These screws are multi-purpose universal self-tapping fasteners optimized for daily conventional assembly and soft substrate fastening. Adopting an integrated truss head with enlarged washer flange structure, it breaks the stress limitation of ordinary small round head screws. The ultra-large flat pressure-bearing surface can uniformly disperse locking extrusion force, effectively preventing soft wood, plastic and thin composite plates from local sinking, crushing and loosening during fastening, greatly improving assembly stability. Equipped with a classic universal Phillips recessed drive, it has no tool matching threshold, convenient for manual and electric rapid construction. The streamlined high-Tapping Point realizes fast self-positioning and piercing tapping, supporting one-step efficient fixing without pre-drilling. Featuring outstanding anti-sinking performance, ultra-wide universal adaptability and simple and efficient construction, these screws are the most widely used standard fasteners for furniture assembly, daily hardware connection and decorative conventional fastening projects.

These screws are high-precision anti-slip reusable fastening fasteners, upgraded on the basis of ordinary cross screws with exclusive Pozi Pozi drive structure. Different from traditional ordinary cross grooves with easy slipping and low torque resistance, the upgraded Pozi groove has a more three-dimensional fitting structure, larger contact area with tools and stronger friction locking force, which can bear higher tightening torque without groove slipping and rounding, supporting repeated disassembly and maintenance. The finely polished round pan head has smooth and burr-free surface, with delicate and uniform appearance, perfectly adapting to exposed installation and high-aesthetic assembly scenarios. The streamlined high-Tapping Point realizes fast and neat piercing tapping for wood, plastic and composite materials, with accurate positioning and no substrate burrs. Featuring high-torque anti-slip performance, reusable structural stability and high aesthetic appearance, these screws are widely used in precision furniture fine assembly, electrical equipment shell fixing and small precision parts connection projects.

These screws are aesthetic anti-corrosion integrated drilling fasteners, specially designed for black tone matching decoration and indoor anti-rust fastening scenarios. Different from ordinary silver galvanized drill Point screws with single appearance and poor decoration, this product adopts high-temperature black paint process on the head surface, featuring uniform matte texture, strong wear resistance and no fading, perfectly matching black hardware and dark-style decorative structures. The classic cross recessed drive structure has universal tool adaptability, convenient for daily assembly and batch construction. Equipped with precision high-efficiency drill Point, it supports one-step drilling, tapping and locking for various thin metal plates and decorative profiles. The flat countersunk head achieves flush concealed installation with neat and integrated surface. Combining unique decorative appearance, excellent anti-rust performance and efficient drilling capacity, these screws are exclusive fastening solutions for modern black-style refined decoration, indoor metal plate assembly and matching hardware installation projects.

These screws are heavy-duty flush-mount self-tapping fasteners customized for thick substrate large-stroke fastening and flat concealed assembly. Adopting a unique coarse pitch thick thread design different from conventional fine-thread screws, it features larger tooth depth and wider thread spacing, forming a stronger three-dimensional wrapping bite force on thick wood, plywood and composite boards, effectively solving the problem of insufficient holding power of fine-thread fasteners on thick substrates. The flat blunt point structure avoids sharp piercing damage, protecting the integrity of thick workpieces and preventing bottom cracking and penetration deformation. Equipped with a flat countersunk head and precision torx anti-slip drive, it realizes fully flush concealed installation and high-torque stable locking. With the core advantages of fast locking speed, super strong holding power and flat aesthetic assembly, these screws are widely used in thick wood furniture structure fixing, large decorative board concealed assembly and heavy-load wood engineering fastening projects.

These screws are multi-structural composite reinforced high-strength drilling fasteners, integrating four core exclusive structures: flat square hole concealed head, under-head anti-displacement reinforcing ribs, high-bite Three Notches threads and high-penetration Wing drill Point. The under-head reinforcing ribs enhance head rigidity to avoid deformation and displacement during heavy-load locking; the Three Notches threads provide three-dimensional occlusive anti-loose bite force; the Wing drill Point realizes stable high-efficiency drilling for hard thick materials; the flat square head achieves flush concealed flat installation. Breaking the single structural limitation of ordinary drill Point screws, this product has ultra-high structural strength, anti-displacement stability and hard material adaptability, uniquely suitable for high-precision flat concealed assembly, heavy-load anti-displacement fixing and hard material industrial drilling engineering projects.

These screws are precision anti-crack labor-saving tapping fasteners, innovatively combining symmetrical Three Notches cutting teeth and protective flat Point structure. Different from traditional sharp Point self-tapping screws that are easy to crack substrates, the three notches balanced cutting design disperses tapping pressure evenly, greatly reducing construction resistance and avoiding cracking and burrs of plastic, soft wood and thin-wall parts. The flat point structure eliminates sharp impact force, fully protecting the bottom structure of precision workpieces. Matched with standard universal hex head, it supports efficient batch assembly and repeated maintenance. Featuring unique balanced labor-saving cutting performance, superior anti-crack protection and burr-free precision tapping effect, these screws are ideal for electronic precision parts, plastic components and soft wood decoration assembly projects.
