4.8×90-120mm High-Tail 410 Stainless Steel Phillips Bugle Head Coarse Thread Partial Thread Screw

Product Features
Premium 410 Stainless Steel Material: Manufactured from martensitic 410 stainless steel, it combines excellent rust and corrosion resistance with extremely high hardness and strength. Compared to ordinary carbon steel phosphated screws, it can better adapt to damp or slightly corrosive indoor and outdoor environments, possesses strong anti-aging capabilities, and significantly increases the service life of the fastener.
Dual Design of High-Tail and Bugle Head: The bottom of the screw head features a unique "high-tail" structure, which can pre-cut and clear chips when driving into the stud, significantly reducing installation torque, improving construction efficiency, and effectively preventing the board from cracking under stress. The bugle shape at the top can perfectly fit the countersunk holes of gypsum boards, sinking smoothly into the board surface without tearing the paper layer, ensuring a flat and aesthetic finished decoration surface.
M4.8 Large Diameter Coarse Thread: Possesses stronger shear and pull-out resistance than ordinary fine thread screws. The coarse thread design delivers an extremely strong grip, capable of penetrating deep into wooden or light steel studs to provide excellent fastening effects, ensuring a secure connection without loosening.
90-120mm Ultra-Long Specifications: Specially designed for heavy-duty engineering that requires penetrating multiple layers of thickened gypsum boards, high-density composite boards, or deep fixing into studs, perfectly solving the pain point of insufficient gripping power of conventional short screws in thick walls.
