Stainless steel swivel snap/shackle pin wire d. 8 – code: 01.439.01 – Osculati

Stainless steel swivel shackle/shackle with flush pin d. 8 Osculati (code 01.439.01)

The stainless steel swivel shackle/shackle with wire pin is a nautical hardware component designed for connections that require freedom of rotation and a practical coupling with shackles. This version, supplied by Osculati S.r.l. and identified by code 01.439.01, is made of AISI 316 stainless steel with finish mirror polished, indicated for typical onboard applications where a neat and marine environment-resistant solution is desired.

The proposed model is the variant shackle + shackle (wire pin) with wire diameter d. 8. The swivel is described as forged, a feature that makes it suitable for hardware uses where the robustness of the component is an important requirement.

Features and construction details

Material and finish

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

The use of AISI 316 stainless steel and mirror polishing make the swivel suitable for nautical and onboard system contexts, where hardware is exposed to humidity and splashes. The finish also contributes to a clean and professional appearance of the installation.

Shackle/shackle configuration with wire pin

• Version: shackle + shackle.
• Closing: wire pin (practical solution for assembly).
• Wire diameter: d. 8.

The configuration shackle/shackle facilitates integration with other connecting elements (chains, blocks, thimbles or accessories with shackle attachment), maintaining the swivel's typical rotation capability to reduce twisting of ropes and connections.

Forged for greater strength

The swivel is indicated as forged and “therefore very robust”. In the nautical field, the robustness of the component is a key aspect for connection continuity and for orderly management of maneuvers and onboard lines.

Product identification

• Supplier: Osculati S.r.l.
• Supplier product code: 01.439.01

The supplier code is useful for checks, reorders, and alignment with bill of materials or onboard spare parts.

Typical onboard applications

This stainless steel swivel is suitable for various nautical hardware uses, especially where a rotating connection is useful and where shackle attachment is the most convenient solution.

Recommended uses

• Buoys: connections and accessories where rotation can help manage twists and movements.
• Halyards: integration in maneuvering systems where the swivel can help keep the line more orderly.
• Anchor chains: use in connections where stainless steel hardware and shackle coupling are required.

The applications listed above reflect the uses indicated in the product description (buoys, halyards, anchor chains, etc.). For the correct choice of variant and size, it is always advisable to check the set of connected components and the available space in the installation.

Advantages in a nautical context

Neater and more functional connection

A swivel allows the connection to rotate following the movements of lines and loads, helping to limit unwanted twists. This is particularly useful when working with ropes, chains, or accessories that may rotate during use or with wave motion.

AISI 316 stainless steel and polished finish

The combination of AISI 316 and mirror polishing is typical of hardware intended for the marine environment. Besides the aesthetic aspect, the finish facilitates regular cleaning and integration with other stainless steel hardware on board.

Forged solution

The construction forged is a distinctive element for those looking for hardware described as “very robust,” suitable for recurring use on boats and onboard systems.

Usage and operational notes

Choice of the correct variant

This sheet refers to the version shackle + shackle (wire pin) with d. 8. When multiple variants of the same family exist (for example, configurations with an eye or with different sizes), it is important to select the one consistent with:

• type of required attachment (shackle/shackle in this specific case);
• diameter and dimensions compatible with the elements to be connected;
• available space and orientation of the connection.

Assembly and checks

During installation, ensure that the shackles work without interference and that the swivel can rotate freely. In a nautical context, it is good practice to perform periodic hardware checks (tightening, wear, sliding, and general conditions), especially if the component is used in exposed areas or subject to continuous movement.

Routine maintenance

To keep the hardware in good condition, regular cleaning with products suitable for stainless steel and rinsing after exposure to salt spray is recommended. Avoid unnecessary aggressive interventions that could alter the surface finish.
