A fastener apparatus and system for fastening an article through an opening in a mounting plate (501) includes a retaining nut (101) with a head portion (103) having a face surface (105), and a barrel portion (107) emanating from the face surface (105). The barrel portion (107) has a radially threaded surface (109) disposed on an interior portion (111) thereof commencing at a first position (113) proximate the face surface (105) and terminating at a second position (115) apart from the face surface (105). At least one longitudinal aperture (117) is disposed through a wall (119) of the barrel portion (107) commencing at the second position (115) and terminating at a third position (121), apart from the first position (113). The at least one longitudinal aperture (117) has a geometry that that relieves stress caused by force radially-applied to the head portion (103) of the retaining nut (101) when it is tightened around a mating threaded post.

Fastener apparatus and system with self-setting torque and over-torque

An electronic module assembly (50) has a bendable base plate (52) upon which circuit components (76) are mounted. A module enclosure device (56) mates with the base plate and has an integrally formed, non-removable support arm (96). During assembly, the base plate (52) is bent around the support arm (96) in a 'C' shape. Thus formed, the base plate (52) and the module enclosure device (56) form an internal cavity that holds the circuit components (76).
