Concrete screws

Different screwing-in methods are used for concretes of different density. When working with porous materials from the lightweight category, it is enough to mark the point, slightly deepen it, and proceed with a power screwdriver.

When working with heavy concrete, it is better to use the screw together with a plastic wall plug and pre-drilling of the hole.

Concrete screws look almost identical to regular wood screws, but have a number of features:

• Material — steel with the highest strength characteristics.
• Non-typical thread: it changes configuration along the entire length of the working shank. The variable thread pattern provides more reliable fastening in the concrete mass.
• Head recess — only in the form of a cross or star. A straight slot may not withstand the force when driving the screw into concrete. Variants with a hex or barrel head are also possible.
