Abstract: A fastener, to be inserted into a receiving hole in a panel, has a cylindrical body with a longitudinal axis and a straight bore through the body with an axis that is inclined relative to the axis of the body. In another type of fastener, the fastener has a body formed of cylinders that are joined end-to-end and have axes that are inclined relative to each other. One cylinder is a right cylinder. A straight bore passes through both cylinders such that the bore axis is aligned with the right cylinder. Generally, the axis of the straight bore is perpendicular to the panel surfaces and the axis of the inclined cylinder is inclined at between 5.degree. and 60.degree. relative to the bore axis. The axis of the receiving hole is aligned with the axis of the inclined cylinder. When the fastener is inserted into the panel, the inclination of the receiving hole cooperates with the fastener body to prevent rotation and provide an axial holding force when a fastener bolt is threaded into the fastener.

Abstract: A fluid connector fitting nut lock includes a sleeve that fits down over the nut and that has an integral locking mechanism to fix the sleeve in a raised position that allows the nut to be turned and in a locked position that prevents the nut from backing off due to vibration or other external forces. The integral locking mechanism eliminates the need for a separate lockwire or clipwire.
