Abstract: A T-slot bolt sleeve for retaining the head of a conventional bolt in the T-slot of a machine tool table. The sleeve has a lower base block portion which slides in the main portion of the T-slot, and a neck portion which extends upwardly from this so as to ride in the relatively narrow entrance slot. There is a recess in the bottom of the base block for receiving the head of the bolt, and the shank of the bolt passes through a bore which extends upwardly from this. This holds the bolt in an inverted position so that the threaded end extends upwardly from the table for attachment of a nut or other fitting. The bottom of the base block is provided with a planar bearing surface which supports the assembly against side-to-side rocking as this is slid through the T-slot. The invention permits ordinary bolts of various lengths to be used in place of conventional T-nuts or T-bolts.

Abstract: A bolt head assembly comprises a circular bottom and a longitudinal straight walled section extending upwardly therefrom. Only the longitudinal section is threaded. A separate shank is threaded into an internal threaded portion of the bolt head. A washer and nut at the end of the bolt are used to secure a commode. In the event that the commode has to be replaced or any other exigency exists the shank can be easily removed from the head despite binding of the nut and washer to the bolt because of corrosion. Application of torque to the nut would cause the threaded shank to separate from the internal threaded portion of the head and be removed along with the nut and washer.

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: The attachment device comprises a C-shaped profile fitting and a clamping strap, inserted therein, with an inset screw. The mutually facing strips of the fitting are thickened on the inside towards the slot. The strap grips behind this thickening. Thus the limbs of the fitting are prevented from spreading apart. In order to secure the strap against displacement along the profile, it has transverse webs which penetrate with an edge into the thickenings when a nut is tightened on the screw and thus produce a positive connection between the strap and the profile even in the longitudinal direction of the profile. The attachment is suitable, above all, for the underfloor attachment of appliances to rail vehicles.
