Our stainless steel type 316 shackles are made with quality in mind. Type 316 stainless steel contains the element molybdenum which gives the stainless steel higher corrosion resistance and a particularly higher corrosion resistance to pitting and crevice corrosion in high chloride environments. The screw pin d shackles are precision cast with a standard pin. This means the pin is able to be removed from the body of the shackle. We also sell captive pin screw pin d shackles in stainless steel.
