Machining: Precision drilling and threading for smooth pin operation.
Heat Treatment: Stress-relieving to enhance strength and durability.
Surface Finish: Polished or electropolished to reduce friction and improve aesthetics.
Quality Testing: Load testing, salt spray testing, and dimensional checks.
Products Application
Marine: Rigging, sailboat hardware, anchor connections.
Industrial: Lifting slings, crane systems, safety equipment.
Outdoor: Climbing gear, zip lines, forestry applications.
General Use: Securing cargo, trailers, or construction loads.
FAQ
Q1: Why choose 316 over 304 stainless steel?
A: 316 offers better corrosion resistance, especially in saltwater, due to added molybdenum.
Q2: Can the spring mechanism be replaced?
A: No, the spring is fixed and integral to the shackle's design for permanent security.
Q3: How do I maintain the shackle?
A: Rinse with fresh water after salt exposure; inspect regularly for wear or deformation.
Q4: Is galvanic corrosion a concern?
A: Avoid direct contact with dissimilar metals (e.g., aluminum) in wet environments.
Q5: Are custom sizes available?
A: Yes, contact us for OEM specifications (min. order may apply).
