Wichard HR D Shackle 16mm High Resistance

Exceptional strength in a compact forged stainless-steel shackle: 6,800 kg Working Load and 19,000 kg Breaking Load.

The Wichard HR D Shackle Ø16 mm #11208 is designed for applications where ordinary marine hardware simply isn’t enough.

Manufactured from forged High Resistance stainless steel, this professional D shackle combines impressive mechanical strength with compact dimensions and a relatively low weight.

For nautical applications, Wichard specifies a Working Load of 6,800 kg, while its Breaking Load reaches an impressive 19,000 kg.

HR – High Resistance Stainless Steel

The HR designation is one of the most important reasons to choose this Wichard shackle.

Wichard’s HR shackles are manufactured from 17-4 PH high-resistance stainless steel. Wichard’s operating documentation identifies its HR material as hardened martensitic stainless steel AISI 630, the designation corresponding to 17-4 PH.

The result is exceptionally high mechanical strength for the size of the fitting.

According to Wichard, one shackle forged from HR 17-4 PH stainless steel can be up to 60% more resistant than a comparable shackle manufactured from 316L stainless steel.

Forged for Demanding Loads

The #11208 isn’t simply formed from stainless steel. It features forged construction.

For marine equipment expected to handle substantial loads, this is a significant characteristic. Wichard combines its forging expertise with high-resistance stainless steel to produce a shackle offering outstanding strength in relatively compact dimensions.

The result is marine hardware designed for users who need clearly specified load performance rather than simply choosing a fitting based on its diameter.

16mm Diameter

The Wichard #11208 has a nominal diameter of:

Ø16 mm

This makes it a substantial step up from smaller HR shackles while retaining the compact geometry of a traditional D shackle.

When selecting the shackle, both the 16 mm diameter and its complete dimensions should be checked against the eye, block or other fitting to which it will be connected.

6,800 kg Nautical Working Load

For nautical applications, Wichard specifies:

Working Load: 6,800 kg

This is the working-load figure relevant to the product’s marine application.

It gives the #11208 serious capacity for demanding sailing and marine installations where significantly higher loads need to be accommodated.

Massive 19,000 kg Breaking Load

The Wichard HR D Shackle 16mm has an impressive:

Breaking Load: 19,000 kg / 19 tonnes

That is one of the strongest selling points of the #11208.

A breaking load approaching 19 tonnes from a 16 mm shackle demonstrates exactly why Wichard’s HR construction is used when a high strength-to-size ratio is required.

It is important, however, not to confuse Breaking Load with Working Load. The breaking figure is not the permitted everyday working load.

Working Load vs Breaking Load

For nautical applications, the two important values are:

The Working Load is the figure specified by Wichard for nautical applications, while the Breaking Load represents the load at which failure occurs under the manufacturer’s test criteria.

Always select marine hardware according to the appropriate working load, application and installation—not simply by its ultimate breaking strength.

3,800 kg WLL for Industrial Applications

Wichard also specifies a Working Load Limit (WLL) for industrial applications.

For the #11208:

Industrial WLL: 3,800 kg

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

19,000 kg ÷ 5 = 3,800 kg WLL.

So the three figures should be clearly distinguished:

Nautical Working Load: 6,800 kg
Industrial WLL: 3,800 kg
Breaking Load: 19,000 kg

D-Shackle Design

The classic D-shaped profile provides a compact connection point for compatible marine hardware.

This geometry is particularly appropriate when loads are correctly aligned with the main axis of the shackle.

Correct installation matters. A shackle’s strength rating should never be interpreted independently of the direction of load, compatibility of the connected components and intended application.

Detailed Dimensions

The Wichard #11208 dimensions are:

Diameter: 16 mm
A: 56 mm
B: 32 mm
C: 16 mm
D: 32 mm
Pin diameter: 16 mm
E: 16 mm
F: 96 mm
G: 87 mm

Checking these measurements before ordering helps ensure that the shackle will fit correctly with the intended block, eye or other attachment point.

Only 464 g

Despite its 19,000 kg Breaking Load, the Wichard #11208 weighs only:

464 g

This impressive strength-to-weight ratio is one of the main advantages of the HR design.

For performance-oriented sailing and professional marine installations, reducing unnecessary hardware weight while maintaining high load capacity can be an important consideration.

Suitable for High-Load Marine Applications

The Wichard HR range is designed for applications where high mechanical loads are a priority.

The #11208 is particularly relevant for suitable:

• Sailing hardware
• Yacht hardware
• Rigging applications
• High-load attachment points
• Blocks and compatible fittings
• Professional marine installations
• Performance sailing
• Racing yachts

The correct shackle should always be selected according to the specific load case, geometry and equipment manufacturer’s requirements.

HR 17-4 PH vs 316L Stainless Steel

Both materials are used extensively in quality marine hardware, but they serve different engineering priorities.

The key advantage of Wichard’s HR 17-4 PH construction is mechanical strength.

Wichard states that a forged HR shackle can provide up to 60% greater resistance than a comparable 316L stainless-steel shackle.

For users selecting hardware primarily around high-load capability and strength-to-size ratio, this makes the HR range particularly attractive.

CE Marked for Industrial Applications

Wichard’s shackle documentation identifies these shackles as lifting accessories for applicable industrial use and specifies CE marking in accordance with the Machinery Directive 2006/42/EC.

For industrial applications, the manufacturer’s specific WLL and operating instructions must be followed.
