Screw Pin Countersink Shackle, Ungalv, 25 Mm

This 25mm screw pin countersink shackle, also known as a Carver or endless shackle, is a vital rigging component for marine vessels. Its countersunk design minimizes obstruction and provides a flush profile. Essential for ship chandlery and vessel maintenance, this ungalvanized shackle offers reliable connection points.

Screw Pin — This Screw Pin Countersink Shackle, identified by IMPA code 230368 and sold per piece (PC), is a critical component within a ship's rigging equipment and general deck hardware. Its primary function is to connect ropes, wires, chains, or other lifting gear in a secure and reliable manner.

The countersunk design is a key feature, allowing the shackle to sit flush with the surface it’s attached to, minimizing interference and reducing the risk of snagging or obstruction. This makes it particularly suitable for use on deck fittings, winches, and other areas where space is limited. Selection of the correct shackle size is crucial for safe operation. The 25mm size indicates the internal diameter of the shackle bow.

Screw Pin

Screw Pin — Always ensure the shackle’s working load limit (WLL) is appropriate for the intended load. Improper selection can lead to failure and potential hazards. The 'Unglvanized' designation signifies that the shackle has not received a galvanizing coating. Screw Pin — This may be suitable for specific applications where corrosion resistance is not a primary concern, or where the shackle will be used in a protected environment.

However, for marine environments, consider the potential for corrosion and the need for regular inspection and maintenance. Procurement of this shackle is a routine requirement for ship chandlers and vessel maintenance departments. When requesting a quote (RFQ), clearly specify the product name, IMPA code (230368), unit of measure (PC), and any specific requirements regarding material or finish. Handling considerations include avoiding overloading the shackle beyond its WLL.

Regular inspection for signs of wear, corrosion, or deformation is essential. Damaged shackles should be immediately removed from service and replaced. This type of shackle is commonly used in mooring operations, towing, and general cargo handling. Proper installation is also important. Ensure the screw pin is securely tightened to the correct torque, and that the shackle is oriented correctly for the intended load direction.
