Abstract: A spacer element which is designed at both ends for the attachment to a sheet metal part or to a hollow section for the formation of a component assembly and which optionally has a fastener section with an internal thread or external thread for the attachment of a component to the component assembly by means of a screw or a nut, is characterized in that the spacer element is not deformable or at least substantially not deformable on attachment to the sheet metal part or to the hollow section and in that the spacer element is provided at both end faces with respective undercuts for the form-fitted reception of sheet metal material or of the wall material, whereby the spacer element is secured to the sheet metal part or to the hollow section and preferably also secured against, rotation. Various variants, component assemblies and methods are likewise described and claimed.

Abstract: A lock washer includes a planar washer body formed of a sheet of resilient metal having a selected thickness no less than the pitch thread of the bolt with which it is to be used. First and second lock tabs integral with the body extend radially outward of the central aperture, wherein each of the tabs has a radially inward facing, straight, free edge transverse to a radius of the body, and each of the tabs is displaced by a spring bend to one side of the plane of the body. The washer body is etched to a selected lesser thickness in the area of the spring bend to provide a selected spring force when the tab is pushed down to the plane of the body.

Abstract: The locking nut and bolt system utilizes a bolt with thread having a plurality of notches generally longitudinally spaced in a predetermined pattern. Each notch has a lock face and an opposing slope. The locking unit carries one or more tines. The tine has a distal tine end adapted to latch onto the lock face of the notch on the bolt and, when the distal tine end is not disposed in one or more notches, the tine end moves on the bolt thread crest. When the distal tine end is in the notch or notches, the lock face of the notch prevents counter-rotational movement of the bolt with respect to the nut when the distal tine end abuts the lock face. The locking unit supports the tine and may be cylindrical, rectangular or on a perpendicular support face normal to a radial plane through the axial centerline of the nut thread. The locking unit may be on a nut insert or may be carried on the leg of a U, J or S-shaped clip. The locking unit may be recessed as a blind hole.

Abstract: An attachment system, which is to be introduced in a mounting opening (5) of a hollow body (3), includes a rear engagement member (4) for engaging from behind holding projection (17.1, 17.2) of the hollow body (3), at least one stop (6, 37) for engaging edges of outer sides of the hollow body which limit the mounting opening (5) and connected with the rear engagement member (4) by a screw, and a device providing for a relative rotational movement between the stop (6) and the rear engagement member (4) about an axis of the fastening means (7; 35) and formed as a transformation device (9; 31) for converting a translational movement of the screw (7; 35) relative to the stop (6) in a rotational movement of the rear engagement member (4) relative to the stop.

Abstract: A device 10 for a receptacle secured to a substructure is provided. The torque arm has a first portion 11 and a second portion 18, formed integral and substantially normal to the second portion, so as to provide a load transferring mechanism which prevents rotation of the receptacle as a torque load is applied. The torque arm 10, secured adjacent the substructure is constructed so as to allow use within a range of adjustment as determined by the distance from the substructure end edge 27 to the center of the opening in the substructure 24.
