Description

Gloma Nautica Key‑Pin Shackles – Captive Key‑Pin, Forged AISI 316 Stainless Steel

Gloma Nautica’s Key‑Pin Shackles are precision-engineered for heavy-duty marine and industrial applications. These shackles are fully made in Spain from AISI 316 forged stainless steel, and feature a unique captive key‑pin mechanism that combines superior load-bearing capacity with enhanced user convenience and safety

Captive Key-Pin & Bar Design
These shackles include a captive key-pin secured via an integrated bar, ensuring the pin can rotate only half a turn to open or close—keeping it permanently attached to the shackle body and eliminating the risk of pin loss during operation nautos-usa.com. This design also allows effortless, tool-free manipulation—perfect for halyard and sail handling.

Forged AISI 316 Construction
Manufactured with industry-grade cold- and hot-forging processes, these shackles preserve optimal grain alignment for maximum tensile strength and fatigue resistance compared to non-forged counterparts. The AISI 316 material adds marine-grade corrosion resistance suitable for constant saltwater exposure .

High Load Capacity
Available in 5 mm (3/16″), 6 mm (1/4″), and 8 mm (5/16″) sizes, each variant is rated for demanding load requirements. While exact WLL/BREAK values vary by size, distributor pricing reflects premium quality and performance harbourchandler.ca+7nautos-usa.com+7nautos-usa.com+7.
