US Type 316 Stainless Steel Bow Shackle with Over Size Screw Pin

In this review the MarineNow US Type 316 Stainless Steel Bow Shackle with Over Size Screw Pin is assessed for boaters, off-roaders and anyone needing a corrosion-resistant connector. The bottom line: this shackle is for users who want a tough, marine-grade stainless steel fitting with smooth threads and a reliable screw pin for quick attachment. Its principal advantage is long-term corrosion resistance and strength in humid or salty environments, making it a practical choice for anchor chain, towing points, and recovery rigs.

Key Features

• Marine-grade construction: Made from US type 316 stainless steel to provide superior resistance to rust and corrosion in saltwater and humid conditions.
• Over size screw pin: The larger screw pin offers easier handling, secure closure and fast removal during anchor or towing operations.
• Versatile applications: Suitable for anchoring, towing, road recovery and sailing hardware, so it fits a variety of marine and outdoor tasks.
• Multiple sizes available: A wide range of diameters and pack counts lets you choose the right shackle for the load and rigging geometry you need.
• Rated working load limits: Each size is specified with a Working Load Limit, ensuring you can match the shackle to expected loads safely.

Who It's For

The shackle is aimed at boat owners, sailors and overlanders who need a corrosion-resistant, reliable connector for anchors, snatch straps and towing setups. It is also appropriate for marine maintenance crews or anyone replacing worn shackles exposed to salt air.

It may be less suitable for users who need an unusual custom fitting or a threaded pin design other than an over size screw pin; if you require a captive pin or different locking mechanism, look for specialized rigging hardware instead.

Pros & Cons

Pros
