Abstract (en)
The invention relates to a method of making a fixing cramp comprising a bolt-shaped nail (1) and a tubular sleeve (4) which fixing cramp can be incorporated in concrete when said concrete is being poured. Such cramps are used in large numbers. It is important to keep the cost price of such cramps as low as possible, and to achieve a maximum the load-bearing capacity of the fixing cramps. The bolt-shaped nail (1) is made by means of the tools and in accordance with the method used for producing hexagonal head bolts, whereby the forming of the hexagon is not carried out for the fixing cramps. The head (3) is substantially cylindrical, and it has a diameter which is at least twice that of the nail shank (2). <IMAGE>
