Strong-Point's #8 x 2-1/2 in. Phillips Modified-Truss (R/W) Fine-Thread Self-Drill Zinc-Plated Screws support professional-grade installation efficiency by combining the benefits of a self-drill point, fine threads, and a low-profile head. The Phillips drive reduces cam-out and ensures consistent torque, while the screw's design resists pull-through and vibration loosening. These screws are well-suited for sheet metal, electrical enclosures, HVAC components, and other interior applications where precision, speed, and clean finish are critical.
