Shackles are one of the most used rigging fittings. Our stainless steel bow shackles with safety pins are better for safety as they cannot come loose accidentally. We can provide screw pin bow shackles such as g-209 bow shackles, or commercial bow shackles. And it's important to note that screw pin d shackles should only be used for straight-line applications. The square head trawling shackles are commonly used in the marine industry for trawling purposes.

Stainless steel snap shackles have a quick-release pin and a fixed eye, suitable for numerous applications in highly corrosive marine environments. Our swivel shackles rotate 360°.

Stainless steel shackles are great for marine or high-humidity applications. Shackles must always be inspected for wear, distortion and damage before use. If the pin or bow is worn, distorted or damaged, discard the shackle.

Types of Stainless Shackles

Materials of Stainless Steel Shackle

The common stainless steel shackle materials are 304 stainless steel and 316 stainless steel. 

Grade 304

grade 304 stainless steel contains 18% chromium (Cr) and 8% nickel (Ni) making it corrosion and oxidation resistant. It is often used in automotive trim, food industry equipment, storage tanks and piping.

Grade 316

Grade 316 stainless steel is known as marine grade stainless steel, which contains less chromium (typically 16-18%) and more nickel (10%-14%), and also contains 2-3% molybdenum, which allows it to withstand more extreme environmental conditions such as salt water, humidity and high chlorine levels. This makes grade 316 stainless steel shackles the perfect choice for marine and boat hardware.

Stainless Steel Shackle Body Styles

Stainless Steel Shackle Body Styles

Stainless steel bow shackles, which are bow-shaped and tend to be round and O-shaped, are also known as anchor shackles and can withstand loads from multiple directions and are suitable for supporting side loading and multi-leg slings. although the stainless steel sahckle does reduce its overall strength due to its larger loop design, it is able to handle larger straps.

Stainless steel D-shackles, shaped like a ''D'', this smaller loop design is primarily designed to withstand tension in a straight line and is suitable for straight pulling and should not be used for side pulling, where a side load would twist or bend the D-shackle. Therefore the center line of the load should always be aligned with the center line of the D shackle.

The stainless steel Snap shackle is a variant of the D-shackle which has a spring-activated mechanism and can therefore be used quickly and one-handed. It is suitable for applications that require frequent hooking or unhooking.

Stainless Steel Shackle Pin Variants

SS Shackle Pin

The stainless steel shackle pin is usually available as a screw pin, bolt-type pin, square head pin or slotted pin.

Square Head Pin

The square head pin is a common type of unloading pin used in the fishing and trawling industries.

Screw Pins

Screw pins have a scalloped end with or without a shoulder on one end and a threaded end on the other. These pins are easy to screw on and off, so it is not recommended that you use a shackle with these pins for long term or permanent applications.

Slotted Pins

Slotted pins are those with a slot at one end and need to be tightened or unscrewed with a one-touch reamer. The countersunk slotted pin is almost parallel to the shackle body and is ideal for the commercial fishing industry as well as architectural applications.

Bolt Type Pin

The Bolt type pin is a more secure pin than the screw pin and consists of a single threaded hexagonal bolt, a nut and a cotter pin. The bolt is passed through the shackle body and the nut is tightened. The cotter pin is passed through a small hole in the end of the bolt to prevent the nut from slipping off. With the tightening nut and cotter pin, there is no need to tighten the pin before lifting and moving the load, making the bolt type pin release buckle the best choice for long term or semi-permanent scenarios.
