Stainless steel recessed pin shackle d. 5 – code: 01.080.05 – Osculati

Recessed pin stainless steel shackle for marine applications

The recessed pin shackle Osculati code 01.080.05 is a hardware component designed for use in the marine field, where compact dimensions and a neat coupling with bow accessories are required. The peculiarity of the recessed pin, with hex socket, helps maintain a cleaner line compared to traditional pin crickets and is practical when you want to reduce protrusions and snag points.

Made of AISI 316 stainless steel, it is suitable for typical onboard uses and for connections on the anchor line, where the compactness of the pin can facilitate the sliding and insertion of the anchor into the bow rollers, helping to prevent the anchor from snagging during maneuvers.

Features and construction details

Material: stainless steel AISI 316

The shackle is made of AISI 316 stainless steel, a common choice in marine hardware for use in a marine environment. The material is suitable for onboard contexts and installations where a durable solution consistent with the rest of the stainless steel components is sought.

Recessed pin with hex key slot

The recessed pin is designed to reduce protrusions. Tightening is done via hex socket, a solution that allows for neat assembly/disassembly action with a dedicated tool, useful when you want to limit the use of protruding elements or when maneuvering space is limited.

Function near the bow roller

This type of shackle is suitable for use with anchors because it allows the anchor to fit into the bow rollers without jamming. In practice, the geometry and the absence of protruding parts of the pin can facilitate a smoother passage during retrieval and stowage.

Product size

The variant proposed here is d. 5. For the correct choice, it is always advisable to check dimensional compatibility with the chain, existing shackles, anchor attachments, and the geometry of the bow roller.

Typical onboard applications

Below are some common applications, to be understood as general examples (the final choice always depends on the system sizing and installation requirements).

Anchor line and bow connections

• Connection between anchor and accessories of the anchor line, when you want to facilitate insertion into the bow roller.
• Use in points where the presence of a protruding pin could cause interference during retrieval or stowage.

General hardware and quick connections

• Connections on deck equipment where a stainless steel element with a cleaner profile.
• Use in maintenance and refitting, when worn shackles are replaced with a recessed pin solution.

Practical advantages of the recessed pin

Less protrusion and fewer snag points

The recessed pin reduces parts that protrude beyond the shackle body. This can be useful near guided passages (such as the bow roller) or where ropes, chains, and accessories run and could snag.

Neat assembly with dedicated tool

The hex socket allows intervention with a suitable wrench, facilitating more controlled tightening compared to solutions requiring external grips. It is a feature appreciated when working in tight spaces or when a cleaner overall appearance is desired.

Solution consistent with onboard stainless steel hardware

The use of AISI 316 makes the shackle suitable for integration into systems and hardware already made of stainless steel, maintaining uniformity of materials and finishes typical of nautical outfitting.

Usage and installation notes

To achieve correct assembly and reduce operational issues, it is good practice to consider some aspects before installation. The following indications are generic and do not replace onboard procedures or installation specifications.

Dimensional check before assembly

• Check that the size d. 5 be consistent with the elements to be connected (for example, anchor attachment and the component it connects to).
• Check that the shackle can move correctly without interference and that the assembly passes through bow roller smoothly.

Allen bolt tightening

• Use a well-maintained Allen key of the correct size to avoid damaging the socket.
• During periodic maintenance, check the condition of the bolt and the ease of opening/closing, especially if the component is used in areas prone to dirt or deposits.

In a nautical environment, it is good practice to carry out periodic checks of fastenings and the order of wiring/piping. If a clip is damaged or no longer suitable for containment, replacement with an equivalent spare (same size and code) helps maintain system consistency.

As with all onboard hardware, it is advisable to regularly inspect the shackle, checking for the absence of deformations, abnormal wear, or unwanted play. If in doubt about suitability for the specific application, it is advisable to consult a technician or the system documentation.
