HP bolts, often self-drilling screws with a hexagonal head, are designed for efficient and secure fastening without pre-drilling. They come in various materials like mild steel and stainless steel, with different finishes like zinc plating or hot-dip galvanization. Their sizes range from M4 (4mm) and larger, with lengths extending to several inches. These bolts are commonly used in construction, industrial applications, and for DIY projects, offering strong holding power.
