To what depth should flooring screws be counter sunk?

Counter-sinking flooring screws is important to ensure a clean and professional finish, as well as to prevent issues with the flooring over time. The recommended depth for counter-sinking flooring screws is typically around 2mm. This depth allows the screw head to sit just below the surface of the flooring material, providing enough room to fill with putty or a matching material if desired without compromising the structural integrity of the flooring.

Counter-sinking at this depth also helps in minimizing the risk of damage to the surface by preventing protruding screws that could cause wear or snagging. While a slightly deeper sink might be suitable in some circumstances, going too deep can present challenges during installation, such as weakening the connection or causing uneven surfaces. Thus, 2mm strikes a good balance for both functional and aesthetic considerations in proper flooring installation.
