Hexagonal wood screws, an essential in the toolkit for woodworking, offer unparalleled strength and reliability. Their design is meticulously crafted, focusing on core structure, performance excellence, diverse application scenarios, and strict adherence to usage standards:
1, Core Structural Features
1. Head Design
Featuring an innovative hexagonal column structure, these screws ensure seamless torque transmission with standard wrenches or socket tools. The hexagonal head expands contact area, enhancing precision in pre-tightening force control for superior fastening.
2. Thread Configuration
Fitted with self-tapping threads tailored specifically for wood, the threads feature a 60° tooth angle, precisely matched to diameter specifications (e.g., M6 tread with 1.0mm pitch). This design ensures effective compression of wood fibers without causing splits during insertion.
2, Performance Parameters and Materials
1. Material Standards
Crafted from robust carbon steel grade 4.8 and in some cases, 304 stainless steel, these screws undergo surface treatment like galvanizing (salt spray test ≥ 48h) and the Dacromet process (neutral salt spray ≥ 720h) for superior corrosion resistance.
2. Mechanical Properties
With a tensile strength of ≥ 400MPa and yield strength of ≥ 240MPa, these screws are rigorously tested according to JIS B 1082 standards, boasting a single nail shear strength of up to 1.2kN (M6 × 60 specification), ensuring exceptional durability.
3, Typical Application Scenarios
1. Furniture Manufacturing
Ideal for reinforcing the mortise and tenon structures in solid wood furniture, these screws secure table and chair legs to crossbeams, with a load capacity that meets everyday vibration requirements.
2. Architectural Decoration
Perfect for securing keels and walls in wooden houses, these screws work in tandem with moisture-proof gaskets to withstand temperature fluctuations from -20 ºC to 60 ºC.
3. Shipbuilding Industry
Essential for connecting wooden decks to metal components, the 304 stainless steel variant excels in resisting seawater salt spray, ensuring longevity even in harsh marine environments.
4, Usage Standards and Advantages
1. Operating Standards
Use a specification-matching screwdriver (e.g., PZ2 for M6), with controlled screwing speeds of 150-200rpm and a torque recommendation of 2.5-3.0N · m to prevent thread disengagement.
2. Technical Advantages
Seismic Performance: As per JIS B 1055 vibration testing, these screws sustain 2 million cycles without loosening under 10Hz and 3mm amplitude.
• Detachability: Allows over 3 cycles of disassembly and reassembly, maintaining thread bite force above 85%.
Environmental characteristics: Compliant with RoHS, ensuring lead content is <100ppm for eco-friendly use.
5, Selection and Taboos
1. Selection Principles
Choose according to substrate hardness:
Pine/Cedar: M5 × 40 specification
• Oak/Walnut: M6 × 60 specification
• Plywood/MDF: To be used in conjunction with nylon expansion tubing for optimal performance.
2. Disable Scene
Avoid using with thin wood (thickness < 15mm). Non-wood substrates like gypsum or hard foam boards can lead to connection failures.
