Gloma Nautica Twisted Captive‑Pin Shackles — Forged AISI 316 Stainless Steel
Gloma Nautica’s Twisted Captive‑Pin Shackles deliver exceptional performance and safety in complex rigging setups. Manufactured in Spain using fully forged AISI 316 stainless steel, each shackle is expertly cold- or hot‑forged for optimal grain orientation—a method that enhances strength, fatigue resistance, and identifiable over‑stress deformation
Precision 90° Twist Design
What makes these shackles truly exceptional is their 90-degree twist in the shackle body. This angled design aligns rigging elements perpendicularly with the screw‑eye pin, preventing torsion and ensuring smooth load transfer—especially useful for blocks on rails, perpendicular lines, and complex deck hardware setups marine.wichard.com.
Captive Screw‑Eye Pin for Safety
Equipped with a captive screw‑eye pin, the design ensures the pin remains secured to the shackle body at all times—eliminating risks of loss and providing vibration-resistant closures. The integrated eye also facilitates easy manual operation, even in wet or instrumented environments .
Certified Strength Ratings
Available in pin diameters from 4 mm to 10 mm, Gloma’s twisted captive-pin shackles offer traceable Working Load Limits (WLL) and breaking loads tested and certified by APPLUS. Examples based on distributor data:
| Pin Ø (mm/in) | Inside Width (mm) | Inside Length (mm) | WLL (kg) | Breaking Load (kg) |
|---|---|---|---|---|
| 4 mm (5/32") | 8 | 30 | 400 | 1,000 |
| 5 mm (3/16") | 10 | 38 | 600 | 1,500 |
| 6 mm (1/4") | 12 | 45 | 900 | 1,800 |
| 8 mm (5/16") | 16 | 58 | 1,700 | 4,300 |
| 10 mm (3/8") | 20 | 70 | 2,500 | 5,700 |
Marine‑Grade Durability
Made from AISI 316 stainless steel, these shackles are built to handle constant exposure to saltwater and harsh marine elements. Their polished finish simplifies maintenance while allowing quick visual inspections.
Built‑in Safety & Warranty
Designed to deform before failing, the forging process provides a critical safety buffer. Gloma Nautica supports these shackles with a 5‑year warranty, ensuring long-term dependability and confidence on deck riggingshoppe.com+5nautos-usa.com+5nautos-usa.com+5.
