High-Performance Thread-Cutting Screws for Thin Sheet Metal

Discover the ultimate solution for secure fastening in thin sheet-metal applications with our #12-24 Phillips Flat-Undercut Thread-Cutting Screws. Engineered for precision and durability, these screws are designed to offer exceptional thread engagement and a flush surface finish, making them ideal for shallow countersinks and tight spaces. Their unique undercut head design not only fits sheet metal as thin as 0.050" but also preserves full thread length for maximum strength. With a Type F cutting point and a bright-zinc electroplate finish, these screws are not just functional but also visually appealing.

Technical Specifications and Features

Our #12-24 Phillips Flat-Undercut Thread-Cutting Screws are crafted from heat-treated carbon steel, ensuring superior tensile and shear strength. The Type F cutting point taps clean internal threads in pre-drilled or punched holes, allowing for easy installation without the need for nuts. The Phillips #3 recess provides high torque with minimal cam-out, while the bright-zinc finish is RoHS-compliant and topped with a factory dry-wax film for consistent clamp load. Key features include a 82° flat-undercut countersunk head, a flush seating and drive design, and a bulk packaging that is perfect for HVAC skins, appliance frames, and OEM fabrication.
