Tek screws, also known as self-drilling screws, are a type of fastener commonly used in construction and manufacturing. With their unique design, tek screws are able to drill their own holes and secure materials without the need for pre-drilling.

In the United States, ASTM (American Society for Testing and Materials) standards define the specifications for shear studs. For instance, ASTM A108 has specifications for carbon steel shear studs, which are often used due to their strength and ease of welding. The tolerances for size are usually specified to ensure consistency in performance and reliability in construction.

The materials used in the manufacturing of these studs vary widely, incorporating options such as stainless steel, carbon steel, or specialized alloys, depending on the required strength, corrosion resistance, or temperature tolerance. The threads can also be customized to different specifications, such as coarse or fine pitch, to suit specific applications.
