Brass Screw and Nut Combination Screw

Brass screw and nut combination screws are a common type of pre-assembled fastener, consisting of a brass Phillips or slotted screw and a brass hexagonal nut pre-assembled. They are shipped with the screws already fitted together, eliminating the need to find the nut separately. This assembly conforms to national standards (GB/T 9074.1) and German standards (DIN 964), and is indispensable in applications requiring high conductivity, corrosion resistance, and rapid assembly, such as electrical terminals, instruments, lighting assemblies, and marine fittings. It provides reliable fastening and anti-loosening. To enhance the conductivity and rust resistance of the assembly, we can polish or treat the brass screws with an anti-oxidation process, or thicken the nuts to increase locking strength. This also improves the anti-loosening performance of the assembly under vibration.
