Professional Grade Marine Hardware: AIS 316 Bow Shackle
Engineered for the most demanding nautical environments, the AirowMarine 316 Stainless Steel Bow Shackle features a precision-cast, high-load bow structure. Unlike standard threaded pins that can back out due to vessel vibration, our safety bolt mechanism utilizes a triple-secure system consisting of a heavy-duty bolt, hex nut, and stainless split pin for absolute rigging security.
- Marine-Grade SS316: Forged with molybdenum for superior pitting resistance in high-salinity saltwater.
- Mirror-Polished Surface: High Ra precision finish reduces surface friction and prevents debris buildup.
- Safety Locking System: Nut and cotter pin design ensures fail-safe performance during anchoring, towing, or lifting.
- Load Certified: Precision casting supports working load limits (WLL) up to 520kg (12mm variant).
Ideal for yachts, center consoles, and industrial lifting applications where failure is not an option.
Frequently Asked Questions
- Why should I use a safety bolt shackle instead of a standard threaded pin shackle?
- Standard threaded pins can vibrate loose over time, especially in high-tension anchoring or engine-vibration environments. The AirowMarine safety bolt system uses a nut and stainless split pin, ensuring the connection remains physically locked regardless of vibration or movement.
- Is 316 stainless steel necessary for freshwater boating?
- While 304 stainless is often sufficient for freshwater, 316 stainless provides significantly higher resistance to pitting and crevice corrosion. If you ever plan to take your vessel into brackish or saltwater, the molybdenum content in 316 is essential for long-term safety and structural integrity.
- How do I choose the correct size for my anchor chain?
- The shackle size should typically match or exceed the diameter of your chain links. For example, an 8mm chain generally requires an 8mm or 10mm shackle. Refer to our WLL (Working Load Limit) table to ensure the shackle's capacity (up to 520kg for the 12mm) exceeds your expected loading requirements.
