The Crosby line of S-319 shank hooks come with an unthreaded shank so each hook can be threaded by the user for the application. Every hook has a pre-drilled cam so the corresponding latch can be installed. The S-319A is the old style alloy version of this hook which ranges from 30-300 ton working load limits.
