Extra long stainless steel shackle 12 mm – code: 08.323.12 – Osculati

12 mm Osculati super long stainless steel shackle (code 08.323.12)

The 12 mm super long stainless steel shackle Osculati, code 08.323.12, it is a hardware component designed for connections and fastenings where a more extended geometry compared to a standard shackle can be useful. Made of AISI 316 stainless steel and with a finish polished, it is suitable for nautical applications and generally for uses where durable and finely detailed hardware is required.

The “extra long” version is often chosen when more useful length is needed or when a tidier connection between elements is desired (for example with redance, eye bolts, plates, or other deck accessories), maintaining a practical and inspectable link.

Features and construction details

This shackle is forged and mirror polished. The use of AISI 316 stainless steel makes it suitable for contexts where corrosion resistance is an important requirement, typically in marine environments or in the presence of moisture and splashes.

Material and finish

• Material: stainless steel AISI 316
• Finishing: polished (mirror polishing)
• Processing: forged

Dimensions (12 mm version)

Below are the available sizes for this variant:

• A: 12 mm
• B: 24 mm
• D: 24 mm
• L2: 96 mm

Declared loads

For the 12 mm variant, the following values are reported:

• Working load: 1401 kg
• Breaking load: 5490 kg

Note: the indicated loads are those associated with this specific version. When choosing and installing, it is good practice to consider the entire system (connected components, load directions, usage conditions) and use accessories consistent for sizing and use.

Product identification

• Manufacturer/Supplier: Osculati S.r.l.
• Supplier product code: 08.323.12
• Type: extra-long stainless steel shackle

Typical applications (nautical and plant engineering)

An extra-long shackle is normally used as a connecting element between metal parts or between hardware and ropes/cables, when the extended shape helps manage assembly or reduce interference with other components. In nautical contexts, it can be used in various points of the rigging and deck, depending on the design and mounting needs.

Examples of use

• Connections between eyebolts, plates and deck accessories
• Connections with maneuvering elements where a greater length of the shackle body
• Assemblies where a connection is desired inspectable and easily removable for maintenance
• Generic uses of stainless steel hardware in humid or marine environments

Advantages of the extra-long shackle in AISI 316 stainless steel

The choice of an AISI 316 shackle with polished finish is often linked to durability needs, installation order, and perceived quality of the hardware. The extra-long geometry can also simplify some mounting configurations compared to a traditional shackle.

Strengths

• Corrosion resistance typical of AISI 316 stainless steel, suitable for nautical uses
• Mirror polished finish, also useful where the hardware's aesthetics are important
• Forged body, common construction solution in hardware intended for heavy-duty use
• Super long format to manage connections with greater clearance and to reduce possible interference
• Declared loads available for more informed sizing (working load and breaking load)

Usage and installation notes

To achieve correct assembly, it is advisable to check that the connected parts work in alignment and that the shackle is not subject to abnormal stresses due to torsion or improper supports. In the presence of moving components or vibrations, it is useful to schedule periodic checks of the hardware condition.

Good practices

• Verify that the dimensions (A, B, D, L2) are compatible with the elements to be connected.
• Consider the working load in relation to the application and the rest of the line (cables, redance, shackles, plates, etc.).
• Perform periodic inspections to check wear, deformation, or signs of corrosion.
• In case of replacement, maintain consistency between materials and components (stainless steel hardware with stainless steel hardware) for a neat and homogeneous installation.

Note on size selection

This sheet refers to the variant from 12 mm (code 08.323.12). If you are comparing multiple sizes of the same series, it is advisable to base your choice on the declared dimensions and loads to identify the version best suited to your system.
