Screw Pin Twisted Shackle is made in durable Type 316 stainless steel, and it is precision cast with a screw pin. The screw pin is popular because it is easy to connect and disconnect and can be removed from the body of the shackle. The screw pin shackle is twisted 90 degrees and is great for applications requiring a hook perpendicular to the shackle. Since this shackle is twisted 90 degrees, it can allow attachments from the side rather than the front of the shackle. This stainless steel shackle is made for durability as it contains Type 316, the most common type of stainless steel used in nautical applications, damp environments, or high chloride marine applications. The Type 316 grade contains molybdenum, which is made to prevent corrosive effects of salt water. Be sure to check the Working Load Limit (WLL) of the shackle to ensure it will work for your intended use. Always ensure the pins are straight and properly engaged, meaning the threads are fully engaged on the shackle. If the load shifts, the sling will unscrew the screw pin. Shackles should be inspected before each use. If you see bending on the body or pin, remove the shackle from use and dispose of it. As with all equipment with stated load limits, these strengths limits are based on proper use. Improper use will decrease strength and may cause the shackle to fail.
