Product Description Hexagonal wood screws are meticulously crafted fasteners designed to securely join wooden components. Let's explore their distinct attributes through 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 for torque transmission using ordinary wrenches or socket tools. The hexagonal head ensures a larger contact area, significantly enhancing the precision and control of pre-tightening forces.2. Thread ConfigurationEngineered with self-tapping threads specifically tailored for wooden materials, these screws boast a 60° tooth angle. The tooth pitch is meticulously aligned with diameter specifications (e.g., M6 thread tooth pitch of 1.0mm), guaranteeing effective compression of wood fibers without causing splits when inserted.2, Performance Parameters and Materials1. Material StandardsPrimarily composed of carbon steel grade 4.8, with certain applications utilizing 304 stainless steel. Surface treatments include galvanizing (withstanding salt spray tests for ≥ 48h) and Dacromet processes (neutral salt spray tests for ≥ 720h) to cater to varying corrosion resistance needs.2. Mechanical PropertiesBoasting a tensile strength of ≥ 400MPa, a yield strength of ≥ 240MPa, and complying with JIS B 1082 standards for shear strength, these screws demonstrate a formidable single nail shear strength of up to 1.2kN for the M6 × 60 specification.3, Typical Application Scenarios1. Furniture ManufacturingIdeal for reinforcing the mortise and tenon structures of solid wood furniture, such as the connections between table and chair legs and crossbeams. These screws provide sufficient bearing capacity to withstand daily vibrational demands.2. Architectural DecorationUtilized for fastening keels and walls within wooden houses, these screws are used alongside moisture-proof gaskets and adapt seamlessly to temperature fluctuations from -20 oC to 60 oC.3. Shipbuilding IndustryPerfect for transition connections between wooden decks and metal components, the 304 stainless steel construction offers exceptional resistance to seawater salt spray corrosion.4, Usage Standards and Advantages1. Operating StandardsEmploy a screwdriver that matches the specifications (e.g., M6 corresponds to a PZ2 type screwdriver head), with a screwing speed maintained at 150-200rpm and a recommended torque value of 2.5-3.0N·m to prevent thread disengagement.2. Technical AdvantagesSeismic Performance: In compliance with the JIS B 1055 vibration test, these screws endure 2 million cycles without loosening under conditions of 10Hz and 3mm amplitude.? Detachability: Easily supports over 3 cycles of disassembly and reassembly, with the thread maintaining more than 85% of its bite force.Environmental Characteristics: Certified under RoHS standards, with lead content kept below 100ppm.5, Selection and Taboos1. Selection PrinciplesChoose based on substrate hardness:Pine/Cedar: Opt for M5 × 40 specification.? Oak/Walnut: M6 × 60 is recommended.? Plywood/MDF: Best used in conjunction with nylon expansion tubing.2. Usage RestrictionsAvoid using on thin wood boards under 15mm in thickness. Refrain from using on gypsum board, hard foam board, or other non-wood substrates to prevent connection failure.
