Product Description Hexagonal wood screws are refined fasteners meticulously crafted for securing wooden components with precision. Let's explore their features across dimensions such as core structure, performance characteristics, application scenarios, and usage standards:1, Core Structural Features1. Head DesignFeaturing an exposed hexagonal column structure, these screws allow torque transmission through standard wrenches or socket tools. The hexagonal head offers a larger contact area, optimizing the accuracy of pre-tightening force control for superior assembly.2. Thread ConfigurationDesigned with self-tapping threads optimized for wooden materials, these screws boast a tooth angle of approximately 60°. The tooth pitch is carefully aligned with the diameter specification (e.g., M6 thread tooth pitch of 1.0mm), ensuring effective compression of wood fibers without causing splits upon insertion.2, Performance Parameters and Materials1. Material StandardsConstructed from high-quality carbon steel grade 4.8, with alternative use of 304 stainless steel in certain applications. These screws undergo surface treatments like galvanizing (salt spray test ≥ 48h) and Dacromet coating (neutral salt spray ≥ 720h) to fulfill diverse corrosion resistance needs.2. Mechanical PropertiesExhibiting tensile strength of ≥ 400MPa and yield strength of ≥ 240MPa, with shear strength rigorously tested as per JIS B 1082 standards. The single nail shear strength reaches up to 1.2kN (M6 × 60 specification), ensuring durability and robustness.3, Typical Application Scenarios1. Furniture ManufacturingPerfect for reinforcing mortise and tenon joints in solid wood furniture, such as connecting table and chair legs to crossbeams. The singular nail strength accommodates daily use vibrations effortlessly.2. Architectural DecorationIdeal for securing keels and walls in wooden houses, used alongside moisture-proof gaskets. These screws withstand temperature fluctuations from -20 oC to 60 oC, ensuring stability and integrity.3. Shipbuilding IndustryEssential for transitional connections between wooden decks and metal components. The 304 stainless steel material offers formidable resistance against seawater salt spray, ensuring longevity.4, Usage Standards and Advantages1. Operating StandardsEmploy a screwdriver matching the specifications (e.g., M6 corresponding to PZ2 type screwdriver head), maintaining a screwing speed of 150-200rpm with a recommended torque value of 2.5-3.0N·m to prevent thread disengagement.2. Technical AdvantagesSeismic Performance: Undergoes JIS B 1055 vibration testing, holding steadfast through 2 million cycles without loosening under conditions of 10Hz and 3mm amplitude.? Detachability: Supports more than 3 cycles of disassembly and reassembly, with thread maintaining a bite force above 85%, ensuring continued efficiency.Environmental Characteristics: RoHS certified, with lead content maintained at <100ppm, promoting environmental safety.5, Selection and Taboos1. Selection PrinciplesSelect based on substrate hardness:Pine/Cedar: M5 × 40 specification? Oak/Walnut: M6 × 60 specification? Plywood/MDF: Optimally used with nylon expansion tubing for secure and reliable installation.2. Disable SceneAvoid using on thin wood boards with a thickness less than 15mm. Employing these screws on gypsum board, hard foam board, and other non-wood substrates may result in connection failure.
