STRAIGHT SHACKLES HR
High-performance Straight (D) Shackles HR forged from premium 17‑4 PH stainless steel with electropolished finish—designed for exceptional strength, durability, and corrosion resistance in heavy-duty marine and industrial applications.
Description
Gloma Nautica Straight “High Resistance” (HR) Shackles – 17‑4 PH Stainless Steel
Engineered for professionals who demand extra resilience, Gloma Nautica’s Straight HR Shackles are built using 17‑4 PH stainless steel, offering notably higher tensile strength and fatigue resistance compared to standard AISI 316 shackles. Their electropolished surface not only enhances aesthetics but also further boosts corrosion protection by eliminating micro-pits and smoothing the steel’s surface theriggingpoint.com+11glomanautica.com+11nautos-usa.com+11.
