Cross Recess Single Countersunk Fiberboard Screw 8-10x20-75 Z/Y

Product Features
Neat countersunk head for smooth installation: The tapered countersunk head with cutting ribs embeds completely into the material surface for a flush finish. The cross recess provides secure bit engagement with both power and manual tools, reducing slippage.
Coarse thread and sharp point for splitting prevention and strong holding: The specially designed coarse fiber thread delivers high penetration power, minimizing edge chipping in MDF and particleboard. The sharp point eliminates the need for pre-drilling, while the full-thread design ensures tight engagement and high pull-out resistance.
Case-hardened steel for durability and reliability: Through heat treatment, the screw achieves an optimal balance of hardness and toughness, reducing the risk of breakage or stripped recesses during power driving—ideal for high-volume assembly line work.
Yellow-zinc anti-rust coating for indoor use: The yellow-zinc passivation layer offers better rust resistance than standard white-zinc plating, effectively protecting against indoor humidity. The warm yellow-gold finish complements wood surfaces aesthetically, while keeping costs economical.
Wide specification range for diverse applications: #8 fine-thread variants suit thin sheets and light loads; #10 coarse-thread variants provide greater load capacity. Lengths from 20–75 mm cover everything from thin panels to thick joists and multi-layer boards.
