An SDS Wafer Head Screw is a low-profile fastener with a cylindrical, flat-top wafer-style head designed for high-torque mounting in tight spaces. It's commonly used in electronics, automotive, and aerospace assemblies. These screws are removable and reusable and are installed with machine-driven insertion to speed up assembly.

Key features include a low head height for tight clearances, wafer-like sides to maximize contact area, a multi-drive system for a secure grip, and the ability to be removed and reused without damaging threads. They are also designed for quick, machine-driven insertion to improve throughput.

SDS Wafer Head Screws are offered in a variety of materials, including stainless steel, brass, and aluminum, providing options for strength, corrosion resistance, and weight depending on the application.

Yes. They are designed to conform to SAE and DIN standards, which supports compatibility and quality expectations across different industries and regions.

They are ideal for high-torque fastening in tight spaces, making them suitable for electronics enclosures, automotive assemblies, and aerospace hardware where a compact head and reliable torque are important.

1) Select the appropriate size and material for your application. 2) Use a compatible multi-drive driver for the screw’s drive interface. 3) Align the screw and apply machine-driven insertion with controlled torque until seated. 4) Verify the head seating and secure fit without over-tightening.

Use the appropriate driver to back the screw out slowly, ensuring you maintain straight alignment to avoid cross-threading. If threads are damaged, replace the screw to maintain a secure connection and consistent torque.

SDS Wafer Head Screws come in a range of diameters and lengths to fit different panel thicknesses and assemblies. They also feature a low head height to fit into tight spaces, with a cylindrical head and wafer-like side profile. Availability of specific sizes depends on the catalog.

The multi-drive system supports multiple common drive interfaces, enabling use with a variety of drivers. Always use the recommended bit type for the specific screw size to ensure a secure and undamaged installation.

Follow standard workshop safety practices and torque guidelines to avoid over-tightening. Ensure surfaces are clean and free of debris before installation. Use appropriate PPE as needed and verify seating after installation to prevent loosening in operation.

Choose based on environmental exposure and performance needs: stainless steel for corrosion resistance and strength, brass for good machinability and decent corrosion resistance in non-extreme environments, and aluminum for light weight and cost-sensitive applications. Consider factors like temperature, chemicals, and load when deciding.
