Self Piercing Screws, Slotted Hex Washer Head, Zinc

Self-piercing screws, also known as self-piercing tapping screws, are a type of fastener designed to create their own holes and threads in relatively thin materials. These screws are commonly used to join two thin sheets of metal or other materials together without the need for pre-drilled holes or pre-tapped threads.

Self-piercing screws are commonly used in applications where two thin materials need to be joined together, such as in automotive manufacturing, HVAC systems, roofing, and other sheet metal work. They offer a fast and efficient method of attaching materials without the need for additional drilling or tapping processes.
