Wichard HR D Shackle 12mm High Resistance

10,000 kg breaking load in a forged 12 mm stainless-steel D shackle.

When a standard shackle isn’t enough, the Wichard HR D Shackle Ø12 mm #11206 is engineered for applications where considerably higher loads need to be handled.

Wichard manufactures this D shackle from forged HR 17-4 PH stainless steel, combining compact dimensions with outstanding mechanical strength.

For nautical applications, the Ø12 mm version has a working load of 3,600 kg, while its breaking load reaches 10,000 kg.

HR – High Resistance Stainless Steel

The letters HR stand for the high-resistance construction that differentiates this shackle from Wichard’s conventional stainless-steel shackles.

The #11206 is manufactured from:

17-4 PH High Resistance Stainless Steel

Wichard states that an HR shackle can offer up to 60% more resistance than a comparable shackle manufactured from 316L stainless steel.

This makes the HR range particularly interesting where high strength in compact dimensions is a priority.

Forged Construction

The Wichard HR D Shackle isn’t simply formed from stainless steel—it is forged.

Wichard’s manufacturing process heats the raw metal before shaping it under substantial force. Forging is fundamental to the company’s approach to producing shackles with high mechanical performance and reliability.

For demanding marine hardware, this manufacturing method is an important advantage.

3,600 kg Working Load for Nautical Applications

The official Working Load (WL) of the Wichard #11206 is:

3,600 kg

Wichard specifically identifies this Working Load value as the figure applicable to nautical applications.

That makes the 12 mm HR D Shackle suitable for demanding attachment applications where a conventional lower-strength shackle may not provide the required capacity.

10,000 kg Breaking Load

The Breaking Load reaches:

10,000 kg / 10 tonnes

This exceptional breaking load demonstrates the strength-to-size performance of Wichard’s HR construction.

It is one of the most important specifications to consider when comparing this shackle with conventional stainless-steel alternatives.

WLL 2,000 kg for Industrial Applications

It is important to distinguish between Working Load (WL) and Working Load Limit (WLL).

For the #11206:

Working Load – Nautical applications: 3,600 kg
WLL – Industrial applications: 2,000 kg
Breaking Load: 10,000 kg

Wichard explicitly states that the WLL applies only to industrial applications, such as lifting.

For industrial applications, Wichard calculates WLL using a safety factor of 5:

WLL = Breaking Load ÷ 5

Therefore:

10,000 kg ÷ 5 = 2,000 kg WLL.

Designed for High-Load Applications

Wichard specifically recommends the HR D Shackle for applications requiring high loads.

Typical uses include standard shackle applications and attachment applications involving suitable equipment such as blocks.

Its combination of high mechanical strength and relatively compact dimensions makes it particularly useful in demanding sailing and marine hardware installations.

Classic D-Shackle Geometry

The D shape is designed for attachment applications where loads are appropriately aligned with the shackle.

Compared with a bow shackle, the narrower profile provides a compact connection point for compatible marine hardware.

Correct load direction and sizing are essential when selecting any high-load shackle.

12 mm Diameter

The nominal diameter of the Wichard #11206 is:

Ø12 mm

Its main dimensions are:

A: 42 mm
B: 27 mm
C: 12 mm
D: 24 mm
Pin diameter: 12 mm
E: 13 mm
F: 72 mm
G: 68 mm.

These measurements should be checked carefully against the dimensions of the block, eye, fitting or other equipment to which the shackle will be connected.

Compact Strength – Only 192 g

Despite a breaking load of 10 tonnes, the Wichard HR D Shackle Ø12 mm weighs only:

192 g

This excellent strength-to-weight ratio is one of the key advantages of using high-resistance stainless steel for demanding marine applications.

CE Marked

The Wichard #11206 is CE marked. Wichard also provides an EU Declaration of Conformity for the product through its official documentation.

This is particularly relevant because the product’s specifications include both nautical Working Load and an industrial WLL.

Important: Not for Mooring

Although the Wichard HR D Shackle offers an impressive 10,000 kg breaking load, Wichard explicitly states:

Do not use for mooring applications.

High breaking strength alone does not make every fitting appropriate for every marine application. The shackle should always be selected and installed according to its intended use and the loads, geometry and equipment involved.

Technical Specifications

These figures are taken directly from Wichard’s official technical specifications for Part #11206.

HR Stainless Steel vs 316L

The material is one of the strongest reasons to choose this particular Wichard shackle.

Wichard identifies 17-4 PH as its martensitic High Resistance (HR) stainless-steel grade, while 316L is the austenitic stainless-steel grade widely used in marine hardware.

For the HR shackle range, Wichard states that the resulting shackle can be up to 60% more resistant than a 316L stainless-steel shackle.

The result is an excellent option when high mechanical strength is the primary requirement.

High Strength for Demanding Marine Hardware

The Wichard HR D Shackle, 12mm is built for applications where the connection hardware needs to withstand substantial loads.

With a 3,600 kg nautical Working Load and 10,000 kg Breaking Load, it delivers impressive strength from a forged component weighing just 192 g.

Its 17-4 PH HR stainless-steel construction, CE marking and proven Wichard forging expertise make it a premium choice for demanding attachment and high-load applications.
