For swivel hoist rings, the threaded portion length is how many times the bolt diameter?

Explanation:
For swivel hoist rings, having a threaded portion length of 1.5 times the bolt diameter ensures enough thread engagement to safely transfer the lifting load. This length distributes the load across more threads, reducing the risk of stripping or pullout and accommodating minor misalignments. The other options provide too little or unnecessary extra engagement, which can compromise reliability or practicality.
