Columbus Mckinnon m653a-g 7/8 in Galv Alloy Steel Screw Pin Shackle

Product Description

The COLUMBUS MCKINNON m653a-g is a 7/8-inch galvanized alloy steel screw pin anchor shackle built for heavy-duty rigging and lifting applications. The screw pin design allows for quick connection and removal without special tools, making it a practical choice for field rigging work. Galvanized alloy steel construction provides corrosion resistance for both indoor and outdoor use. Riggers, ironworkers, and industrial maintenance crews rely on this style of shackle where a removable pin and rated load capacity are required for safe load attachment.

This shackle is suited for use in construction rigging, marine environments, overhead lifting, and general industrial tie-down applications where a 7/8-inch anchor shackle is specified. The anchor-style bow provides a wider bearing surface compared to a chain shackle, accommodating slings, hooks, and multi-leg rigging arrangements. It is commonly installed by licensed riggers and millwrights following applicable ASME B30.26 hardware rigging standards.

Key Features

• 7/8-inch pin diameter galvanized alloy steel construction
• Screw pin design for tool-free installation and removal
• Anchor-style bow accommodates slings, wire rope, and chain
• Galvanized finish provides corrosion resistance for outdoor and marine use
• Alloy steel construction supports high working load applications

Compatibility

Designed as an OEM-style anchor shackle for use with standard 7/8-inch rigging hardware including wire rope slings, chain slings, and lifting hooks in industrial and construction rigging systems.

Installation Notes

Installation should be performed by a qualified rigger familiar with ASME B30.26 rigging hardware standards. Always ensure the screw pin is fully seated and moused when used in overhead lifting applications. Inspect the shackle for cracks, deformation, or corrosion before each use. Never side-load a shackle in a manner not consistent with its rated orientation.
