What are the differences between types of shackles?

Shackles are artificial in a spacious variety of types, styles, sizes, and fabrications, and with so many different privileges available, decide the right cumber for the thrust can be flustering.

 

Anchor shackle/bow shackle vs.chain shackle/D-shackle

Bow shackles and anchor shackles are terms that are often used interchangeably, as both names refer to a shackle with a larger, rounded “O” shape look. However, a bow shackle typically has a larger, more defined bow area than an anchor shackle. The rounded design of anchor shackles and bow shackles allow them to take loads from many directions without developing significant side load. The larger loop shape of an anchor shackle or bow shackle does reduce its overall strength, but it is also able to handle a larger strap.

Chain shackles are also known as D-shackles. Both refer to the “D” shape design. A d-shackle is narrower than a bow or anchor shackle and generally have a threaded pin or pin close. The smaller loop is designed to take high loads primarily in line. Side and racking loads may twist or bend a D or chain shackle.

 

 

What are the differences between types of shackles?

Both types of shackles are generally always available in galvanized  metal and stainless steel, and all come with different pin options as well.

 

Stainless steel vs. galvanized

Both stainless steel and galvanized metal offer excellent protection from rust and corrosion, making either a good choice.

In general, galvanized shackles are ideal for industrial applications where moisture is not a major issue. Galvanized steel has a thin coating of zinc oxide to protect the steel from elements that lead to corrosion and oxidation. Galvanized is also a great value as it tends to be less expensive than stainless steel, but still maintains the shackle’s strength and durability.

Stainless steel shackles are more corrosive-resistant and, are therefore ideal for marine applications. Our stainless steel shackles are made of type 316 stainless steel, which is considered “marine grade.” Type 316 marine grade stainless steel contains molybdenum, which makes it resistant to ocean water mist or spray, so it’s especially useful in extreme conditions or moisture or in a high chloride environment. Type 316 stainless D shackle equipment is ideal for sailing and yacht rigging uses.

 

Snap shackles

A snap shackle is designed with a spring-activated mechanism so it can be used quickly and with one hand. These are excellent for jobs where speed is important, or when it needs to be repeated connected/disconnected. Because they generally  have lower working load limits than comparable bolt type or pin type shackles, snap shackles are not recommended for heavy-duty applications. We offer four main types, all in Type 316 stainless steel: Swivel Eye, Swivel Jaw, Fixed Snap, and Rope Snap.

Pin options

The pin that locks a shackle can be a deciding factor on which will work best for your job. Pin styles range include loose pins, captive pins, round pins, screw pins, and bolt type pins. Screw pin shackles are popular because they offer a pin that is easy to connect and disconnect. Captive pin shackles offer a pin that cannot be removed from the bow of the shackle which is essential in various marine applications. Captive pins are also particularly popular for marine uses because they can’t be accidentally dropped in the water. Bolt type shackles secure with a bolt/nut/cotter pin combination and are popular for more heavy duty securement.
