Product Description

Hexagonal wood screws are highly specialized fasteners meticulously crafted for securing wooden components with precision and durability. Explore their brilliance through the facets of core structure, remarkable performance, versatile application scenarios, and stringent usage standards:

1, Core Structural Features

1. Head Design

Incorporating an exposed hexagonal column structure, these screws ensure seamless torque transmission using standard wrenches or socket tools. The hexagonal head design offers a substantial contact area, enhancing the accuracy of pre-tightening force control for impeccable fastening.

2. Thread Configuration

Designed with self-tapping threads tailored specifically for wooden materials, these threads feature a typical 60° tooth angle. The tooth pitch, aligned with diameter specifications (e.g., M6 thread pitch of 1.0mm), ensures effective compression of wood fibers without causing splits during installation.

2, Performance Parameters and Materials

1. Material Standards

Crafted primarily from carbon steel grade 4.8, with the option of 304 stainless steel for specific applications. Surface treatments such as galvanizing (salt spray test ≥ 48h) and Dacromet coating (neutral salt spray ≥ 720h) cater to diverse corrosion resistance needs.

2. Mechanical Properties

Demonstrating superior mechanical strength, these screws boast a tensile strength ≥ 400MPa, yield strength ≥ 240MPa, and comply with JIS B 1082 standards. The single nail shear strength attains an impressive 1.2kN (for M6 × 60 specifications).

3, Typical Application Scenarios

1. Furniture Manufacturing

Perfect for reinforcing the mortise and tenon joints in solid wood furniture, these screws secure connections between table legs, chair legs, and crossbeams, ensuring stability and resilience against daily vibrations.

2. Architectural Decoration

Ideal for affixing keels and walls in wooden houses. When used with moisture-proof gaskets, they adeptly withstand temperature fluctuations from -20 ºC to 60 ºC, ensuring long-lasting structural integrity.

3. Shipbuilding Industry

Invaluable for connecting wooden decks to metal components; the usage of 304 stainless steel ensures exceptional resistance to seawater salt spray corrosion, safeguarding structural longevity.

4, Usage Standards and Advantages

1. Operating Standards

Utilize screwdrivers matching the specifications (e.g., M6 with PZ2 type screwdriver head), maintaining a screwing speed between 150-200rpm. Recommended torque is 2.5-3.0N · m to prevent thread disengagement and ensure secure fastening.

2. Technical Advantages

Seismic Performance: According to the JIS B 1055 vibration test, these screws maintain structural integrity over 2 million cycles without loosening under conditions of 10Hz frequency and 3mm amplitude.

• Detachability: Allows repeated assembly and disassembly for over three cycles, with the thread consistently maintaining a bite force exceeding 85%.

Environmental Characteristics: Fully RoHS certified, ensuring the lead content remains below 100ppm for eco-friendly usage.

5, Selection and Taboos

1. Selection Principles

Selection based on substrate hardness:

Pine/Cedar: Opt for M5 × 40 specifications for optimal results.

• Oak/Walnut: Recommended to use M6 × 60 specifications for maximum efficiency.

• Plywood/MDF: Best used in conjunction with nylon expansion tubing for secure fastening.

2. Disable Scene

Usage on thin wood boards (thickness < 15mm) is strictly prohibited. Additionally, avoid gypsum board, hard foam board, or other non-wood substrates to prevent connection failures.
