Cross Recess Button Head Self-Drilling Screw 8-18x12-32 BUTTON Z/Y

Product Overview
Button head color zinc carbon steel self-drilling screw is a fastener specifically designed for efficient connection of metal sheets and light-gauge steel components, also commonly referred to in the industry as washer head self-drilling screw or large flat head wing screw.
It uses high-strength carbon steel as the substrate, with an environmentally friendly color zinc surface treatment process. The head features a button-type flat head design with an integrated widened flange, and the tail comes with a built-in, formed cutting edge. Without the need for pre-drilling, it can complete the three processes of drilling, tapping, and locking in a single operation, making it a widely used, efficient fastening solution in steel structures and renovation projects.

Product Applications
Building steel structures: Fixing of roofing/wall panels and purlins in color steel workshops, warehouses, and greenhouses.
Renovation and enclosures: Assembly of light steel keel suspended ceilings and partition walls, billboards, ventilation ducts, and cold storage panels.
Industrial scenarios: Fastening of metal components such as photovoltaic brackets, containers, and equipment cabinets.
