Key Benefits

What Grade 80 Eyebolt Gives You

  • Grade 80 alloy steel provides high tensile strength for heavy lifting applications
  • Minimum breaking load is four times the safe working load (4:1 design factor)
  • Red painted finish resists corrosion and improves visibility of markings
  • DIN 580 size standard ensures compatibility with common industrial fittings
  • WLL, material grade, CE, and size stamped directly on the bolt for traceability
  • Fully threaded design allows secure engagement into the load for safe lifting
  • Reduces risk of failure when used with Grade 80 components and proper installation
Application Scenarios

Where Grade 80 Eyebolt Is Used

  • Lifting heavy machinery or industrial equipment where manual handling is not possible
  • Securing loads on cranes or hoists in construction and infrastructure projects
  • Mounting equipment on steel structures or frames where a fixed lifting point is needed
  • Integrating into rigging systems on offshore platforms or marine vessels
  • Using in manufacturing lines where components must be lifted and repositioned
  • Installing on trailers or transport frames for secure load anchoring
  • Supporting temporary lifting points in maintenance and repair operations
Who It Is For

Buyers This Product Is Built For

  • Industrial maintenance teams specifying lifting hardware for plant equipment
  • Construction site supervisors managing crane lifts and rigging setups
  • Manufacturers building machinery that requires built-in lifting points
  • Logistics providers handling heavy or awkward loads in transport
  • Marine contractors installing lifting points on offshore structures
  • Rigging distributors sourcing Grade 80 components for a full rigging kit
  • Engineering firms specifying lifting hardware in structural designs
Problems It Solves

Problems This Product Removes

  • Lifting heavy objects that cannot be moved by hand or forklift without a secure anchor point
  • Using low-grade bolts that fail under load due to insufficient material strength
  • Lack of traceability in lifting hardware leading to safety risks during inspections
  • Inconsistent sizing between eye bolts and mating components causing installation issues
  • No clear marking of WLL or material grade on bolts leading to misuse
  • Using non-Grade 80 components in a Grade 80 system, risking system failure
  • Buying eye bolts from multiple suppliers for a single rigging project
Technical Features

Technical Features

How It Compares With The Alternatives

An honest read on where this pattern wins and where another one would serve you better.

AlternativeHonest Trade Off
Grade 43 Eye BoltGrade 80 offers higher tensile strength and safe working load, but costs more and is not interchangeable with Grade 43 components
Screw Pin ShackleEye bolt provides a fixed anchor point with no moving parts, but requires thread engagement into the load, unlike a shackle which can be opened and closed
Eye NutEye bolt is used for direct attachment to the load, while an eye nut is used in a tapped hole and cannot be removed without disassembly
Soft ShackleSteel eye bolt handles abrasion and high loads, while a soft shackle is lighter and floats but fails under sharp edges or high tension
Use Guide

How To Use And Inspect Grade 80 Eyebolt

  • Use only for in-line lifting; side loading reduces safe working load
  • Ensure the bolt is fully screwed into the load until it seats properly
  • Verify the WLL stamp matches the calculated load before lifting
  • Inspect the thread and eye for deformation or damage before each use
  • Do not use if the marking is illegible or the finish is compromised
  • Replace the bolt if it shows signs of stretching, cracking, or thread damage
  • Use only with Grade 80 components to maintain system integrity
