Abstract
A hoist ring for fixed engagement, in a mounted position, in a threaded bore on a load surface of a load member includes a load bearing ring, a support member and a post. The support member has a cylindrical passage having a first axis and further includes a ring slot to pivotally support the load ring and allow the load ring to rotate about a second axis perpendicular to the first axis such that the load ring freely adjusts to the direction of an applied force. The post has an unthreaded portion in the passage and the passage and the ring slot intersect for the unthreaded, portion of the post to interengage with the load ring to retain the load ring in the ring slot when the post is received in the passage.
