Product Description

Hexagonal wood screws, the ultimate solution for fastening wooden components with precision and reliability, are revolutionizing the industry. With an innovative design focused on core structure, performance, application versatility, and adherence to usage standards, these screws stand out as the epitome of excellence.

1, Core structural features

1. Head design

Featuring an exposed hexagonal column structure, these screws ensure optimal torque transmission using ordinary wrenches or socket tools. The hexagonal head offers an expanded contact area, significantly enhancing the precision of pre-tightening force control, setting new standards in fastening technology.

2. Thread configuration

Designed with self-tapping threads tailored for wooden materials, these screws boast a 60 ° tooth angle and a pitch precisely matched to diameter specifications (e.g., M6 thread pitch of 1.0mm). This ensures wood fibers are effectively compressed without splitting, guaranteeing a flawless finish and unmatched durability.

2, Performance parameters and materials

1. Material standards

Constructed primarily from carbon steel grade 4.8 and occasionally 304 stainless steel, these screws undergo surface treatments like galvanizing (salt spray test ≥ 48h) and Dacromet (neutral salt spray ≥ 720h) to surpass diverse corrosion resistance needs, ensuring longevity and reliability.

2. Mechanical properties

With a tensile strength of ≥ 400MPa, yield strength of ≥ 240MPa, and shear strength rigorously tested per JIS B 1082 standards, each M6 × 60 screw demonstrates exceptional single nail shear strength of up to 1.2kN, manifesting robust performance in all applications.

3, Typical application scenarios

1. Furniture manufacturing

Perfect for enhancing the mortise and tenon structures in solid wood furniture, these screws ensure robust connections between table and chair legs and crossbeams, providing reliable support and meeting vibration requirements for everyday use.

2. Architectural decoration

These screws are ideal for fixing keels and walls in wooden houses. When used with moisture-proof gaskets, they easily adapt to temperatures ranging from -20 ºC to 60 ºC, ensuring steadfast performance in any climate.

3. Shipbuilding industry

In shipbuilding, these screws facilitate the transition connection between wooden decks and metal components. The 304 stainless steel material resists seawater salt spray corrosion, promising durability and reliability in marine environments.

4, Usage standards and advantages

1. Operating standards

Employ a screwdriver matching the specifications (e.g., M6 requires a PZ2 type head), maintaining a screwing speed of 150-200rpm and a recommended torque value of 2.5-3.0N · m to prevent thread disengagement and ensure secure fastening.

2. Technical advantages

These screws exhibit superior seismic performance, withstanding 2 million vibration test cycles under JIS B 1055 standards without loosening, even at 10Hz and 3mm amplitude.

• Detachability: Offering support for more than 3 disassembly and reassembly cycles, the threads maintain a bite force of over 85%, ensuring resilience and versatility in reuse.

Environmental characteristics: Proudly RoHS certified, these screws contain less than 100ppm of lead, underscoring their commitment to environmental safety.

5, Selection and taboos

1. Selection principles

Choose based on substrate hardness:

Pine/Cedar: Opt for the M5 × 40 specification for a secure and perfect fit,

• Oak/Walnut: The M6 × 60 specification is ideal for these hardwoods, ensuring robust fastening,

• Plywood/MDF: Pair with nylon expansion tubing for optimal performance and security.

2. Disable Scene

Avoid using on thin wood boards less than 15mm thick and non-wood substrates such as gypsum board or hard foam board, which may lead to connection failures.
