Copper Screw

Copper screws are a common fastening element used in many residential and commercial applications and produced from an alloy of materials comprised primarily of copper and zinc, along with various other details such as aluminium, iron, and nickel. Copper screws were created with two goals: improved strength and corrosion resistance. Its highly resistant properties have made it ideal for outdoor use in areas exposed to constantly changing weather patterns and high humidity levels. The varying levels of each material used in the alloy result in dramatic variations in the required torque levels to ensure proper fastening. This allows for safer construction when utilizing copper screws vs traditional options, which require significantly higher torque levels, forcing strain on both the screw and the secured object.

Copper screws are an incredibly versatile fastening material, boasting applications in everything from HVACR and electrical to masonry and auto-repair. Their superior conductivity and corrosion resistance make them ideal for electronics, wiring, or marine uses. At the same time, their strong bond and hardness allow them to weather impacts while still being easy to remove. Copper screws' uniformity offers a consistent tightening torque that helps engineers craft precise repairs easily. Furthermore, their unique properties enable them to be put into conditions like temperature changes and harsh environments without risking damage. With their valuable properties and various applications, small copper screws are helpful for DIYers and professionals. The main uses of these screws are in shipping construction, manufacturing industries, electrical appliances, saltwater appliances and chemical areas.

FAQ's for Copper Screw

Copper machine screws are small, threaded fasteners designed to be used with tapped holes in metal, wood or plastic. They are made from high-quality copper material that offers excellent electrical and thermal conductivity and corrosion resistance. Copper machine screws come in various sizes and styles, including round head, flat head, pan head and more. They are commonly used in electrical applications where conductivity is essential, such as in manufacturing electronic devices, computers, and telecommunications equipment. Additionally, copper machine screws can be used for marine applications due to their resistance to saltwater corrosion.

Yes, copper screws are highly corrosion-resistant and can withstand exposure to many environmental conditions, including moisture and certain chemicals.

Standard sizes of copper screws are #6, #8, #10, 1/4", 5/16", 3/8" and 1/2". The threads per inch vary based on the size of the screw; the larger the diameter of the screw, the fewer threads per inch it will have. Our manufacturers can make it in any custom size, dimensions, specifications, and shape.
