Stainless steel swivel grillo/grillo pin wire d.10 – code: 01.439.02 – Osculati

Stainless steel swivel shackle/shackle with flush pin d.10 (Osculati 01.439.02)

The stainless steel swivel shackle/shackle with flush pin is a marine hardware component designed for reliable and neat connections, where it is useful to reduce twisting of ropes, halyards, or chains during use. This version Osculati (code 01.439.02) is made of AISI 316 stainless steel with finish mirror polished features configuration shackle + shackle with wire pin, a practical solution when a clean footprint and a more regular outer line are desired.

The product is suitable for typical edge applications and in the nautical plant sector, where the choice of materials and construction quality are central elements in maintenance and outfitting.

Features and construction details

Material and finish

• AISI 316 stainless steel
• Mirror polishing (well-finished appearance and easy to visually inspect)

Shackle/shackle configuration with wire pin

The swivel is in version shackle + shackle (wire pin). This configuration allows connections with elements equipped with an eye, chain, or accessories compatible with a shackle attachment, maintaining a more linear external profile thanks to the wire pin.

Forged construction

The body is forged: a machining typically chosen to obtain a solid component suitable for heavy-duty use in a marine environment. In practice, it is a solution appreciated when looking for “work” hardware, designed to last and to be easily handled during onboard operations.

Dimensions (selected variant)

The following dimensional references are available for this variant:

• D: 10
• A: 113
• B: 20
• C: 22

Note: the dimensions are reported as per product configuration and useful to verify the footprint and compatibility with existing hardware.

Typical onboard applications

This swivel is suitable for various uses in the marine field, where it is important to properly manage rotations and twists in connections:

• Buoysconnections between rope and accessories, with a neater system rotation.
• Halyardsuses where torsion can accumulate over time and a connection that accommodates it is preferred.
• Anchor chainsuses compatible with shackle connections, in outfitting and maintenance contexts.
• General connections on deck equipment and accessories, when a swivel joint is needed between two ends with shackle attachment.

In general, it is a useful component when a connection that remains more “in line” during use is desired and that helps manage movements and rotations without complicating installation.

Operational advantages

Reduction of twisting in connections

The presence of the swivel helps to limit the accumulation of torsion between two connected elements (for example rope/chain or rope/accessory), making system management neater during maneuvers and continuous use.

Material choice for marine environment

The use of AISI 316 stainless steel is typical of hardware intended for the marine environment. The finish mirror polished contributes to a clean appearance and facilitates visual inspection of the component's condition during periodic checks.

Practical solution with flush pin

The wire pin It is often preferred when a smoother profile with fewer protrusions is desired. This can be convenient in installations where space and smoothness near other components are aspects to consider.

Robustness of the forged construction

The construction forged It is a distinctive element for those looking for a swivel suitable for deck use, with a structure designed to work reliably over time, in contexts of use and maintenance.

Usage and installation notes

Verification of dimensions and matching

Before installation, it is advisable to check:

• the compatibility of the dimensions A/B/C/D with the available space and with the accessories to be connected;
• the correct coupling with any shackles, chains or terminals present on the system;
• the orientation of the connection, to maintain a neat working line.

Periodic checks

In the nautical field, it is good practice to carry out regular hardware checks: verify the general condition, cleanliness, and absence of visible anomalies. A swivel in good condition helps maintain smoother operation of the connection.
