McMaster 3663T44 Galvanized Alloy Steel Shackle with Screw Pin - for Lifting, 3/4" Thick
Your go-to choice for connecting hooks, slings, and other rigging and lifting equipment. The rounded body on these shackles supports vertical or side loads without fatiguing or warping the shape. They meet ASME specifications for rigging and lifting, so they can hoist everything from steel beams to bulldozers. Look for the manufacturer's stamp to confirm the size and weight capacity. Also known as bow shackles.
Note: Capacities listed are for vertical lifting only. As the lift angle changes from vertical, the amount of weight the shackle can lift is significantly reduced.
Screw Pin—The most common shackle pin type. Although the pin easily connects and disconnects, it can come unscrewed or wear down over time, so it's best for temporary use.
High-Strength Galvanized Alloy Steel—Stronger than galvanized steel with corrosion resistance in wet and outdoor environments.
