Grabber's #8 x 2-1/2 in. LOX 3 Drive Flat-Head Coarse-Thread Sharp-Point Yellow-Zinc Collated Screws incorporate a 23° Grabber point and underhead design that helps the flat head seat cleanly into wood. The LOX recess is engineered for high-torque applications with reduced stripping, while the coarse thread promotes fast engagement in common wood substrates. Designed for use with depth-sensitive screw guns, these fasteners are well suited for professional subfloor installation where repeatable fastening and efficient workflow are important
