Stainless Steel Rigging Hardware
Stainless Steel Shackles
8 products
This category gathers stainless steel shackles for marine, architectural and general rigging: standard D shackles (SS910), long D shackles (SS9101), anchor or bow shackles (SS911), D shackles with square head and sink head pins (SS913, SS912), a twisted shackle (SS921), a stamped flat shackle (SS901) and a fixed snap shackle (SS450). All are AISI 316 except the SS901, which is AISI 304. Each product page carries its full size table, and the SS910, SS9101 and SS911 tables include breaking loads in kg. In the lifting market, shackles are generally expected to be rated and marked to standards such as EN 13889 or US federal specification RR-C-271; these stainless parts are listed as rigging hardware without such a rating. Power Honour can supply the range under a private label or to a customer drawing.

SS450SS450 316 Stainless Steel Fixed Snap Shackle
The SS450 is a fixed snap shackle in AISI 316 stainless steel, offered in three sizes with overall lengths of 52, 66 and 96 mm. Its plunger-locked jaw opens quickly by hand, which is why snap shackles are used on sailing halyards, sheets and spinnaker gear.

SS901SS901 304 Stainless Steel Stamped Flat Shackle
The SS901 is a flat shackle stamped from AISI 304 stainless steel, in seven sizes with a material thickness of 1.5 mm to 4.0 mm. Its flat body suits small, light connections on canvas, covers, straps and boat fittings.

SS910SS910 316 Stainless Steel D Shackle
The SS910 is a standard D shackle in AISI 316 stainless steel, offered in seven sizes from 5 mm (3/16 in.) to 20 mm (3/4 in.). Listed breaking loads run from 1300 kg to 18200 kg, and it is the general-purpose dee shackle of this stainless range for marine and architectural rigging.

SS9101SS9101 316 Stainless Steel Long D Shackle
The SS9101 is a long-type D shackle in AISI 316 stainless steel, in five sizes from 4 mm (5/32 in.) to 10 mm (13/32 in.). Its longer body leaves more room inside the shackle for thick eyes, toggles or several attachments, and breaking loads of 800 kg to 3200 kg are listed for the 4 to 8 mm sizes.

SS911SS911 316 Stainless Steel Anchor (Bow) Shackle
The SS911 is an anchor shackle, also called a bow shackle, made from AISI 316 stainless steel in six sizes from 4 mm (5/32 in.) to 12 mm (15/32 in.). Its rounded bow leaves room for several attachments, and listed breaking loads run from 750 kg to 7200 kg.

SS912SS912 316 Stainless Steel D Shackle with Sink Head Pin
The SS912 is a D shackle in AISI 316 stainless steel with a sink head (countersunk) pin, in five sizes from 7 mm to 12 mm. The pin head sits flush with the shackle ear, leaving less to snag sails, lines or fabric.

SS913SS913 316 Stainless Steel D Shackle with Square Head Pin
The SS913 is a D shackle in AISI 316 stainless steel fitted with a square head pin, in five sizes from 7 mm to 12 mm. The square head can be turned with a spanner or shackle key, giving a firmly tightened screw-pin connection for marine rigging.

SS921SS921 316 Stainless Steel Twisted Shackle
The SS921 is a twisted shackle in AISI 316 stainless steel, in six sizes from 4 mm to 12 mm. The 90-degree twist lets it join two parts that sit at right angles, such as a halyard and a sail head or a block and a fitting.

Frequently asked questions
- D shackle or bow shackle: which should I use?
- A D (dee) shackle has a narrow, straight-sided body suited to a single, in-line load. A bow or anchor shackle has a rounded body that leaves room for several attachments and copes better with loads at a slight angle, although side loading still reduces capacity. In this range SS910 is the D shackle and SS911 the bow shackle, with the same listed breaking loads in the 5 to 12 mm sizes.
- What does the breaking load (BL) figure mean?
- Breaking load is the force, here given in kg, at which the shackle is expected to fail. It is not a working load limit: the working load is found by dividing it by a safety factor appropriate to the application and any governing regulation. Where no BL is listed, the rating must be confirmed before use.
- Why choose a square head or a sink head pin?
- A square head pin can be tightened with a spanner or shackle key and is easy to secure with seizing wire, which suits standing connections. A sink head, or countersunk, pin sits flush with the shackle ear, leaving less to catch sails, lines or hands. SS913 and SS912 share the same body dimensions, so the choice depends only on the pin.
- What is a snap shackle used for?
- A snap shackle has a jaw held closed by a spring plunger that can be released quickly by pulling a ring or lanyard. It is used on sailboat halyards, sheets and spinnaker gear and on mooring lines. The fixed-eye SS450 is listed here, and swivel versions (SS451, SS453) are in the swivels category.
- Are stainless shackles suitable for lifting?
- Only if they are rated, tested and marked for lifting under the applicable standard or regulation. The shackles in this range have breaking loads for some sizes but no working load limits or lifting certification, so they should be treated as marine and rigging hardware. For lifting, specify a rated product and the documentation required.
- What should a shackle RFQ include?
- Give the product code, size and quantity per size, the material grade, the pin type and any marking such as size or grade stamps. If a breaking load must be verified, state the test method and the documentation expected. Private-label packaging and modified dimensions can be quoted against a drawing.
