A METHOD of fastening which can ri save time and cost has been introduced by the Armstrong Patents Co. Ltd., Eastgate, Beverley, Yorkshire. It offers a permanent fastening between fixtures and/or mating components in cast iron, steel, or any non-frangible material— without reaming or tapping.
Known as the Nose Cone Wej-It, the fastener is available in five different designs, and is a development of the larger Wej-It Retraction Bolt which was recently introduced. The principle of the fasteners is simplicity. No special tools or equipment are required; the material to which the fixture is to be fastened is drilled and the Wej-It is pushed into the hole. As it is pulled back, spring-loaded " shovels" clamp against the sides of the hole. The result is a fastening which is permanently anchored and cannot be loosened.
