Stud link anchor chain AM2 is a specific type of anchor chain widely used in marine applications. It's characterized by having a stud (a crossbar or bar) within each link, adding strength and preventing kinking or twisting. AM2 is a designation within the marine industry for a specific grade of this chain, indicating its strength and material properties. 

Stud link anchor chains are a type of heavy-duty chain commonly used for anchoring and mooring vessels. They have a central stud in each link that helps to prevent kinking, deformation, and fouling. These chains are known for their strength and are often preferred for large vessels and applications where significant loads are involved.

A G2130 Bolt Type Anchor Shackle is a type of shackle, specifically a bolt-type shackle, used in lifting and rigging applications where a high level of security and reliability is required. These shackles are designed with a bolt, nut, and cotter pin, which provides a more secure connection than traditional screw-pin shackles, especially in situations where the shackle might experience rotation or movement under load.

A G209 anchor shackle, manufactured by Crosby, is a high-performance, forged, screw-pin anchor shackle designed for heavy-duty lifting and rigging applications. They are known for their strength, corrosion resistance, and ability to meet or exceed industry standards like ASME B30 and DNV.
