What is the minimum depth of thread engagement for a 3/4 inch eyebolt into a steel object?

The minimum depth of thread engagement for a 3/4 inch eyebolt into a steel object is typically 1 1/8 inches. This depth ensures that the eyebolt is securely anchored, providing sufficient strength and load-bearing capacity when the eyebolt is subjected to tension. Proper thread engagement is vital for the safety and effectiveness of the lifting operation, as it minimizes the risk of the eyebolt loosening or failing under load.

Considerations such as stress distribution and the physical properties of the materials involved make this depth an accepted standard in lifting and rigging safety practices. Ensuring that the engagement meets or exceeds this minimum depth is critical for maintaining safety and preventing accidents during operation.
