Van Beest Green Pin 5/8" G-4161 Screw Pin Anchor Shackle - 3-1/4 Ton WLL

Green Pin® G-4161 Screw Pin Bow Shackle – The Rigger's Go-To for Speed, Strength & Confidence

When your operation demands hardware that connects fast, holds firm, and releases cleanly every time, the Green Pin® G-4161 Screw Pin Bow Shackle delivers. Trusted across construction sites, offshore platforms, and heavy industrial facilities worldwide, the G-4161 is the benchmark screw pin shackle for professionals who refuse to compromise on quality—or efficiency.

Quick-Connect Performance Without Sacrificing Strength

The G-4161's screw collar pin design is engineered for pick-and-place rigging: fast to install, easy to remove, and ready to go again. Whether you're running repetitive lifts, rotating rigging configurations, or need to mobilize and demobilize hardware quickly between jobs, the G-4161 keeps pace with your workflow without slowing down your crew. With working load limits spanning 0.33 to 55 metric tons and bow diameters from 5 mm to 65 mm (3/16" to 2-1/2"), there's a G-4161 sized exactly for your application.

Grade 6 Steel. Quenched. Tempered. Uncompromising.

Every G-4161 is forged from Grade 6 high-tensile steel, quenched and tempered to deliver a consistent, high-performance microstructure throughout the body of the shackle. The result is a component that resists deformation, fatigue, and impact loading—backed by a 6:1 safety factor (minimum breaking load equals 6× the working load limit), giving you a meaningful margin of safety above and beyond the rated load.

Hot-Dip Galvanized for the Long Haul

The G-4161's hot-dip galvanized finish provides multi-layer zinc protection that bonds directly to the steel surface, delivering superior resistance to salt spray, moisture, and chemical exposure. It's a finish built for the real world—not just the warehouse shelf.

Rated for Extreme Temperature Ranges

From Arctic construction projects to high-heat industrial facilities, the G-4161 performs reliably across a -40°C to +200°C (-40°F to +392°F) service temperature range—making it a genuinely versatile component across diverse global environments.

Certified for the Projects That Demand It

The G-4161 conforms to EN 13889 as standard and meets ASME B30.26 for sizes from 2 tons and up. For contracts requiring third-party documentation, optional certifications include DNV GL, CE marking, ABS PDA, and material test certificates upon request. Full traceability from mill to lift.
