Abstract: A device is disclosed for removing a nut frozen is place regardless of the degree to which the corners of the nut have been rounded by a prior attempt to remove such nut by an ordinary wrench. The device is formed with an opening, which is sized to receive the nut and formed with a plurality of teeth preferably arranged such that a leading or cutting edge of each tooth engages approximately with a midpoint of a flat of the nut. The front and rear faces of each tooth form an angle of less than 90.degree. and a gullet between teeth, which is defined by a rear face of one tooth and a front face of a next adjacent tooth, is sized to freely receive the corner(s) between the flats with which the leading edges of an adjacent pair of teeth engage. The gullet is shaped and sized to permit the formation of a chip upon penetration of a leading edge into a flat of a nut, which is operable to lock the nut for rotation with the device.

Abstract: An improved hasp construction is disclosed for use in releasably securing a pair of adjacently disposed closures in a closed condition relative to a closure bounding frame; the hasp including a first plate secured to one of the closures and a second plate hingedly mounted on the first plate for movement between an operative position in which it overlies the second closure and cooperates with a frame mounted staple to releasably secure both of the closures in their closed condition and inoperative position in which it is removed from cooperative association with the staple and arranged to overlie the first closure to permit selective opening movements of the closures relative to one another and the frame.
