<p>A rivet lug fixable to the bolt rod end passing through the inverted rail, and a pin unit located above the rail, are incorporated in a closing pin for fittings on windows and doors. On the part (3d) protruding from the rail (1), at least the rivet lug (3) has a thread, with the pin unit (4) screwed onto it with a counter thread. The pin unit has a threaded hole (4a) passing through it, for screwing in a tightening screw until it fits against the end face of the rivet lug. The screw may have an internal hexagon shape. The pin can be adjusted, regardless of its cross positioning, to regulate pressure, making it usable on widely differing frame profiles.</p> |
