2. The different types of stainless steel shackles
With multiple stainless steel types shackles available, it may not be immediately clear which type is correct for a given application. Let me explore What Are the Differences?
- The traditional stainless steel bow shackle and d shackle are perhaps the most common types. Bow shackle (anchor shackle) features a large rounded shape body that allows taking loads from many directions without developing significant sideload, but d shackle can only be used for straight line applications.
- Bolt type shackle is similar to the bow shackle and dee shackle but the main difference it added a safety pin mechanism, which makes it more secure while taking loads, so it is excellent for permanent or long-term applications.
- Stainless steel long d shackle and wide d shackle stainless steel are also stainless steel d ring shackles, they feature a longer length and wider body for a high strength to weight ratio and maximum mounting area.
- Stainless steel twisted shackle is designed for 90 degrees perpendicular to the screw pin, allowing the two attachment points to reduce the twist without torquing.
- In its most basic form, snap shackle stainless steel is a roughly hollow section shaped shackle contain a spring-loaded captive pin, which stays locked and can’t be removed from the body. In order to open this pin, you must pull to engage the opening.
- Hilifting offers three types of snap shackles, fixed type, eye swivel and jaw swivel snap shackles, all the snap shackles have an identical circular shape, and come equipped with an Sprung plunger pin for quickly released to open and lock. But fixed type has a fixed end, non-twisting, cannot swivel as eye swivel and jaw swivel snap shackles, usually not recommended for applications that require twisting and spinning movement, are mainly for preventers, uphauls, downhauls, outhauls and and control lines. Both eye and jaw stainless steel swivel shackle can rotate 360 degrees, and pair with wire ropes or fibre ropes, which help prevent tangling, but jaw swivel type has a pin instead of an eye shaped opening.
3. What are stainless steel shackles used for?
Stainless steel shackles are ideal for yacht rigging, stair balustrades, decking, and architectural applications since they contain the elements chromium, nickel, and especially molybdenum, which help prevent against corrosive damage from saltwater. But they are commonly not rated for overhead lifting purposes.
Besides stainless steel d shackles and bow shackles, Hilifting offers varieties of carbon steel and alloy steel chain shackles, anchor shackles, lifting shackles for your straight line and multi-dimension pulling which can apply in low humidity or moisture with inexpensive compared to the stainless steel.

Both types of shackles are generally always available in galvanized carbon steel shackles and stainless steel shackles, come with different pin options as well. Stainless steel shackles and galvanized carbon steel shackles can offer protection from rust and corrosion, but the stainless steel shackles are the better choice for corrosive-resistant, due to it contains molybdenum element, which makes it resistant to moisture or in a high chloride environment, so we call this stainless steel shackles as type 316 marine grade shackles, you can check out this useful article to know the differences between stainless steel and carbon steel in the rigging industry.
