I know these cost more than the imports. If you need these to perform, trust no other. These are 100% USA made forged & tested. Threads on bolt & nut are deep, and mate well, no slop. It’s apparent they are cut from full diameter rod & not cast threads like import.
The imports have a lot of slop / between nut & bolt (nut wobbles on the threads). The imports nut & bolt only start to grab the threads 1/2 way up the threads, where as the Crosby engage instantly, right at the beginning of the thread, full contact with Crosby. Quality is consistent between Crosby shackles. Imports are sometimes mis shaped, porous surface. I work in the oilfield, many crane & fork lift loads moved daily. Not a single failure from a Crosby shackle.
