Abstract: An electronic device has a screw nut. The screw nut is configured for fixation of a fastener. The screw nut includes an inner nut component, a cushioning component, and an outer nut component. The inner nut component has a screw hole portion configured for fixation of the fastener. The cushioning component is sleeved on the inner nut component. The outer nut component is sleeved on the cushioning component. The cushioning component is connected between the inner nut component and the outer nut component so that the inner nut component is movably connected to the outer nut component.

Abstract: A connection between at least a first component A and a second component B with an attachment arrangement with tolerance compensation between the first component A and the second component B. The entire connection is fixated via a blind rivet which is not non-destructively detachable while a compensating sleeve spans a distance between the first component A and the second component B.

Abstract: An assembly is provided that includes a first fastener element and a second fastener element. The first fastener element is secured to the second fastener element with bonding material. The first fastener element may be a spacer such as a washer. The second fastener element may be a fastener or a washer.

Abstract: An expansion anchor includes an anchor bolt and an expansion sleeve which encompasses the anchor bolt. The anchor bolt has an expansion-sleeve expansion region and an expansion-element expansion region. The expansion sleeve has an expansion element which is disposed on the expansion sleeve. The expansion sleeve is radially displaceable by the expansion-sleeve expansion region and the expansion element is radially displaceable by the expansion-element expansion region. The expansion element is disposed on the expansion sleeve on a side of the expansion sleeve that radially faces the anchor bolt.

Abstract: [Problem] The purpose of the present invention is to provide an anti-loosening metallic male screw that can exhibit a sufficient anti-loosening effect by forming a flat part and a short slope in a part of the thread bottom of the male screw and thus ensuring pressure contact between a thread peak of a female screw and the slope at the thread bottom of the male screw.

Abstract: An anti-tampering device includes a housing with a bolt channel and a lock channel. The lock channel is aligned with, intersects and is perpendicular to the bolt channel. A head of a bolt and a portion of a shank of a bolt is received in the bolt channel. A lock received in the lock channel extends into the bolt channel, in proximity to the shank of the bolt, when the lock is in a locked position. The portion of the lock extending into the bolt channel prevents removal of the head of the bolt from the bolt channel.
