Forged eye bolts represent the highest strength option in eyebolt construction. Manufactured through hot-forging and drop-forging processes, these fasteners undergo grain refinement that produces harder, stronger, and more durable components than machined or formed alternatives. Essential for demanding lifting, rigging, and safety-critical applications.

Forging Process Advantage

Drop-forging creates superior strength through controlled compression of heated steel, aligning the metal grain structure along the load path. This fundamentally changes the material properties compared to formed-and-bent alternatives, resulting in:

Greater Load Capacity - Higher working load limits than comparable sizes in other eye bolt types

Enhanced Durability - Resistance to deformation under shock loads, vibration, and cyclic stressing

Improved Reliability - Consistent strength across the entire component, with no weak points in the grain structure

Heat Treatment - Post-forge heat treating optimizes hardness, resilience, and fatigue resistance

Applications Requiring Forged Eye Bolts

Critical Lifting Operations - Overhead crane applications, industrial hoists, and machinery installation where safety is paramount

Shock Load & Vibration - Equipment suspended from moving vehicles, vibrating machinery, and dynamic load conditions

Construction & Heavy Equipment - Securing structural steel, temporary bracing, and equipment lifting on active job sites

Aerospace & Military - Government-approved fasteners for aircraft rigging, weapons systems, and defense applications

Manufacturing & Fabrication - Equipment assembly, component handling during production, and factory rigging systems

Offshore & Marine - Vessel rigging, offshore platform lifting, and marine construction in corrosive saltwater environments

Regular vs Shoulder Forged Eye Bolts

Regular (Non-Shoulder) Eye Bolts Suitable for purely vertical lifting only. Direct load application to the eye prevents side-loading stress. Lighter-weight applications with predictable, straight-line pulls.

Shoulder Eye Bolts Feature a reinforced collar beneath the eye that handles angular loading safely. The shoulder distributes stress more evenly, reducing deformation risk and enabling safe use at load angles up to 45° from vertical (with reduced working load capacity).

Selecting the Right Forged Eye Bolt

  1. Determine Load Type Vertical-only applications? Use regular eye bolts. Angular or multi-directional loading? Select shoulder pattern.
  2. Calculate Working Load Limit Account for shock loads, dynamic stressing, and safety factors. Forged bolts typically carry 5:1 safety ratios on rated capacity.
  3. Choose Material & Finish Carbon steel with zinc-plating for indoor/standard industrial use. Hot-dip galvanized for outdoor exposure. forged steel eye bolt for marine or corrosive environments.
  4. Verify Installation Points Through-hole or tapped applications? Ensure adequate surface area and thread engagement depth for safe fastening.
