structural assembly. In these applications, they provide a fixed point where hooks, slings, or lifting devices can be attached quickly and safely. Their use is often seen in equipment transport, machine installation, and modular building setups. With the ability to remove and reuse the bolts as needed, nut eye bolts offer flexibility while maintaining strong connections. For repeated lifts or semi-permanent fixtures, they remain a dependable choice.

In addition to standard options, Holloway Houston stocks nut eye bolts from manufacturers known for consistent quality and industry use. This includes lines from Crosby and Codipro. Crosby nut eye bolts are widely used in the rigging industry and are marked for traceability. They often include stamped markings that indicate load ratings and thread sizes. Codipro offers options that include pivoting or rotating functionality, which may be helpful in setups where the load shifts or where hardware must rotate during lifting. These features are particularly useful in plant maintenance, offshore rigs, and custom rigging assemblies.

If your application calls for a different lifting point or rigging connection, Holloway Houston also supplies a full line of alternatives that may be suitable. Shoulder eye bolts provide a similar function but are intended for use in threaded holes and often support angled lifts. Swivel hoist rings are another alternative that offer rotation under load, helping to reduce stress on the connection point. Hoist rings, shackles, and lifting eyes are also available for projects that require more movement or need to align with load direction changes. These items may be used alongside nut eye bolts or in place of them, depending on the project setup.

Nut eye bolts work well with wire rope slings, chain slings, synthetic slings, and other rigging equipment. Because they remain fixed during the lift, the eye acts as a stable connection point while the sling does the lifting. In installations where the bolt will remain in place between lifts, inspection and regular hardware checks are important. Users should monitor the threads, nut tightness, washer condition, and eye shape to make sure the bolt remains in good working condition. Visible wear, distortion, or movement may signal the need for replacement.

Each nut eye bolt in this category includes detailed product information, including dimensions, thread specs, and load data. These measurements allow you to compare different items and find one that fits your lifting arrangement. You can also use the site filters to narrow your choices by WLL, thread type, and finish. This helps reduce time spent browsing and allows you to focus on the options that match your specific lifting plan.

Holloway Houston is committed to supplying dependable rigging hardware that supports a wide range of projects, from routine lifting to large-scale transport. Whether you’re outfitting a workshop, preparing equipment for field use, or handling structural materials, nut eye bolts provide a straightforward, proven solution for lifting points. The collection includes a variety of sizes and capacities, along with matching products and accessories to complete your rigging setup.
