Timco A2 Stainless Steel Tapping Screws, PZ Countersunk, 4.2x19mm (200 Pack)

The Timco A2 Stainless Steel Tapping Screws are designed for stitching metal or attaching components to metal surfaces, offering a secure and durable fastening solution. These high-quality screws require a pre-drilled hole for installation and are manufactured from A2 stainless steel (304-grade), providing ultimate corrosion resistance for long-lasting performance in harsh environments. Ideal for outdoor applications where moisture and corrosive elements are present, these screws ensure structural integrity and reliability.

The countersunk head design allows for a discreet finish, enabling the screw to sit flush with the surface when used in conjunction with pre-countersunk holes. This feature ensures a smooth and professional appearance while maintaining durability. The screws feature a 60° self-tapping thread for ease of insertion, reducing installation effort without compromising strength.
