Round Bolts For Construction, Machinery & Structural Fastening

These are stainless steel or carbon steel hex socket thin pan head self-tapping screws, available in galvanized or black finish, designed for fastening soft or thin materials such as plastic parts, sheet metal, aluminum profiles, and small appliance housings. The hex socket drive ensures secure, non-slip tightening with an Allen wrench, while the self-tapping threads cut their own mating thread for fast and efficient assembly without pre-tapping. The low-profile thin head sits flush for compact, clean, and precision installations.
