High-volume subfloor and underlayment screws. Twinfast coarse thread, yellow zinc coating, wood-to-wood.
CS Yellow Zinc subfloor screws use a twinfast coarse thread that pulls boards tight in a single pass without pre-drilling or cam-out. Yellow zinc coating handles interior moisture. Collated coil format for the FDVL43 keeps crews moving across the deck with fewer reloads between sheets.
