Stainless steel shackle with 5 mm diameter – code: 08.321.05 – Osculati

5 mm stainless steel D shackle Osculati – code 08.321.05

The 5 mm stainless steel D shackle Osculati (code 08.321.05) is a hardware component designed to create reliable connections between onboard elements and accessories, when a practical and inspectable joining point is needed. The shape D It is a common solution in the nautical and plant engineering fields to connect ropes, cables, chains, or terminals to eye bolts, plates, and other anchoring points.

Made of AISI 316 stainless steel and polished, , this shackle is suitable for contexts where a refined finish and a material commonly used in marine environments are sought. The processing is declared as forged and mirror polished, , in line with the quality approach of the Osculati brand for onboard hardware.

Features and construction details

Material and finish

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

These characteristics make the shackle suitable for installations where the hardware is exposed and a neat appearance is desired, as well as a material choice typical for use in nautical environments.

D geometry

The D shape is often chosen when a compact connection with a simple profile is desired. In many onboard applications, it allows orderly management of the connection point between two elements, also facilitating visual inspections and assembly/disassembly operations.

Dimensions and data of the 5 mm variant

For this version the following values are available:

• A: 5 mm
• B: 10 mm
• D: 10 mm
• L1: 20 mm
• Working load: 232 kg
• Breaking load: 910 kg

Note: The load values are reported as per the data available for the selected variant. When choosing, it is good practice to consider the actual application, the orientation of the load, and the general condition of the connected components.

Product identification

• Supplier: Osculati S.r.l.
• Supplier product code: 08.321.05

The code is useful for reorders, bill of materials, and to maintain consistency between spare parts and components already installed.

Typical applications (nautical and onboard plant engineering)

A stainless steel D-shackle is commonly used as a joining element in many configurations.

• Hardware connections between accessories and anchoring points (e.g., eye bolts, plates, rings).
• Connections between ropes/cables/chains and terminals, when a removable element is needed.
• Fittings and maintenance where it is useful to be able to open the connection for inspection or replacement of parts.
• General uses on equipment and onboard accessories where stainless steel hardware is used.

The choice of size (in this case 5 mm) must be made based on the available space and the expected loads, maintaining consistency with the other components of the line (cables, terminals, attachments).

Practical advantages

Simple and inspectable solution

The shackle is an intuitive component: it allows creating a connection point that can be opened and closed when necessary, facilitating maintenance and accessory replacement without having to dismantle entire sections of the system or setup.

Careful finish for visible installations

The polishing (indicated as mirror finish) is a detail appreciated when the hardware remains visible. It helps maintain a neat appearance consistent with other stainless steel parts on board.

Typical material for marine environment

The use of AISI 316 stainless steel is a common choice in the nautical field. It is suitable when stainless steel hardware is desired for exposed contexts, in line with typical onboard requirements.

Osculati code for spare parts management

The reference 08.321.05 allows faster handling of reorders and replacements, useful both for professionals and those who manage scheduled maintenance.

Usage and operational notes

Mounting instructions

• Check that the parts to be connected are compatible in size with the shackle's opening and the available sizes.
• Ensure that the connection works in a orderly, , avoiding configurations that may cause twisting or abnormal supports.
• Perform periodic visual inspection of the hardware, especially in case of frequent use or repeated stresses.

Size selection

This sheet refers to the variant 5 mm. Other sizes are available in the same product family; for uniformity of the system, it is advisable to choose the shackle consistent with the other components already installed (dimensions and reference loads), avoiding “forced” combinations.

Note on loads

The values of working load and breaking load are reported as per data available for the variant. In critical applications, it is appropriate to evaluate the entire system (connected components, usage conditions, wear, assembly) and adopt adequate safety criteria.
