Fischer 573428 Concrete screw 85 mm Hex head 100 pc(s)

This sheet metal screw is designed to form a secure mechanical connection when driven into masonry or structural substrates. Installation relies on the hex drive to transmit torque and draw material together while the threaded shank bites into the host medium; the screw’s length enables through-fixing or deep embedment depending on application. The stainless composition and corrosion-protected finish help maintain performance where moisture or contaminants are present. Typical use includes fastening metal components to concrete or masonry in construction and industrial settings, where consistent torque transfer and long-term serviceability are required.
