Introducing the ELCO BI-FLEX® 1/4-20" x 3" 3-Point Phillips Undercut Flat Head Self Drill Screw, a high-performance fastener designed for durability and reliability. These screws are perfect for a wide range of applications, from woodworking to metalwork, thanks to their exceptional strength and ductility. With a 100-count package, you'll have everything you need to tackle your next project with ease.

Key Features and Benefits

The ELCO BI-FLEX® self-drilling screws are engineered with cutting-edge technology to provide superior performance. High strength, ductility, and reliability make them a top choice for professionals and DIYers alike. These screws are immune to hydrogen-assisted stress corrosion cracking (HASCC), ensuring long-lasting performance even in harsh environments. Additionally, they offer higher corrosion resistance compared to carbon steel and 410 series stainless steel fasteners, making them ideal for use in dissimilar metal applications, including connections involving aluminum.

Specifications and Uses

The ELCO BI-FLEX® self-drilling screws come with a Stalgard GB coating, which creates greater galvanic compatibility in dissimilar metal applications. This coating is particularly beneficial for connections involving aluminum. The screws are 18-8 stainless compatible with pressure-treated lumber, making them a versatile choice for various building projects. With a package quantity of 500, these screws are perfect for large-scale construction or for those who prefer to stock up. Whether you're working on an interior or exterior project, the ELCO BI-FLEX® self-drilling screws are a reliable and efficient choice.
