Product details

Discover HELPMATE quick-build screws. The black phosphating provides effective corrosion protection against short-term moisture exposure, making them ideal for construction or transport and perfect for adhering joint compound.

With a fine self-tapping thread, these screws allow for effortless insertion into metal without requiring significant force. The trumpet head ensures a flush, smooth sink of the screw while protecting the surface of the drywall.

Thanks to the sharp tip, no time-consuming pre-drilling is necessary, making the application particularly efficient. They are ideal for securing drywall to metal frameworks. For fastening to wooden substrates, our quick-build screws with coarse threads are suitable. Rely on HELPMATE for top-quality quick-build screws and simplify your construction projects.

Included: 1200 quick-build screws 3.9x45.
