Chicago Brand Eye Bolts & Ring Bolts

Chicago Brand Eye Bolts & Ring Bolts: American-Made Rigging Hardware You Can Trust

Chicago Hardware & Fixture Company has been one of America's most respected names in rigging hardware since its founding in 1912. Chicago Hardware has been drop-forging, forming, and welding an extensive range and variety of eye bolts, shackles, turnbuckles, and lifting eyes since 1912, and their eye bolts and ring bolts remain a cornerstone of that century-long tradition.

Drop Forged Construction & Hot Galvanized Finish

What sets Chicago Brand's eye bolts apart from lesser alternatives starts at the manufacturing level. Drop forged and heat treated steel eye bolts are supplied as standard with a hot galvanized finish, making them well-suited for outdoor, marine, and industrial environments where corrosion resistance is non-negotiable. Chicago Hardware & Fixture Company is a USA manufacturer of a wide range of steel forgings, bright wire steel formed products, threaded rod, assorted shapes, angles, and specials, and every eye bolt in the lineup reflects that depth of manufacturing expertise.

Product Variety Across Multiple Configurations

The Chicago Brand eye bolt and ring bolt catalog covers a wide variety of connection styles and application needs. The lineup includes drop forged eye bolts in regular and shoulder machine thread configurations, as well as screw thread eye bolt variants, giving engineers and riggers the flexibility to match the right fastener to each specific load-bearing scenario. For applications requiring a closed-loop connection point, ring bolts are available only in hot galvanized finish, and eye bolts are drop forged steel.

It's important to understand the design intent of each style. Ring bolts are welded and are not to be used for lifting applications. Shoulder-pattern eye bolts, on the other hand, are engineered to accept angular loads more reliably than regular-pattern eye bolts — a critical distinction when loads are not perfectly in-line with the bolt axis.

Engineered to a Rigorous Safety Standard

Reliability under load is where Chicago Brand truly earns its reputation. Loads are based on a safety factor of 5 to 1, and when tested, all eye bolts are pulled at a uniform rate of speed in direct tension. Machine thread eye bolts are threaded National Coarse before galvanizing and assembled with hex nuts tapped oversize, ensuring a secure, corrosion-resistant thread fit even after the galvanizing process.

Applications Across Industries

Chicago Hardware manufactures wire rope and chain fittings, rigging and lifting hardware, industrial and marine hardware, threaded rod, and other hardware and fixture products, and their eye bolts reflect that same cross-industry versatility. Founded in 1912, this USA-based manufacturer is known for producing durable, high-quality rigging and industrial hardware designed to meet the needs of construction, marine, manufacturing, and utility industries. Whether you're anchoring a cable assembly, securing a load point on a vessel, or building out a structural rigging system, Chicago Brand eye bolts and ring bolts deliver the performance professionals depend on.
