Product Description Hexagonal wood screws are specialized fasteners masterfully engineered for the secure fastening of wooden components. Delve into the comprehensive exploration of their dimensions, core structure, performance characteristics, application scenarios, and usage standards to discover their unique capabilities:1, Core Structural Features1. Head DesignFeaturing an innovative exposed hexagonal column structure, these screws facilitate optimal torque transmission with standard wrenches or socket tools. The hexagonal head design enhances the contact area, ensuring superior precision in pre-tightening force control for impeccable fastening.2. Thread ConfigurationTailored with self-tapping threads specifically for wood, these screws boast a 60° tooth angle and a precisely matched tooth pitch (e.g., M6 thread with 1.0mm pitch). This design ensures exceptional compression of wood fibers, preventing splitting during insertion and securing an immaculate finish.2, Performance Parameters and Materials1. Material StandardsConstructed primarily from carbon steel grade 4.8 with optional 304 stainless steel for specific applications, these screws undergo surface treatments like galvanizing (≥ 48h salt spray test) and Dacromet processing (≥ 720h neutral salt spray) to cater to varied corrosion resistance demands.2. Mechanical PropertiesExhibiting remarkable mechanical properties, these screws offer a tensile strength of ≥ 400MPa and a yield strength of ≥ 240MPa. Compliant with JIS B 1082 standards, their single nail shear strength reaches up to 1.2kN for the M6 × 60 specification, ensuring reliable performance across applications.3, Typical Application Scenarios1. Furniture ManufacturingIdeal for reinforcing the mortise and tenon joints in solid wood furniture, these screws provide robust connections between table and chair legs and crossbeams, effectively supporting daily use vibrations and ensuring furniture durability.2. Architectural DecorationPerfect for securing keels and walls in wooden houses, these screws, used alongside moisture-proof gaskets, are resilient to temperature variations from -20 oC to 60 oC, ensuring structural integrity in diverse climatic conditions.3. Shipbuilding IndustryIn shipbuilding, these screws excel in providing durable connections between wooden decks and metal components. Crafted from 304 stainless steel, they resist seawater salt spray corrosion, making them ideal for maritime applications.4, Usage Standards and Advantages1. Operating StandardsFor optimum performance, use a screwdriver matching the screw specifications (e.g., M6 with a PZ2 head), maintaining a screwing speed of 150-200rpm and a torque of 2.5-3.0N·m to prevent thread disengagement and ensure secure fastening.2. Technical AdvantagesSeismic Performance: As per JIS B 1055 vibration tests, these screws maintain stability through 2 million cycles without loosening under 10Hz and 3mm amplitude conditions.? Detachability: Capable of enduring over three cycles of disassembly and reassembly while maintaining an impressive thread bite force of over 85%, ensuring long-term usability.Environmental Characteristics: RoHS certified, with lead content rigorously kept under 100ppm, affirming a commitment to eco-friendly standards.5, Selection and Taboos1. Selection PrinciplesChoose screws based on substrate hardness for optimal performance:? Pine/Cedar: M5 × 40 specification for a secure hold.? Oak/Walnut: Opt for M6 × 60 specification to ensure robust connections.? Plywood/MDF: Pair with nylon expansion tubing for enhanced stability and security.2. Disable SceneAvoid using these screws on thin wood boards under 15mm in thickness. Substrates such as gypsum board and hard foam board may lead to connection failure due to inadequate support and material properties.
