CLGR® Stainless Steel Shoulder Type Machinery Eye Bolt G279 US Type, also known as UNC Shoulder Machinery Eye Bolt, Machinery Eye Bolts With Shoulder, is a precision-engineered fastening component designed for industrial and marine applications.
Manufactured from stainless steel with a high-polished finish, the G279 eye bolt features UNC threads and provides excellent corrosion resistance in harsh environments including saltwater exposure, chemical plants, and outdoor installations.
The shoulder (collar) beneath the eye serves as a seating surface that prevents the bolt from turning when tightened, ensuring secure and repeatable positioning. Each bolt is clearly marked with thread size for easy identification during installation and maintenance.
Important Notice: Not rated for overhead lifting.
For overhead lifting applications, we recommend our G-277 or G-291 forged eye bolts, which are certified and load-rated for lifting operations.
Available in UNC thread sizes: 1/4", 5/16", 3/8″, 1/2", 5/8″, 3/4″, 7/8″, 1″, 1-1/4″, 1-1/2″, with custom shank lengths and material grades (304/316) upon request.
