Hex Head Self-Tapping Screws With Three Notches Flat Point

Our screws are newly upgraded precision protective self-tapping fasteners, specially developed to solve the pain points of substrate cracking, burr residue and labor-consuming construction of ordinary self-tapping screws on soft and precision workpieces. Breaking through the limitations of traditional single-point sharp Point and flat Point screws, this product adopts a unique symmetrical Three Notches balanced cutting structure, with three groups of precision cutting teeth evenly distributed around the Point, forming a 360° uniform stress cutting system. During self-tapping operation, the three notches structure can disperse concentrated resistance to three directions, completely avoiding unilateral stress concentration caused by single-point cutting, fundamentally solving the common problem of plastic part cracking, wood edge splitting and workpiece surface burrs in traditional tapping construction. The optimized flat point design removes the sharp piercing tip, with flat and smooth Point end, which will not produce instantaneous impact force on the inner wall and bottom of thin-wall closed workpieces, effectively protecting the structural integrity of precision electronic parts and thin decorative components. The standard regular hex head structure has high tool compatibility, matching all common hexagonal manual and electric tools, with stable stress transmission and no tool slipping, greatly improving the efficiency of batch assembly and later disassembly and maintenance. The thread part adopts precision rolling process, with uniform tooth pitch and smooth tooth surface. Cooperating with Three Notches synchronous cutting, it can form complete and standard internal threads in one step, with tight meshing, uniform stress and strong pull-out resistance. Made of high-quality high-strength steel, the screw has moderate hardness and toughness, ensuring smooth cutting without tooth breakage or deformation. With exclusive balanced labor-saving cutting, full-range workpiece protection and high-precision tapping effect, this product is a professional protective fastening solution for modern precision manufacturing and refined decoration projects.
