Stainless Steel 316 Counter Sunk Shackle

Product Description

Stainless Steel 316 Counter Sunk Shackle

Stainless Steel 316 Counter Sunk Shackles are marine-grade stainless steel connection components designed for secure, corrosion-resistant performance in demanding marine and outdoor environments. Manufactured from 316 stainless steel, they are particularly suitable for boats, yachts, marinas, coastal installations and marine equipment exposed to moisture and saltwater.

The countersunk pin creates a smooth, low-profile finish with less protrusion than a standard shackle pin. This helps reduce the risk of snagging on ropes, sails, nets, clothing and surrounding equipment, making the shackle a practical choice where a clean, unobstructed connection is required.

Marine and boating applications

Stainless Steel 316 Counter Sunk Shackles are suitable for a wide range of boat and yacht rigging applications. They can be used for connecting ropes, cables, chains and compatible fittings, as well as securing deck hardware, sail fittings, covers, guard wires and other marine equipment.

They are also suitable for marina maintenance, pontoon equipment, mooring components, marine fabrication and coastal installations where a corrosion-resistant stainless steel shackle is preferred. The polished stainless steel appearance makes them suitable for visible fittings on leisure craft as well as practical commercial and maintenance applications.

316 stainless steel for marine environments

316 stainless steel is widely used for marine hardware because it offers improved resistance to corrosion in wet, coastal and saltwater environments. It is a suitable choice where standard steel or lower-grade stainless steel may deteriorate more quickly. However, no stainless steel is completely immune to corrosion, particularly when exposed to saltwater deposits, contamination, abrasion or contact with dissimilar metals.

Rinse and inspect the shackle regularly when used in saltwater or exposed coastal conditions. Check the body, pin and threads for wear, damage, distortion, cracking, pitting or corrosion. Remove the shackle from service if it is no longer in suitable condition.

Choosing the correct shackle

Select the correct size according to the rope, chain, cable or fitting being connected. If the shackle is being used for lifting or as part of a load-bearing system, confirm that it has the appropriate working load limit and certification for the intended application. Do not exceed the manufacturer’s stated capacity.
