A screw pin anchor shackle can be a very useful tool when lifting a heavy load. You may wonder how tight your screw pin anchor shackle should be as you lift a load. Read on to find the answer so you can keep your loads and your team safe and secure.
When Do I Use Screw Pin Anchor Shackles?
You would use screw pin anchor shackles for temporary or quick-connect applications rather than long-term or permanent ones. You can use the anchors when changing slings and other hardware or in applications involving multi-leg assemblies, static loads, or side loading.
How Tight Should I Make Them?
If you’re wondering how tight your screw pin anchor shackle should be, we’ll tell it to you straight: very tight. Even though you should only use the shackle for temporary applications, securing the shackle is not any less important.
As you tighten the shackle, fully engage the pin threads with the shackle’s ear. The pin’s shoulder should have contact with the shackle’s body.
How Can I Tighten the Shackle?
The pin unthreading itself and causing a major accident is the last thing you want to happen when using a screw pin anchor shackle. Before lifting a load, tighten the pin with your hand at the very minimum. We recommend securing the pin with “mousing” in order to prevent the pin from loosening. In this process, you put an iron wire through the hole in the pin’s collar, wrap it around the other leg of the shackle, and tie both ends together. This will allow the pin to hold the load for longer, and you will avoid accidents or injuries on your site.
