Hinge Head Torx Three Notches Concrete Self-Tapping Fasteners

Our screws are crafted with high-hardness stainless steel, integrating Hinge Head, Torx Recess and exclusive Three Notches Thread Structure, specially designed for hard concrete, cement wall and stone base material fastening projects. Different from ordinary wood self-tapping screws, this product adopts innovative three notches cutting thread design, which can effectively break dense and hard cement and concrete structures, solve the problem of difficult tapping and low efficiency of traditional screws on hard walls, and realize fast and labor-saving self-tapping fixing. The upgraded Hinge head structure fits flush with the wall surface after installation, without protruding parts, ensuring smooth and neat wall finish, perfectly suitable for exposed wall decoration and mounting scenarios. The precision torx anti-slip recess matches professional tools perfectly, realizing stable high torque transmission, avoiding tool slipping and screw head damage during hard wall drilling, and improving construction stability. Made of high-strength stainless steel, the whole screw body has excellent hardness and toughness, not easy to bend, break or wear during hard substrate operation. The deep self-tapping threads can bite into concrete walls firmly, with strong pull-out resistance and anti-loose performance, maintaining long-term stable fixing effect. These professional concrete fasteners are essential hardware for building wall decoration and hard base material installation projects.

Key Features

- Three Notches Thread Structure: Exclusive three notches thread design, strong cutting and breaking ability for hard concrete and cement layers, reduces tapping resistance, realizes labor-saving and efficient hard wall fixing.

- Hinge Head Design: Optimized Hinge head structure, fits flush with the wall surface after locking, no protrusion, smooth and beautiful installation effect, perfectly suitable for exposed wall decoration and surface mounting scenes with high flatness requirements.

- Torx Anti-Slip Recess: Precision torx drive groove design with large force-bearing area, effectively avoids tool slipping and screw head abrasion during high-torque hard wall drilling, ensuring stable and efficient construction operation.

- Three Notches Thread Teeth: Professional three notches cutting structure with strong breaking and cutting performance, effectively splits hard concrete and cement layers, reduces construction resistance, and solves the difficulty of traditional screws unable to drill hard walls.

- High-Hardness Stainless Steel Material: Adopts customized high-strength and high-hardness stainless steel raw material, with excellent compression resistance, bending resistance and wear resistance, no fracture or deformation during hard substrate drilling, stable and durable performance.

- Deep Anti-Loose Threads: Uniform and deep self-tapping threads with strong wall-biting force and pull-out resistance, effectively resist vibration and load pressure, not easy to loosen after long-term wall fixing.
