Mechanical Power is proud to announce the addition of two new Stainless Steel Shackles — available in 7/8″ and 3/8″ sizes — to our growing line of high-performance industrial components. Engineered for strength, precision, and corrosion resistance, these shackles deliver reliable performance in demanding environments where durability and safety are non-negotiable.

Whether you’re securing heavy loads, lifting equipment, or constructing marine assemblies, these new arrivals meet the highest quality and performance standards customers expect from Mechanical Power.

Product Overview

Our 7/8″ and 3/8″ Stainless Steel Shackles are crafted for precision and longevity. Both sizes are constructed from premium-grade 316 stainless steel, providing exceptional resistance to rust, saltwater corrosion, and chemical exposure — ideal for harsh industrial, marine, and outdoor applications.

7/8″ Stainless Steel Shackle
Built for heavy-duty lifting and load-bearing applications requiring superior tensile strength.

3/8″ Stainless Steel Shackle
Compact yet strong, suitable for smaller assemblies, rigging tasks, and general connection points.

Each shackle features a forged stainless body, machined threads, and a polished surface finish for enhanced strength, fit, and corrosion resistance. The smooth, precision-machined pin ensures secure closure while maintaining easy installation and removal.

Manufacturing Process

These shackles are manufactured through a closed-die forging process, followed by precision CNC machining to achieve exact dimensional tolerances. The threads and pin holes are then finished with high-speed polishing for optimal surface smoothness and reduced friction.

Key process steps include:
Forging: Ensures consistent grain flow and superior structural integrity.
CNC Machining: Delivers exact dimensional accuracy and smooth threading.
Electropolishing: Provides a clean, mirror-like surface finish and additional corrosion resistance.
Passivation Treatment: Removes surface impurities and enhances the natural oxide layer for long-term durability.

All shackles undergo rigorous tensile and proof-load testing to confirm mechanical strength and compliance with international standards.

Applications & Industries Served

Stainless Steel Shackles from Mechanical Power are trusted across a wide range of industries, including:

Marine and Offshore: Mooring, towing, and anchor systems.
Construction & Rigging: Crane lifting, hoisting, and load securing.
Transportation & Logistics: Tie-down and restraint systems.
Agriculture & Utility Equipment: Load-bearing joints and link assemblies.
Renewable Energy: Wind turbine and solar mounting structures.

Each shackle’s strength, corrosion resistance, and longevity make them an ideal fit for any operation where safety and reliability are critical.

Performance & Quality Assurance

At Mechanical Power, quality isn’t just a claim — it’s a process. All Stainless Steel Shackles are inspected and certified under ISO 9001:2015 quality management standards, ensuring each product meets or exceeds industry specifications.
