The Ultimate Guide To Screw Pin Anchor Shackle Sizes

Screw pin anchor shackles are a versatile tool used for connecting lifting slings, wire rope, chain, and rope. They are ideal for a variety of rigging, lifting, pulling, and hoisting applications. They are also known as screw pin bow shackles due to their bow shape, which allows them to handle a wider variety of connections and multi-dimensional pulling tasks. The screw pin mechanism enables swift attachment and detachment, making it suitable for temporary lifting jobs or frequent connections and disconnections. Screw pin anchor shackles are commonly made of galvanized steel or stainless steel for durability, toughness, and corrosion resistance. They are available in various sizes and working load limits, ranging from a few tons to several tons.

Stainless steel screw pin anchor shackles

The screw pin configuration is best for temporary uses or applications that require repeated, quick connections and disconnections. They are often used as hardware for the eye of a lifting sling. Anchor shackles also help protect the eye of a polyester round sling from wear and tear.

Screw pins are effective at attaching and detaching, and the hole in the pin of the anchor shackle allows it to be wired shut. The shackle is typically made from Type 316 non-magnetic forged load-rated stainless steel, which provides a superior combination of strength and corrosion resistance.

Screw pin anchor shackles for hardware and industrial uses

Screw pin anchor shackles are a highly versatile tool used for connecting lifting slings, wire rope, chain, and rope. They are essential for rigging, lifting, pulling, and hoisting applications. They are also known as screw pin bow shackles.

Screw pin anchor shackles feature a large rounded shape that allows them to take loads from many directions without developing significant side loads. This makes them ideal for use with multiple-leg slings and for connecting slings to load rings. The screw pin configuration is best suited for temporary applications or those requiring quick connections and disconnections.

Screw pin anchor shackles are commonly used for hardware and industrial purposes and have a Working Load Limit of up to 3-1/4 tons. They are often made of galvanized steel for durability and toughness and feature a protective coating of zinc oxide to prevent corrosion and oxidation.

When selecting a screw pin anchor shackle, it is important to consider the specific application and choose a product that meets federal safety specifications. Proper safety inspections should also be conducted before each use, including verifying that the pin and body are of the same size, make, and type, and checking for any damage or undue wear on the pin and body.

Crosby screw pin anchor shackles

Crosby's screw pin anchor shackles are forged, quenched, and tempered with alloy pins. They are made of carbon steel and are available in a galvanized or self-coloured finish. The working load limit ranges from 1/2 ton to 3-1/4 ton, making them suitable for various applications such as tie-down, towing, suspension, or lifting.

Crosby shackles are known for their quality and are a respected brand in the rigging industry. They offer a range of screw pin anchor shackles with different sizes and working load limits to suit specific needs.

When using Crosby screw pin anchor shackles, it is important to inspect them before each use to ensure proper safety measures are followed. This includes verifying that the pin and body are of the same size, make, and type, checking for any damage, and ensuring that the safety bolt type shackles have the split cotter pin.

Screw pin anchor shackle maintenance

The screw pin anchor shackle, with the designation "02666," is a critical component in many applications, from boating and rigging to industrial settings. Proper maintenance of this shackle is essential to ensure its longevity and safety. Here are some detailed instructions on how to maintain this specific type of shackle:

Regular Inspections:

Conduct regular visual inspections of the screw pin anchor shackle. Look for any signs of wear, deformation, or corrosion on both the shackle body and the screw pin. Pay close attention to the screw thread and the mating surfaces of the shackle. Any damage or excessive wear indicates that the shackle should be replaced. These inspections should be done at regular intervals, depending on the frequency of use and the environment in which the shackle is used. For instance, in a marine environment, inspections should be more frequent due to the corrosive nature of saltwater.

Cleaning and Lubrication:

Keep the shackle clean and free of debris. Use a mild detergent and water to clean the shackle, ensuring that all dirt, grease, or salt deposits are removed. After cleaning, dry the shackle thoroughly. Lubrication is crucial to prevent corrosion and ensure smooth pin operation. Apply a light coating of marine-grade grease or lubricant to the screw thread and the underside of the shackle head. This will help protect the surfaces from moisture and corrosion while also making it easier to tighten and loosen the screw pin. Re-lubricate the shackle at regular intervals, especially after exposure to water or harsh conditions.

Screw Pin Maintenance:

The screw pin is the critical component of this type of shackle. Ensure that the pin is securely tightened and that the cotter pin or wire retaining mechanism is in place and secure. Check the condition of the screw pin's head, making sure it is not damaged or deformed. If the pin shows signs of excessive wear or corrosion, replace it. When tightening the screw pin, ensure it is securely fastened but avoid over-tightening, as this can deform the shackle or damage the thread.

Storage and Protection:

When not in use, store the shackle in a dry, protected environment. This will help prevent corrosion and extend its lifespan. If the shackle is used in a marine environment, rinse it with fresh water after each use and apply a coat of lubricant before storage. Avoid exposing the shackle to extreme temperatures, as this can affect the metal's strength and integrity. Also, ensure that the shackle is stored away from corrosive chemicals and substances that could damage the metal.

Replacement and Inspection Intervals:

Establish and follow a schedule for shackle replacement and thorough inspections. Even with proper maintenance, screw pin anchor shackles have a finite lifespan, and critical components such as the screw thread can wear out over time. Consult the manufacturer's guidelines for recommended replacement intervals, and ensure that any replacement shackles meet the same specifications and quality standards as the original. Thorough inspections, including close examination of the screw thread, mating surfaces, and the integrity of the metal, should be conducted at least annually, or more frequently in harsh or corrosive environments.

By following these maintenance instructions, you can ensure the safe and reliable use of the 02666 screw pin anchor shackle. Proper care will extend the life of the shackle, prevent failures, and provide peace of mind in any application where these shackles are employed. Remember always to err on the side of caution and replace the shackle if there is any doubt about its condition.

Screw pin anchor shackles for marine environments

Screw pin anchor shackles are a highly versatile tool, used for connecting lifting slings, wire rope, chain, and rope. They are used in a variety of rigging, lifting, pulling, and hoisting applications.

Screw pin anchor shackles are ideal for use in marine environments due to their resistance to corrosion and oxidation. They are constructed from stainless steel and feature a protective coating of zinc oxide. This makes them ideal for use in moisture-rich conditions.

Screw pin anchor shackles have a large rounded shape that allows them to take loads from multiple directions without developing significant side loads.
