Latch with recessed stainless steel ring d. 8 – code: 01.081.08 – Osculati

Recessed stainless steel lyre shackle with d. 8 hex key pin (Osculati 01.081.08)

The toggle latch Osculati with recessed pin and hex socket is a nautical hardware component designed for reliable and tidy connections, particularly in configurations where it is useful to reduce protrusions and snag points. This version is made of AISI 316 stainless steel and is suitable for use in marine environments and generally in onboard applications where suitable materials and a compact geometry are required.

The model in question is identified by Osculati code 01.081.08 and refers to size d. 8. The “lyre” shape (also called “lira”) offers a wide opening and good versatility for connecting with chains, thimbles, and compatible accessories, maintaining a functional profile for installation on shackles and anchoring points.

Features and construction details

AISI 316 stainless steel

The shackle is made of AISI 316 stainless steel, a typical choice for hardware intended for nautical use due to its suitability for use in harsh conditions and in the presence of moisture and salt spray. This makes it suitable for external installations and for components exposed to atmospheric agents.

Recessed pin with Allen key tightening

The presence of recessed pin with hex key socket allows a clean tightening and reduces protrusions compared to solutions with a traditional pin. In many bow installations, this feature is appreciated because it helps maintain a more linear profile and limits interference with other components.

Guitar-shaped (lyre)

The guitar shape is often chosen when a practical connection is needed between elements with different sizes. The wider opening compared to a straight shackle can facilitate coupling with accessories and terminals, maintaining a neat assembly.

Size d. 8 and product identification

• Diameter: d. 8
• Supplier code: 01.081.08
• Brand / supplier: Osculati S.r.l.

For supply and spare parts consistency, it is advisable to always refer to the Osculati code as well as the size.

Typical applications in the nautical field

Anchor and bow connections

This shackle is suitable for use with anchors and bow systems where the shape and recessed pin can be useful. In particular, the manufacturer highlights that these shackles allow the anchor to slip into the bow rollers without jamming, an important aspect when a smoother lowering and retrieval is desired, reducing the possibility of jamming due to protrusions or non-optimized geometries.

Hardware joints and connections

Besides anchoring, a stainless steel guitar-shaped shackle can be used in various points on the boat where a removable and inspectable connection is needed: for example on deck accessories, temporary connections, or configurations requiring periodic disassembly for maintenance. Choosing the right size and checking the fittings remain essential for a correct assembly.

Practical advantages

Cleaner profile and fewer protrusions

The recessed pin contributes to a more compact assembly. In areas like the bow, where chain and anchor pass and where space is often critical, this solution can help maintain a tidier connection setup.

Material suitable for the marine environment

The’AISI 316 is a consistent choice for boating: it allows the creation of components intended to remain installed on board, with good resistance under typical marine environment conditions. Proper maintenance and periodic inspection are still recommended for all hardware.

Versatility of the guitar shape

The guitar shape offers a wide opening and a geometry that can be convenient when connecting elements with different terminals. It is a common solution for applications where a practical and functional shackle is desired without sacrificing a clean assembly.

Usage and operational notes

Assembly and tightening

For installation, use an appropriate hex key for the pin socket and tighten correctly, avoiding forcing. Before commissioning, it is good practice to check that the pin is fully seated and that the shackle operates without interference with the bow roller, chain, or other accessories.

Compatibility checks

The size d. 8 identifies the diameter of the shackle; for a correct match, it is also advisable to check the overall dimensions and compatibility with existing components (for example, passages in the bow roller and coupling with the anchor). In case of doubt, refer to the code 01.081.08 and the manufacturer's instructions.

Maintenance and inspections

As with all onboard hardware, periodic inspection of the shackle (body and pin) is recommended, especially if used in points subject to loads, vibrations, or continuous exposure. Regular cleaning helps keep the component in good condition and facilitates any disassembly.

Summary

• Guitar shackle in AISI 316 stainless steel
• Recessed pin with tightening at Allen screw
• Size d. 8
• Osculati Code: 01.081.08
• Usage indication: facilitates the insertion of the anchor into the bow roller preventing jamming (“getting stuck”)

If you are configuring or upgrading the bow hardware, this shackle represents a neat technical solution consistent with the typical needs of anchoring in the nautical field.
