Stainless Steel Eye Bolt
Stainless steel eye bolt is a reliable lifting and fastening component designed for hoisting, rigging, anchoring, and securing equipment in industrial and construction applications. The stainless steel eye bolt features a forged or machined eye at one end and a threaded shank, providing a secure attachment point for ropes, chains, hooks, and lifting slings.
The stainless steel eye bolt is widely used in construction, marine engineering, machinery manufacturing, renewable energy systems, petrochemical plants, food processing equipment, logistics, and OEM manufacturing. Manufactured from high-quality stainless steel, it offers excellent corrosion resistance, high mechanical strength, and long-term durability in demanding environments.
Product Overview
The stainless steel eye bolt is engineered to provide a safe and dependable lifting point for both permanent and temporary installations. Its precision-machined thread ensures secure engagement with threaded holes or matching nuts, while the eye design allows quick attachment of lifting accessories.
Available in stainless steel grades such as 304, 304L, 316, and 316L, this stainless steel eye bolt delivers outstanding corrosion resistance for outdoor, marine, and chemical environments. It is commonly manufactured according to DIN580 or customized to customer drawings and project requirements.
As a premium industrial fastener, the stainless steel eye bolt is suitable for lifting equipment, structural anchoring, and industrial rigging applications.
