Wichard HR Bow Shackle Ω 16mm High Resistance

19,000kg Breaking Load, 6,800kg nautical Working Load and premium forged HR construction.

When a marine connection has to handle serious loads, the quality and mechanical performance of the hardware become critical.

The Wichard HR Bow Shackle Ω 16mm #11247 is engineered precisely for these demanding situations. It combines forged HR 17-4 PH stainless steel with a wide Bow / Ω profile, providing exceptional strength together with additional internal connection space.

HR – High Resistance Stainless Steel

The HR designation means High Resistance.

Wichard manufactures the #11247 from:

HR 17-4 PH Stainless Steel

This high-resistance stainless-steel grade is selected for applications where mechanical strength is a priority.

According to Wichard, an HR shackle can offer up to 60% greater resistance than a comparable shackle manufactured from 316L stainless steel.

This makes the HR range an excellent choice for demanding marine hardware applications where a high strength-to-size ratio is required.

Forged Construction for Serious Loads

The #11247 is a forged Bow Shackle.

Wichard states that its forging process helps provide outstanding working and breaking loads, as well as fatigue and corrosion resistance.

For sailors and marine professionals, this means a carefully engineered connection component designed specifically for demanding loads rather than simply a standard stainless-steel fitting.

Bow / Ω Shape – More Room for Connections

The Bow / Ω shape is more than a design detail.

Its wide, rounded body provides more internal room than a conventional narrow D shackle.

Wichard specifically recommends the #11247 when:

• The application requires high loads
• Ample room is needed
• Several lines or cables need to be attached

This combination of high strength and extra connection space makes the Ω geometry particularly versatile for suitable sailing and rigging installations.

16mm Diameter

The nominal diameter of the Wichard #11247 is:

Ø16mm

This 16mm construction delivers an impressive 6,800kg nautical Working Load and 19,000kg Breaking Load.

The result is a serious piece of high-performance marine hardware for applications where conventional lower-strength shackles may not provide the required capacity.

Nautical Working Load – 6,800kg

For nautical applications, Wichard specifies:

Working Load: 6,800kg

Wichard clearly identifies this Working Load figure as the rating for nautical applications.

That high load capacity is one of the main reasons to choose the #11247 for demanding sailing and yacht hardware installations.

Breaking Load – 19,000kg

The Wichard HR Bow Shackle 16mm reaches an impressive:

Breaking Load: 19,000kg / 19 tonnes

This exceptional breaking strength demonstrates the mechanical performance of the forged HR construction.

The Breaking Load must not be confused with the Working Load. The 19,000kg figure represents the breaking strength specified by the manufacturer and should not be treated as the normal permissible operating load.

Industrial WLL – 3,800kg

For industrial applications, Wichard specifies:

WLL: 3,800kg

Wichard clearly states that the WLL applies only to industrial applications and uses a safety factor of five against the Breaking Load:

19,000kg ÷ 5 = 3,800kg WLL.

The three important load ratings are therefore:

526g Weight

Despite its impressive load capacity, the #11247 weighs:

526g

A 19,000kg Breaking Load from a 526g component demonstrates the excellent strength-to-weight performance of Wichard’s forged HR construction.

For performance sailing and professional yacht hardware, keeping weight under control while maintaining high mechanical strength is an important advantage.

Bow Shackle Ω vs D Shackle

The difference between a Bow Shackle and a D Shackle is mainly in their geometry and available internal space.

A D shackle has a narrower profile and creates a more compact connection.

The Bow / Ω Shackle has a wider, rounded body, giving additional room inside the shackle.

For the #11247, Wichard specifically highlights the ability to attach several lines or cables and recommends the product where ample room is required.

So, when your installation needs high strength plus greater connection space, the Bow / Ω profile offers a clear practical advantage.

Designed for High-Load Applications

The Wichard #11247 is specifically recommended for applications requiring high loads.

Depending on the specifications and geometry of the installation, it is particularly relevant for applications such as sailing hardware, yacht hardware, rigging systems, performance sailing, high-load connection points and professional marine installations.

Always select the shackle according to the actual load, loading direction, connected equipment and installation requirements.

CE Marked

The Wichard HR Bow Shackle #11247 carries CE marking. Wichard also identifies the model for appropriate industrial lifting applications with an industrial WLL of 3,800kg and a safety factor of five relative to the Breaking Load.

Important – Not for Mooring

Despite the exceptional 19,000kg Breaking Load, Wichard explicitly states:

Do not use the #11247 for mooring applications.

A very high breaking strength does not automatically make a fitting suitable for every type of marine loading or installation. The manufacturer’s intended application and load specifications should always be respected.
