Now ive got your attention, i need some screws to fix my door handles on. The ones im looking for come in 2 parts, one end like a normal screw and the other half is like the female equivalent which has a screw head on but the male screw joins through the door and tightens into the female side. If you can follow that description then maybe you can help me out by telling me what this type of screw is actually called and where i can buy them. No joy in B and Q. Thanks
