Abstract
A spring nut for attaching a threaded object to a structure with reentrant lips. The spring nut can include a base, a first arm and a second arm extending from the base in a first direction, and legs extending laterally from the base. The arms can include a support portion, a structure-engagement portion, and a thread-engagement portion that can be configured to secure the threaded object against axial loading in a second direction opposite the first direction. Crumple zones in the support portions can deform upon loading of the threaded object in the second direction to cause the structure-engagement portion to be urged into the reentrant lips. Each of the legs can extend at a first angle from the base, toward the structure-engagement portions, to be disposed to contact an exterior surface of the reentrant lips of the structure when the first and second arms are received in the channel.
