Gloma Nautica Shackle Spanner

The Gloma Nautica Shackle Spanner is a compact, heavy-duty marine tool crafted to deliver reliable performance wherever shackles are used. Precision-engineered in Spain from AISI 316 stainless steel, this spanner is designed to engage a wide range of standard shackle pin sizes—ensuring safe, secure tightening and loosening without damaging hardware or fingers ([glomanautica.com][1]).

Forged rather than cast, each Gloma shackle spanner benefits from internal grain alignment, which significantly increases its mechanical resilience. This forging technique avoids weak points common in cast tools and ensures the spanner can handle repetitive high-torque applications with confidence. Whether working on a sailboat, a commercial vessel, or an industrial rigging project, the tool’s strength and reliability make it an essential part of any marine toolkit.

The tool’s shape features multiple cutouts and pin slots, purpose-built to fit various shackle head designs and sizes, including bow shackles, D shackles, captive pin shackles, and high-resistance (HR) shackles. This multi-size compatibility eliminates the need for several separate tools, making it ideal for fast-paced environments where space and time are at a premium.

Gloma Nautica finishes each shackle spanner with a polished surface that not only offers aesthetic appeal but also provides protection against corrosion, pitting, and oxidation. The AISI 316 stainless steel used in construction includes molybdenum—offering industry-leading resistance to saltwater, acids, and harsh chemical exposure. Even in constant contact with seawater, the spanner maintains its form, surface integrity, and operational safety.

The spanner’s compact and ergonomic design allows for a firm, slip-resistant grip, even when wearing gloves or working in wet conditions. Its slim profile makes it easy to carry in a pocket, toolbox, or clipped to a lanyard for on-deck accessibility. The absence of moving parts or plastic components means maximum durability and virtually no maintenance requirements.

Used worldwide by yacht crews, marine technicians, riggers, and naval architects, the Gloma Nautica Shackle Spanner ensures shackles are torqued to the appropriate tension—preventing accidental loosening due to vibration or underload. It also eliminates common problems like over-tightening with makeshift tools, which can damage the threads or compromise stainless steel integrity.

Manufactured in Cabrera de Mar, Barcelona, under Gloma’s rigorous quality protocols, each spanner is dimensionally verified and quality-checked for consistent fit across standard shackle ranges. With full traceability and a design honed from decades of marine hardware experience, this spanner reflects Gloma Nautica’s dedication to precision, safety, and usability.

Compact, tough, and corrosion-proof, the Gloma Nautica Shackle Spanner is the tool of choice for safe, professional rigging in any maritime or industrial environment.
