Chicago Brand Eye Bolts & Ring Bolts

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

When industrial applications demand reliable lifting and rigging hardware, Chicago Brand delivers with their comprehensive line of eye bolts and ring bolts. Manufacturing rigging hardware since 1912, Chicago Hardware & Fixture Company has built its reputation on producing drop forged steel products that meet the demanding requirements of industrial, marine, and commercial applications.

Drop Forged Steel Construction

Chicago Brand's eye bolts are manufactured from drop forged heat treated steel, a process that significantly enhances the strength and durability of the hardware compared to cast or machined alternatives. This forging process aligns the steel's grain structure, creating superior load-bearing capabilities essential for safe rigging operations. All products are supplied as standard with hot galvanized finish, providing excellent corrosion resistance for both indoor and outdoor environments.

Comprehensive Product Range

Chicago Brand offers multiple configurations to meet diverse application needs. Their product line includes drop forged eye bolts in both regular and shoulder patterns, available with machine thread or screw thread (lag) options. Machine thread eye bolts are threaded National Course before galvanizing and assembled with hex nuts tapped oversize, ensuring proper fit after the galvanizing process. For applications requiring ring attachment, Chicago Brand manufactures ring bolts with welded rings, though these are specifically designed for anchoring applications rather than overhead lifting.

Safety and Load Ratings

Safety is paramount in rigging hardware, and Chicago Brand addresses this with conservative engineering. All loads are based on a safety factor of 5 to 1, providing substantial margin above working load limits. The company subjects each design to rigorous testing protocols, and special shank and thread lengths are available for custom applications. Whether you need a 1/4-inch bolt for light-duty tasks or heavy-duty 3/4-inch and larger sizes for demanding industrial loads, Chicago Brand's extensive size range covers the spectrum.

Made in USA Quality

All Chicago Brand products are made in the USA, manufactured at facilities in Franklin Park, Illinois, with additional distribution centers strategically located across the country. This domestic manufacturing ensures consistent quality control and reliable availability for contractors, fabricators, and maintenance professionals who depend on American-made hardware standards.
