500 Timco 3.9x45mm countersunk self-tapping screws with self-drilling point for metal frames. Yellow zinc finish.
The Timco Countersunk Self-Tapping Screws are versatile fasteners designed for securing hardware to steel or aluminium-reinforced frames. These high-quality screws feature a self-drilling point, eliminating the need for pre-drilling and speeding up installation.
Constructed from durable carbon steel with a yellow zinc finish, these screws offer excellent corrosion resistance and longevity. The Phillips recess ensures easy driving with standard screwdrivers or power tools, while the countersunk head provides a flush finish for a professional appearance.
Ideal for window fabrication and various construction applications, these screws combine convenience with reliability. The self-tapping thread creates its own mating thread in materials like steel, aluminium, and certain plastics, making them incredibly efficient for assembly tasks.
