RS PRO Self-Tapping Screw, Stainless Steel, Pan Head, Pozidriv, A2 Grade, Plain Finish, 13 mm Length, Thread Size 10, 521-658

The RS PRO 521-658 Self-Tapping Screw is engineered to provide robust fastening solutions for a wide array of assembly and installation tasks. With its pan head design, this screw offers a broad bearing surface that distributes the load evenly and ensures stable retention against the material surface. The Pozidriv drive enables effective torque transfer, simplifying the process of driving the screw and minimizing the risk of cam-out or stripping compared to traditional slot or Phillips heads.

Manufactured from high-quality A2 grade stainless steel, the screw is highly resistant to corrosion and oxidation, making it suitable for applications where cleanliness, durability, and hygiene are essential, such as food processing, commercial kitchens, and chemical facilities. The A2 alloy (also known as Type 304) is recognized for its general corrosion resistance in mild environments and provides a long service life even in demanding workspaces.

This thread-forming screw is designed to cut its own threads into softer materials without requiring a pilot hole, saving installation time and increasing the efficiency of assembly procedures. Its 13 mm length and No. 10 thread size offer compatibility with commonly used materials in woodworking, soft metals, and plastic assemblies. The plain finish not only supplies a clean aesthetic but also minimizes the introduction of contaminants, which is critical in sensitive industrial environments.

Complying with DIN 7981C standards, this screw delivers consistent performance and meets global fastener requirements. Its pan head shape is ideal for situations where the finished surface needs to be flush, while the Pozidriv recess greatly helps in reliable torque transfer during installation.

Applications for this screw include cabinetry, commercial furniture, machinery, HVAC panel installation, and any setting requiring a firm, corrosion-resistant fastener. It is widely used by carpenters, constructors, maintainers, and professionals working in food processing and laboratory environments due to its stainless construction and ease of installation. The screw’s design reduces the need for specialized pilot drilling, allowing quick and efficient fastening in most compatible materials.
