Sound Absorbing Drywall Screws Sound Fastener 4.2 × 35 mm (1 pcs.)

Sound Fastener screws are an innovative solution designed to reduce noise and vibration transmission through walls and ceilings. These screws are specifically engineered to provide a flexible connection between drywall panels and wooden frameworks, effectively minimizing sound wave propagation. Thanks to the unique design featuring a double head and integrated spring, the screws create a 1 mm gap between the drywall and wooden structure, which helps absorb both airborne and impact sound.
