Hex Head Self-Drilling Screws

Description

Stainless steel hex head self-drilling screws are designed for fast, efficient fastening in metal-to-metal and metal-to-wood applications without the need for pre-drilling. Made from high-quality stainless steel such as SS304 or SS410, these screws offer excellent corrosion resistance, making them ideal for outdoor and high-moisture environments such as roofing, steel framing, and HVAC installation. The hexagonal head allows for high torque driving using standard tools, ensuring secure and stable fastening. Many hex screws come with bonded EPDM washers or other customized washers to provide a weather-tight seal and prevent water leakage.

Specification

Diameter: ST4.2, ST4.8, ST5.5, ST6.3
