Description
Stainless steel anchor shackle designed for the job:
- A flush hex head allows for smooth passage through the bow roller
- A socket wrench or a crescent wrench could be easily used to open or close the pin even after many months of use
- A hole in the hex head is designed to safety wire the pin to prevent pin loosening
- Mantus shackles are forged and use high quality 316 stainless steel
- 1/4 Stainless Steel Shackle currently is not hex, but still features a standard pin design
Galvanized anchor shackles with Breaking Strength six times the working load limit:

- When sizing a stainless steel shackle for your anchor and Grade 30 galvanized chain, pick a shackle one size larger than the chain and the shackle will be the same strength as the chain.
- When sizing a stainless steel shackle for your anchor and Grade 40 galvanized chain, only a shackle one size larger will fit and the shackle will be 60 – 70% the strength of the chain, we recommend to using a mantus swivel to match the strength of the shackle connection to that of the Grade 40 chain.
