Simpson Strong-Tie’s PVC Trim-Board screw, engineered for low-torque installations of PVC trim and fascia, has a triple-threaded design, a box-shaped cutter head, and a flat underhead to improve pull-through resistance and leave a clean finish. A T-20 bit is included; the screw’s six-lobe design helps reduce cam-outs for longer bit life. Look for online pricing around $11 for a 70-count box of the paintable, white, exterior-grade screws.
