Abstract

1. A method of casting-in inserts into a cylinder head (1, 1', 1"), in which holes (5, 5', 5") each serving to accommodate a respective cylinder head cap screw (4) are to be worked into the cylinder head (1, 1', 1") and into the inserts, in which each hole is provided with its respective insert, in which each insert is located at the respective hole's end facing the cap of the screw to be accommodated therein, is arranged substantially coaxially with the hole's axis, is made of a material different from that of the cylinder head (1, 1', 1"), and in which the cylinder head (1, 1', 1"), when being cast, will be cast around at least a part of each insert, characterized in that holding devices, one for each insert and securing the latter in a moulding box, extend along the direction of the respective holes (5, 5', 5") to be bored subsequently, and in that at least a section of each holding device has a diameter smaller than that of the respective hole so that, when the cylinder head is machined thereafter, each device will completely be bored out.
