Our DIN 968 Washer Head Self-Tapping Screws are an innovative and highly efficient fastening solution, designed to streamline assembly by combining a screw and a washer into a single component. Also known as Wafer Head or PWA (Pan Washer Assembly) screws, they feature a large, flat-round head that provides a wide bearing surface, making them perfect for securing thin materials without the risk of pull-through. Manufactured primarily from corrosion-resistant 304 stainless steel, these self-tapping screws are ideal for a vast range of applications, including door and window installation, woodworking, sheet metal fabrication, and electronics assembly.
The standout feature of the DIN 968 screw is its integrated washer head. This design distributes the clamping force over a larger area, which is crucial when fastening soft materials like wood, plastic, or thin sheet metal. It prevents damage to the material surface and eliminates the need for a separate washer, saving time, reducing inventory, and simplifying the assembly process.
The self-tapping thread is designed to cut its own mating thread as it is driven into a pre-drilled pilot hole, ensuring a tight, secure fit. This makes them exceptionally versatile for use in a variety of materials. The standard material is 304 stainless steel, which offers excellent resistance to rust and corrosion, making these screws suitable for use in humid environments or outdoor applications. They are typically supplied with a polished finish that gives them a clean, silver-like appearance. With no minimum order quantity, we can support projects of any size, from prototyping to large-scale production.
