The slotted cylindrical nut is a precision fastener with a cylindrical shape and a slotted head. The inner hole has a standard metric machine thread, and common sizes range from M2 to M10. This product can be manufactured from a variety of commonly used materials, including high-quality low-carbon steel, medium-carbon steel, alloy steel, 304 stainless steel, 316 stainless steel, brass, and aluminum alloy. It can also be customized with various surface treatments such as environmentally friendly blue-white zinc plating, color zinc plating, black zinc plating, environmentally friendly nickel plating, zinc-nickel alloy plating, Dacromet coating, electrophoresis, PVD, stainless steel natural finish, and stainless steel passivation to meet the requirements of different applications. In terms of strength grades, carbon steel materials can reach 4.8, 6.8, and 8.8, while stainless steel materials offer options such as A2-50, A2-70, A4-70, and A4-80. Non-ferrous metals have a strength grade of at least 4.8. This nut has a compact structure, is easy to install, and is widely used in mechanical equipment assembly, home appliance fixing, communication equipment assembly, electronic equipment housing installation, and precision instrument fastening. It is a commonly used product among customized fasteners.
We support customized production based on customer-provided drawings or industry standards.
