Single End Male Stud (SEMS) screws are commonly used in the auto and electronics industries, amongst others. These screws come with a screw and a washer already attached. This makes them easy to use and perfect for applications that need to be taken apart often. SEMS screws come with different kinds of heads, like pan, flat, and hex. They are also made of different materials such as brass, steel and stainless steel.

Shoulder screws made to a high level of precision are perfect for high-precision uses like those in the auto, aerospace and defense industries. The cylindrical shoulder on these screws makes it easy to fit and line up what is being fastened. Classic Fasteners can source precision-grade shoulder screws in the sizes and thread types, as well as materials like titanium and stainless steel, that you need.

Shoulder screws for commercial use are made the same way precision shoulder screws are, but they are used in less demanding situations. These screws are often used in consumer products, as well as in the industrial and auto industries. They come in different sizes and thread types, as well as different materials like brass, steel, and aluminum.

Weld screws are made to be used in joints that are welded together. They have a threaded shank that can be welded to a base material to make a strong, permanent connection. Weld screws are often used in the automotive and building industries. They come in different sizes and thread types, as well as different materials like steel, stainless steel, and aluminum.

Projection weld screws look like weld screws. They do, however, have a small projection on the shank that melts and joins with the base material during welding. This makes a safe and permanent connection. Projection weld screws are often used in the automotive and appliance industries. They come in a variety of materials, like steel, stainless steel, and brass, as well as sizes and thread types.

Square drive screws are designed to be used with a square-headed driver, providing a more secure and efficient connection than traditional slotted or Phillips head screws.
