Twist link for 10-12 mm chain – code: 01.738.02 – Osculati

Twist joint for 10-12 mm chain Osculati (code 01.738.02)

The twist joint for chain Osculati is a component designed for mooring and anchoring, useful when, during recovery, the anchor tends to present itself to the bow roller in the wrong direction. With modern asymmetric anchors (Bruce, Delta, Trefoil® etc.) this situation can occur quite frequently: the joint helps to rotate the anchor in the right direction while it is inserted into the bow roller or the chock, making the weighing phase more orderly.

Made of AISI 316 stainless steel with finish mirror polished, it is suitable for installations in marine environments where a refined accessory consistent with deck hardware is sought. The connection to the anchor is made via cricket, , which connects the fixed eye of the shackle to the anchor.

Features and construction details

Material and finish

• AISI 316 stainless steel.
• Mirror polished, for a clean and uniform appearance with the edge hardware.

Function of the twist shackle

The shackle is designed to promote the correct orientation of the anchor during retrieval, especially when the anchor arrives at the bow roller turned. Instead of having to intervene manually or wait for the anchor to settle, the twist helps to rotate it as it enters the bow roller passage.

Chain compatibility

• Chain Ø mm: 10/12.

Dimensions (as per datasheet)

• A: 320 mm
• B: 83 mm
• C: 38 mm

Connection with shackle

A cricket connects the fixed eye of the shackle to the anchor. Based on the indicated configuration, the shackle codes listed as reference are:

• 01.080.10
• 01.080.12
• 01.080.14

Note: always verify the correct choice of shackle depending on the anchor and the onboard installation.

Typical applications (mooring and anchoring)

This twist shackle is suitable for anchoring systems where you want to improve anchor handling during retrieval, especially with asymmetric anchors. It is a useful accessory in contexts such as:

• Sailboats and motorboats with bow roller where the anchor must return with a precise orientation.
• Systems where the anchor, during hoisting, tends to present itself rotated compared to the correct seating.
• Setups where you want to maintain a neat line between chain, shackle, and anchor, reducing manual interventions at the bow.

Practical advantages

• Helps the anchor to return in the correct direction during insertion into the bow roller or the hawse pipe.
• Reduces uncertainties typical of recovery with asymmetric anchors (Bruce, Delta, Trefoil® etc.).
• Polished finish and AISI 316 material: a solution consistent with nautical use and deck hardware.
• Simple installation via shackle on the fixed eye (classic and easily inspectable configuration).

Usage and installation notes

General indications

To achieve smooth operation, it is important that the joint is correctly inserted in the line between chain and anchor and that the passage through the bow roller/hawse pipe is compatible with the dimensions and geometries of the anchor-chain assembly. During assembly:

• use a suitable shackle to connect the fixed eye of the joint to the anchor;
• check that there are no interferences with the bow roller/hawse pipe during retraction;
• periodically verify the condition of the connections (shackle, pin, any signs of wear or deformation).

Routine maintenance

In a marine environment, it is good practice to perform visual inspections and periodic cleaning of the hardware. The polished finish facilitates inspection and helps identify any abnormal signs. After intensive use or long stays at sea, rinsing with fresh water and checking the shackle tightness help keep the assembly in order.
