Product Applications
Furniture Manufacturing: Assembly of cabinets, tables, chairs, and other panel furniture, suitable for various engineered wood and solid wood substrates.
Outdoor Construction: Installation of wooden structures, fences, doors, and windows, with resistance to corrosion from moisture and salt spray environments.
Light Industrial Assembly: Fastening of appliance housings and plastic parts, compatible with automated production lines and visible component installation.
DIY Repair: Home renovation, handicraft projects, and component repairs, offering stable fastening and easy operation.
Product Features
Square Drive for Slip‑Resistant Driving: The square recess delivers direct torque transmission, minimizing bit cam‑out; compatible with both manual and power tools, suitable for DIY as well as mass production.
Sharp Point for Efficient Self‑Tapping: The sharp point with coarse threads enables rapid driving into substrates without pre‑drilling in many cases, with low insertion resistance, good anti‑loosening performance, and reduced risk of damaging workpieces.
Pan Head for Even Load Distribution: The round pan head offers a large contact area and uniform pressure distribution, reducing the likelihood of crushing the workpiece, and leaving a flush, neat appearance after installation.
CL4‑Grade Long‑Lasting Corrosion Protection: The composite coating resists salt spray and moisture, making it suitable for indoor and outdoor moderately corrosive environments, with an extended service life.
Versatile Sizing for Broad Compatibility: Available in 8#–10# diameters and 12–25 mm lengths to flexibly accommodate different substrate thicknesses and assembly requirements.
