Stainless steel Cetra shackle mm 5 – code: 08.421.05 – Osculati

Stainless steel cetra shackle 5 mm Osculati (code 08.421.05)

The stainless steel cetra shackle 5 mm Osculati is a hardware component designed for connections and fastenings in nautical and onboard plant engineering, where careful finishes and materials suitable for the marine environment are required. Made of AISI 316 stainless steel, it is suitable for installations where a compact, tidy, and easily inspectable element is desired.

This version is forged and mirror polished, features that contribute to a good perceived quality and a finish suitable for visible contexts (deck, accessories, equipment). The supplier's product reference is 08.421.05.

Features and construction details

Material and finish

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

“cetra” shape”

The geometry zither is a typical configuration of shackles used in nautical hardware, useful when a clean connection and a size consistent with onboard accessories and equipment are desired. The choice of shape should be evaluated based on the fastening point and the type of element to be connected (rings, thimbles, terminals, plates, or accessories).

Dimensions and load capacities (5 mm variant)

For this configuration mm 5 the following values are available:

• A: 5
• B: 10
• L1: 20
• R: 17
• Working load: 250
• Breaking load: 1000

Note: the values shown are those associated with the selected variant. When choosing and installing, it is good practice to verify that dimensions and loads are consistent with the actual application and with other components of the line (cables, chains, accessories, and anchor points).

Typical applications in the nautical field

An AISI 316 stainless steel shackle with a polished finish is commonly used in many onboard outfitting and maintenance activities. In particular, it can be useful for:

• Connections between deck accessories and anchor points.
• Fastenings on equipment and components where tidy and inspectable hardware is required.
• Pulleys and connections on lines and terminals, when the shape and size of the shackle are suitable for assembly.
• Maintenance interventions and replacement of small parts subject to wear or corrosion in the marine environment.

The correct application depends on the system design and the type of expected stresses. If the use is critical, it is advisable to evaluate the set of components and the correct sizing of the line.

Advantages for installation and maintenance

• AISI 316 stainless steel: material commonly chosen in the nautical field for use in the marine environment.
• Forging: typical processing of hardware intended for technical applications.
• Mirror polishing: finish suitable for visible installations and easier to visually check during inspections.
• Practical size: suitable for integration with other onboard hardware, especially when a compact and tidy component is desired.
• Clear coding: identification via Osculati code 08.421.05 for reordering and spare parts management.

Usage and operational notes

Size selection

The size mm 5 should be selected based on the diameter/size of the elements to be connected and the available spaces. In addition to the nominal size, it is important to also consider the dimensions (A, B, L1, R) to avoid interference with plates, eye bolts, thimbles, or other accessories.

Installation and checks

• Ensure that the contact surfaces are clean and that the shackle operates correctly, without obvious forcing or misalignments.
• Periodically check the condition of the hardware and the possible presence of signs of wear, deformation, or damage.
• In case of replacement, maintain consistency between the line components (materials and dimensions), avoiding combinations unsuitable for the environment or intended use.
