5.5mm (No.12) x 55mm (2.1/4") Self Tapping Hex Socket Cap Head Screw, A2 Stainless Steel

5.5mm (#12) x 55mm (2.1/4") - Self Tapping Hex Socket Cap Head Screw - A2 Stainless Steel | Vital Parts - STHSC-5.5-55-A2

Self Tapping Hex Socket Cap Head Screws are an essential component for a variety of fastening applications. These screws are designed to create their own threads when driven into materials, eliminating the need for pre-tapping. This self-threading ability makes them a highly efficient choice for professionals and DIY enthusiasts alike.

Manufactured from high-quality A2 stainless steel, these screws offer exceptional corrosion resistance, making them ideal for use in indoor and outdoor environments. Additionally, an A4 stainless steel variant is available for enhanced resistance to harsher conditions, such as marine and industrial environments.

Why Choose Self Tapping Hex Socket Cap Head Screws?

These screws provide a strong, secure and reliable fastening solution for materials where traditional screws may not offer adequate grip. Their self-tapping nature means they efficiently cut and form their own threads within the substrate, reducing the need for additional threading tools or preparatory work. This speeds up the installation process and reduces the risk of errors.

The hex socket cap head design allows for increased torque application without the risk of cam-out, a common issue with Phillips or slotted head screws. This makes them an excellent choice for applications requiring precision and secure fastening.

Installation Tip:

For best results, a pilot hole is recommended when installing these screws. The ideal size of the pilot hole depends on both the material type and its thickness. A properly sized pilot hole helps to ensure a secure fit while preventing material damage.
