Stainless steel cetra shackle d 16 mm – code: 08.421.16 – Osculati

The stainless steel lyre shackle d 16 mm Osculati (code 08.421.16) is a hardware component designed for reliable connections in nautical and onboard plant engineering. The “lyre” shape (also called “D”) is a classic solution when a compact and neat joining point is desired between ropes, chains, thimbles, eye bolts, or other fastening accessories.

Made of AISI 316 stainless steel and polished, this shackle is suitable for contexts where a refined finish and good corrosion resistance typical of marine environments are sought. The product is forged and mirror polished, features that contribute to a uniform and visually pleasing surface, as well as facilitating routine cleaning operations.

Product features and details

Material and finish

• Material: stainless steel AISI 316.
• Finishing: polished, mirror polished.
• Processing: forged.

“Lyre” (D) shape: what it means in practice

The D geometry is often chosen for connections where the load is guided along the main axis of the shackle. Compared to other shapes, it offers a compact profile and a linear arrangement of the attachment point. In onboard applications, it can be useful when space is limited or when the assembly needs to be tidy and easily inspectable.

• Working load: 2500 kg
• Breaking load: 10000 kg

Available dimensions for the selected variant

The following dimensions are reported for this configuration:

• A: 16 mm
• B: 32 mm
• L1: 64 mm
• R: 56 mm

Typical applications (nautical and onboard plant engineering)

This stainless steel clevis pin is suitable for multiple uses in the nautical hardware and maintenance of onboard systems and equipment, where removable and inspectable mechanical connections are required. In particular, it can be used for:

• connections between ropes, chains and fastening accessories;
• assemblies and leads on deck components (depending on the system configuration);
• joining points on equipment and accessories where a openable element is useful for quick interventions;
• installations and replacements where a finish consistent with other polished stainless steel hardware is desired.

The choice of the correct shackle always depends on the type of connection, the orientation of the load, and the set of components involved (rope/chain/accessory). In case of doubt, it is good practice to check the dimensions and load values required by the application.

Advantages

AISI 316 stainless steel for marine environments

The’AISI 316 it is commonly used in the nautical field for its suitability in environments exposed to humidity and salt. This makes the shackle a consistent choice for outdoor use and for components that require good durability over time, compatible with use and maintenance.

Mirror polished finish

The mirror polishing offers a professional appearance and a uniform surface. In practice, it can also help in routine cleaning operations and visual inspection, because any marks or surface oxidation become more evident during periodic checks.

Forging and construction care

The processing forged is typical of hardware intended for heavy-duty use. In a technical context, forging is often associated with a robust construction suitable for components that must work reliably within a connection system.

Practical and easily inspectable format

The shackle is a simple element to integrate and check: its structure allows for quick verification of the general condition of the component and the possible presence of deformations, signs of wear, or damage due to use.

Usage and operational notes

Size selection and dimension verification

Before installation, verify that the measurement d 16 mm and the dimensions A, B, L1, R are compatible with the accessory to be connected (for example, thicknesses, slots, lugs, or attachments). A correct fit avoids excessive play or interference that can compromise the functionality of the connection.

Mounting and periodic checks

• Make sure the shackle works in a configuration consistent with the intended connection and that the connected components are properly aligned.
• Perform periodic checks, especially in marine environments: cleaning, visual inspection, and verification of the general condition of the hardware.
• In the presence of obvious signs of wear, deformation, or damage, consider replacing the component.

Note on loads

The values of working load and breaking load indicated refer to the reported variant. In a real system, the overall capacity also depends on other connected elements (ropes, chains, accessories, and anchor points) and usage conditions. For critical applications, it is advisable to size the entire assembly consistently.
