Screw pin shackles (also known as screw pin bow shackles) are designed to offer the security of a strong connection with the ease of a quick release pin. The bow shape has the ability to handle a wider variety of connections and multi-dimensional pulling, as opposed to chain shackles (also called D shackles) which have a more narrow profile and are meant to be used for straight line pulls.
The screw pin mechanism makes screw pin anchor shackles a good choice for temporary lifting jobs or those that require frequent connects and disconnects because the quick-release pin action is faster to attach and detach than a shackle with a round pin.
If you’re unsure if galvanized or stainless steel is right for your job, base your decision on the possibility of water exposure. While galvanized shackles do have a thin coating of zinc oxide to protect the steel from elements that lead to corrosion and oxidation, stainless steel offers more corrosion resistance, so it’s best for marine applications and other jobs where there’s a high concentration of water or moisture.
If there is a low chance of water exposure, galvanized is generally the more cost-effective option - this collection includes sizes ranging from 1/4" to 1-1/2" with working load limits from 1/2 ton to 17 tons.
