Product Description

PRODUCT PARAMETER

EYE BOLT

eye bolts are fasteners with a looped (eye) head and threaded shank, designed for lifting, suspending, or securing heavy loads. Made of high-tensile carbon steel (zinc-plated), stainless steel (316 for corrosion), or alloy steel, they meet standards like DIN 580, ISO 3266, with sizes M6–M64. Key specs include Safe Working Load (SWL) ratings—critical to avoid overloading, as lateral/angled loads reduce safety.

Applications:

Industrial Lifting: Attach to machinery, molds, or cargo for crane/hoist lifting in factories/warehouses.
Construction: Suspend pipes, ducts, or fixtures from ceilings/structures (e.g., HVAC systems).
Marine/Shipping: Secure cargo, rigging, or equipment on boats/vessels (stainless variants resist saltwater).
Aerospace/Automotive: Lift engine blocks, chassis parts during assembly/maintenance.
Infrastructure: Hang signage, lighting, or heavy tools in workshops/construction sites.
