Stainless Steel Flat Head Torx Half Thread Cut Tail Screws With Under-Head Ribs & Twisted Tail

Our screws are high-end customized precision fasteners crafted with high-quality stainless steel, integrating five core advantages of flat flush head, anti-slip torx groove, under-head anti-loose ribs, scientific half thread and high-grip twisted point, specially developed for heavy-duty, high-vibration and thick-plate precision assembly scenarios. Aiming at the defects of insufficient gripping force, easy substrate deformation and poor vibration resistance of ordinary full-thread cut point screws, this product adopts targeted structural optimization. The innovative twisted point structure forms a spiral cutting and grabbing track during tapping, which can deeply bite into thick wood plates, density plates and composite thick materials, greatly improving the pulling resistance and connection firmness. The scientific half thread design retains a smooth rod body in the middle section, which avoids excessive thread extrusion on thick workpieces, effectively preventing substrate bulging, cracking and deformation, and protecting the structural integrity of thick plates. The under-head raised ribs increase the friction coefficient between the screw head and the mounting surface, locking the fitting position tightly to prevent screw back-off and loosening caused by long-term equipment vibration. The ultra-flat flat head realizes flush installation without protrusion, and the precision torx recess ensures stable and non-slip high-torque assembly. Supported by high-quality stainless steel material, the whole screw has strong toughness, hardness and anti-rust performance, maintaining stable high-grip anti-loose performance in long-term heavy-duty and vibration working environments, becoming reliable professional fasteners for high-standard thick plate assembly projects.

Key Features
