Green Pin Lifting Eye UNC (ALUNC)

Green Pin Lifting Eye UNC (ALUNC)

The Green Pin ALUNC lifting eye bolt features a UNC (Unified National Coarse) thread for direct installation into tapped holes on machinery, equipment, and fabricated steel structures. Forged from alloy steel with a higher capacity than standard DIN 580 eye bolts, these lifting points provide a secure overhead lifting connection when permanent or semi-permanent lifting points are needed.

Key Features

• Forged alloy steel construction
• UNC thread for North American standard tapped holes
• Higher WLL than standard DIN 580 eye bolts
• Proof tested at 2x WLL
• Self-indicating for thread engagement verification
• Shoulder design prevents unscrewing under load

Available Sizes

Installation

Thread must be fully engaged with shoulder seated flat against the surface. Never use without full thread engagement. Do not side-load standard eye bolts beyond 45° from the vertical axis. For angular loading, use swivel hoist rings instead.

Inspection & Safety

Before every use: visual check for cracks, corrosion, distortion, wear, and illegible markings. Annually (minimum): documented periodic inspection by a trained inspector. Remove from service at first sign of damage. Never repair rigging hardware by welding, heating, or bending.

WARNING: Improper use of rigging can cause death or serious injury. Never exceed the rated Working Load Limit. Apply derating for side-loading, elevated temperature, or chemical exposure. Final application decisions must be made by a Qualified Person per OSHA 1926.32(m).
