Product Description

Hexagonal wood screws are precision-engineered fasteners crafted specifically for the robust and reliable adhesion of wooden components. Delve into their excellence through an exploration of core structural dimensions, outstanding performance features, versatile application scenarios, and essential usage standards, defining their superiority in the market:

1, Core Structural Features

1. Head Design

Featuring an exposed hexagonal column structure, these screws enable efficient torque transmission using standard wrenches or socket tools. Their hexagonal head maximizes contact area, significantly enhancing the precision of pre-tightening force control, ensuring a secure and stable fit.

2. Thread Configuration

Engineered with self-tapping threads tailored for wooden materials, these screws feature a typical 60° tooth angle. The pitch is meticulously matched to diameter specifications, such as M6 with a 1.0mm pitch, ensuring excellent fiber compression without splitting during installation.

2, Performance Parameters and Materials

1. Material Standards

Crafted primarily from carbon steel grade 4.8, with select use of 304 stainless steel, these screws boast superior durability. Surface treatments like galvanizing (surpassing 48h in salt spray tests) and Dacromet process (withstanding ≥ 720h in neutral salt spray) cater to diverse corrosion resistance needs.

2. Mechanical Properties

These screws exhibit impressive mechanical strength with tensile strength ≥ 400MPa, yield strength ≥ 240MPa, and shear strength verified by JIS B 1082 standards, achieving single nail shear strength of up to 1.2kN (M6 × 60 specification).

3, Typical Application Scenarios

1. Furniture Manufacturing

Ideal for reinforcing solid wood furniture mortise and tenon structures, these screws ensure robust connections between table and chair legs and crossbeams, providing ample bearing capacity to withstand daily vibrations.

2. Architectural Decoration

Perfect for securing keels and walls in wooden houses, when used with moisture-proof gaskets, they adeptly handle temperature fluctuations from -20 ºC to 60 ºC, ensuring unwavering stability.

3. Shipbuilding Industry

These screws serve as indispensable allies in the transition connection between wooden decks and metal components of ships, with their 304 stainless steel composition offering high resistance to seawater salt spray corrosion.

4, Usage Standards and Advantages

1. Operating Standards

For optimal performance, use a screwdriver matching the screw specifications (e.g., M6 with PZ2 type head), maintain a screwing speed of 150-200rpm, and adhere to a recommended torque of 2.5-3.0N·m to prevent thread disengagement.

2. Technical Advantages

Seismic Performance: Withstand up to 2 million cycles without loosening during JIS B 1055 vibration tests, enduring 10Hz at a 3mm amplitude.

• Detachability: Enjoy seamless disassembly and reassembly over 3 times, while retaining over 85% of thread bite force.

Environmental Characteristics: Compliant with RoHS standards, ensuring lead content remains below 100ppm, reflecting a commitment to sustainability.

5, Selection and Taboos

1. Selection Principles

Choose according to substrate hardness:

Pine/Cedar: Opt for M5 × 40 specifications.

• Oak/Walnut: Utilize M6 × 60 specifications for optimal adhesion.

• Plywood/MDF: Enhance with nylon expansion tubing for superior results.

2. Disable Scene

Avoid using on thin wood boards with thicknesses under 15mm. Refrain from applications on non-wood substrates like gypsum board and hard foam, as they may compromise connection integrity.
