Final answer:
Gutters are commonly joined using Tekscrews, which are self-drilling screws specifically designed for use in metal applications. The correct answer is B. Tekscrew.
Step-by-step explanation:
Tekscrews, self-drilling screws made especially for use in metal applications, are frequently used to join gutters.
Tekscrews have a sharp point that can easily penetrate the metal gutter material, and they have a coarse thread that provides a strong hold. They are typically made of stainless steel or zinc-plated steel to resist rust and corrosion.
To join gutters using Tekscrews, you need to align the gutter sections and position them correctly. Then, drill pilot holes through both sections of the gutter and insert Tekscrews into the holes. Finally, tighten the screws using an appropriate screwdriver or drill.
So, the correct answer is B. Tekscrew.
