Hex head roofing fasteners with EPDM bonded sealing washers, in Ruspert or zinc coating — engineered to keep metal and timber roofs watertight for years. 六角頭屋頂螺絲，搭配 EPDM 防水華司，提供 Ruspert 或鍍鋅表面處理，長期守護金屬與木結構屋面。
Our roofing screws combine a self-drilling or Type-17 point with a hex washer head and pre-assembled EPDM washer that seals the drilled hole against water and weather. Ruspert coating provides high salt-spray corrosion resistance for coastal and industrial environments; standard zinc plating suits lighter-duty applications.
屋頂螺絲結合鑽尾（或 Type-17 尖尾）與六角華司頭，預組 EPDM 橡膠華司，有效密封鎖固孔、防止滲水。Ruspert 表面處理具高耐鹽霧腐蝕性，適合沿海及工業環境；一般用途則可選擇鍍鋅處理。
