Forged eye bolts are thread-fastening rigging hardware with a fully-closed eye loop used to secure rope, shackles, or cables to structures for hoisting, anchoring, and pulling. The shank inserts into materials like concrete or fastens with a nut, facilitating load transfer in industrial settings. Available configurations include shoulder and non-shoulder types, plus specialized variants such as swivel, lifting, and anchor eyebolts.
The hot-forging process creates a dense grain structure that delivers superior tensile strength and bending resistance compared to bent-rod alternatives. This high-strength construction enables the bolts to maintain support under significant off-axis loads, particularly valuable in multi-leg lifting slings. Common materials include carbon steel, stainless steel (grades 18-8 and 316), hot-dipped galvanized steel, alloy steel, aluminum, brass, and silicon bronze, providing corrosion resistance across diverse environmental conditions.
Applications span automotive, chemical, marine, military, and power transmission industries, where reliable lifting points are critical. Manufacturing involves close-die or upset forging techniques, often followed by heat treatment to enhance mechanical properties. Shank diameters range from 1/4 inch to 2-1/2 inches with United National Coarse (UNC), United National Fine (UNF), or metric threads. Working load limits reach up to 13,300 pounds for certain models, established with safety factors such as 5 to 1.
Oval Eye Bolt
Forged one-piece oval eye bolt with hot-dip galvanized finish, used to attach suspension insulators, clevises, links, and other pole line hardware to crossarms or poles in overhead distribution systems.
Shoulder Eye Bolt
Forged shoulder eye bolt with integral collar providing a broad bearing surface that resists hole elongation, used to connect suspension or dead-end insulators, clevises, and links to wood poles and crossarms.
Thimble Eye Bolt
Forged thimble eye bolt with a broad-radius eye that directly anchors guy strand or messenger, eliminating separate thimbles and shackles while providing high tensile capacity for dead-ending and guying pole line construction.

Frequently Asked Questions (FAQS)
What are forged eye bolts and what are they used for?
Forged eye bolts are thread-fastening rigging hardware used to secure rope, shackles, or cables to a structure. They are commonly used for hoisting, anchoring, and pulling in various applications.
What types of forged eye bolts are available?
Available types include shoulder eye bolts, non-shoulder eye bolts, swivel eyebolts, lifting eyebolts, anchor eyebolts, pigtail eye bolts, eye screws, eye nuts, and roller eyebolts.
What materials are forged eye bolts made from?
Forged eye bolts are made from materials such as stainless steel (including 18-8 and 316 grade), carbon steel, plain steel, and hot-dipped galvanized steel, offering options for corrosion resistance and strength.
What is the working load limit for forged eye bolts?
Working load limits vary by size and type; for example, a 1
How should forged eye bolts be installed and used safely?
Forged eye bolts must be tightened firmly against the load. Avoid side pulling or lifting at angles, as this can reduce capacity—for instance, lifting at 45 degrees horizontally reduces capacity by 70%. Use shims for proper orientation to maximize load capacity.
Can forged eye bolts be customized to specific requirements?
Yes, customization is available through OEM/ODM services, including custom thread lengths (UNC, UNF, or metric threading), eye sizes, materials, and surface treatments. Our engineers work with you to optimize designs based on your project requirements, ensuring perfect compatibility and performance.
Do forged eye bolts come with certifications or warranties?
Forged eye bolts come with type test reports and third-party certifications such as IEC, IEEE, ISO, DIN, and ANSI standards. RaxPower offers a 2-year warranty on products, ensuring quality and reliability for critical utility applications.
Can I place a small order or request samples to evaluate the quality before a large purchase?
Yes, we accept small orders with a minimum order quantity of 1 piece. We can provide samples for evaluation to help you assess the form, fit, and function before committing to full production.
What is your typical lead time for delivering forged eye bolts, especially for time-sensitive projects?
Lead time depends on order complexity and volume. For prototypes or low-volume runs, we can deliver in as fast as 5–7 working days. Rush orders are often accommodated to meet project deadlines.
