We need to find reliable supplier for hinges with plastc expandible pins as shown in the picture. These pins are enlarged by one single turn of a machine operated screwdriver, so not manually. Therefore we dont consider screws that need hand operated screwdriver. If interested please reply and will send you details regarding complete hinge (including plate) and quantities. Also we give priority to companies that can arrange shipment of sets of 3 or 4 hinges in one plastic bag.
