Stainless steel shackle D 8 mm – code: 08.321.08 – Osculati

Stainless steel D shackle 8 mm Osculati (code 08.321.08)

The stainless steel D shackle 8 mm Osculati, identified by code 08.321.08, is a hardware component designed to create reliable connections in nautical and plant engineering contexts. The “D” shape is a classic solution for joining elements such as ropes, chains, or onboard accessories, maintaining a compact size and a geometry that is easy to inspect.

Made of AISI 316 stainless steel with finish polished, this shackle is suitable for environments where durable hardware is sought, also with attention to aesthetics. The declared machining is forged and the finish is mirror polished, typical characteristics of components intended for use in marine environments.

Features and construction details

Material and finish

• Material: stainless steel AISI 316.
• Finishing: polished, with indication of mirror polishing.
• Process: components forged.

AISI 316 stainless steel is commonly chosen in boating for its suitability to saline environments. The mirror-polished finish also facilitates routine cleaning and contributes to a neat appearance of the installation, especially on deck or in visible areas.

“D” shape and typical use

The geometry D is often preferred when a linear and compact connection is desired. Compared to other shapes, it allows working with a well-defined attachment point and a load distribution consistent with the traction axis, provided the shackle is used correctly and with compatible components.

Product size and identification

• Diameter: 8 mm.
• Supplier code: 08.321.08.
• SKU: OSCU00000170.
• Supplier: Osculati S.r.l.

To reduce errors during reorder or replacement, it is advisable to always refer to the Osculati code 08.321.08 as well as the nominal size.

Load capacities (declared values)

• Working load: 605 kg
• Breaking load: 2370 kg

These values are those associated with the variant of 8 mm indicated in the available data. When choosing, it is good practice to consider the entire system (connected components, direction of pull, usage conditions) and not just the shackle.

Applications in nautical and onboard plant engineering

The stainless steel D shackle is a versatile element, usable in many situations where a removable and inspectable connection is needed.

Deck connections and fastenings

• Connection between deck accessories and terminals (where provided by the project or outfitting).
• Quick connections at points requiring periodic maintenance or disassembly.
• Integration with chains, ropes, and compatible hardware accessories.

Maintenance and replacements

During maintenance, a polished stainless steel shackle is often chosen to replace worn or oxidized components, maintaining aesthetic and functional uniformity. The simple shape allows for quick visual inspection of the general condition of the component and contact surfaces.

Outfittings and technical systems

• Connections in systems or installations where a removable junction point is useful.
• General hardware applications in humid or marine environments.

If the application requires specific requirements (regulations, certifications, particular configurations), it is advisable to verify them in the project: this datasheet reports only the available data.

Main advantages

Material choice for marine environment

The use of AISI 316 stainless steel makes the shackle suitable for typical nautical contexts, where hardware is exposed to humidity, splashes, and salt spray. It is a common choice when a durable solution consistent with other stainless steel components on board is desired.

Mirror polished finish

The mirror polishing offers a neat and uniform appearance, particularly appreciated on visible installations. Furthermore, a well-finished surface can be easier to clean during routine maintenance.

Forging and construction care

The wording forged indicates a typical processing of hardware intended for technical uses. Combined with polishing, it contributes to a product with a professional finish, suitable for integrations on boats and systems where perceived quality and consistency with high-level components are required.

Clear identification for reorder

The presence of Osculati code 08.321.08 simplifies spare parts management and reordering, especially when operating on fleets, shipyards, or scheduled maintenance.

Usage and operational notes

Correct size selection

The nominal size of this item is 8 mm. Before purchase, check dimensional compatibility with the elements to be connected (for example, chain/rope diameter or thicknesses of attachment points) and with the available space in the installation area.

Assembly and checks

• Ensure that the shackle works consistently with its geometry, avoiding improper configurations.
• Perform periodic checks of tightening and surface condition, especially in marine environments.
• In case of obvious signs of wear or deformation, consider replacing the component.

Routine maintenance

To maintain the polished finish and reduce residue buildup, regular cleaning with products suitable for stainless steel and rinsing after exposure to salt spray is recommended. Avoid aggressive treatments unsuitable for polished surfaces.

Note on variants and data

The product family may include dimensional variants; this datasheet refers to the version 8 mm with working load 605 kg and breaking load 2370 kg, as per available data. For different needs, select the correct variant or contact support indicating the product code.
