<h3>About Columbus McKinnon</h3><p><strong>Columbus McKinnon</strong> is one of the most storied names in lifting, rigging, and motion control — a global manufacturer whose roots stretch back to 1875. What began as a focus on chains and hoists has grown, over more than 150 years, into a comprehensive portfolio of intelligent motion solutions trusted by engineers, riggers, and tradespeople across virtually every industry. From automotive assembly lines and offshore oil platforms to construction jobsites and live entertainment venues, Columbus McKinnon equipment is engineered to move materials safely and efficiently.</p><p>The company formally incorporated as Columbus McKinnon Corporation in 1929, following its acquisition of hoist manufacturer Chisholm Moore, and has never stopped innovating. Early milestones included the world's first alloy chain and the iconic CM Cyclone hand chain hoist, introduced in 1904 and still regarded as one of the most reliable manual hoists ever built. Today, Columbus McKinnon operates under a family of well-known brands — including CM, Yale, Coffing, Budgit, Duff-Norton, and STAHL CraneSystems — each bringing specialized expertise to lifting, motion control, and rigging applications worldwide.</p><p>At the heart of the Columbus McKinnon lineup is a commitment to safety, durability, and load-rated performance. Every product in the CM portfolio is engineered to help operators work smarter while improving safety and uptime on the job. The company's ISO-9001:2015 certification reflects a rigorous quality management culture that runs from design and production through installation and service.</p><p>For anyone working with rigging hardware, Columbus McKinnon's <a href="/7302-colombus-mckinnon-shackles-202507">shackles</a> stand out as some of the most capable on the market. The CM Super Strong Shackle line, forged and designed in Chattanooga, Tennessee, delivers working load limits up to 50% higher than comparable-sized carbon shackles — a result of proprietary microalloy materials and an air-cooling process that eliminates the risk of quench cracks. Whether you need standard anchor shackles, screw-pin designs, or the specialized long-reach styles that Columbus McKinnon is one of the only manufacturers to offer, the CM shackle lineup has a solution for virtually any rigging configuration.</p><p>Beyond shackles, Columbus McKinnon's <a href="/7302-colombus-mckinnon-wire-rope-sleeves-clamps-202775">wire rope sleeves and clamps</a> complete the picture for secure wire rope terminations and load connections. Drop-forged wire rope clips and heavy-duty thimbles from CM are proof-tested and built to the same exacting standards as the rest of the rigging line, making them a natural companion to any lifting or securing application where wire rope is involved.</p><p>From its century-and-a-half of manufacturing heritage to its ongoing investment in intelligent automation, Columbus McKinnon remains a benchmark brand for anyone who needs rigging and lifting equipment they can stake their safety on.</p>

Product Details

The Columbus McKinnon MC646G is a heavy-duty 1/4 inch galvanized carbon steel anchor shackle designed for lifting, rigging, and towing applications. This bow-type shackle features a screw pin design for quick attachment and release while maintaining secure load handling.

Key Features:

  • 1/2 ton (1,000 lbs) working load limit for reliable lifting capacity
  • 1/4 inch pin diameter for compatibility with standard rigging hardware
  • Hot-dip galvanized finish provides superior corrosion resistance for outdoor and marine environments
  • Drop-forged carbon steel construction ensures maximum strength and durability
  • Anchor (bow) style shackle design accommodates multiple connection points
  • Screw pin closure allows for easy opening and closing without tools

Anchor shackles are ideal for applications where the load may shift or where multiple slings need to be connected at a single point. The galvanized coating makes this shackle suitable for use in wet, humid, or corrosive environments where rust prevention is essential.

Cheapest price around. We&#039;ll see how fast I get it.

Thanks for the fast delivery

Very satisfied and received exact product sooner than expected

This was the first time I had ordered from Boatplicity, not having come across them in my previous searches for gear. As what I was looking for was a brand name product I selected purely based on price. The purchase process went seamlessly and the two items I bought showed up within a day of each other, both well within the delivery date promised. The items were well packaged and arrived undamaged, and were exactly as I had ordered and expected.

Quick easy checkout. Fair prices
