This eliminates the need for a separate tapping operation, significantly speeding up assembly and reducing costs.To Provide a Large Bearing Surface: The integrated washer (the head) spreads the clamping force over a wider area than a standard screw head. This prevents the screw head from pulling through or deforming soft materials (like plastic or thin sheet metal) and ensures a tighter, more secure fit.Key Advantages:Faster Assembly: No pre-tapped hole needed.Cost-Effective: Reduces labor and machining steps.Vibration Resistance: Maintains a tight joint under stress.Excellent for Thin Materials: The washer head prevents pull-through. To Generate High Clamping Force: The screw pulls two or more pieces of material together tightly, creating a secure, vibration-resistant joint.To Seal and Protect: In many cases, the wide bearing surface of the washer head can help seal the hole against moisture and dirt, especially when used with a sealing washer (made of rubber or neoprene) attached to the base.Structure:The structure of a washer head self-tapping screw can be broken down into four main parts:A. The Head (Washer Head):This is the most distinctive feature. Instead of a small, separate washer, the head is a single, wide, flat disc (the "washer") with a drive recess in the center.Drive Type: The recess is commonly a Phillips (PH), Pozidriv (PZ), or Hex (Allen) drive.Function: The large diameter of the washer head provides the extensive bearing surface crucial for distributing pressure.B. The Shank:The unthreaded section of the screw just below the head.Its diameter is typically equal to or slightly smaller than the major diameter (the outer diameter) of the threads.Function: It allows the screw to pass freely through the first material (e.g., a metal bracket) before the threads engage with the second, base material.C. The Threads:These are sharp, aggressive, and spaced relatively far apart (a coarse pitch) compared to machine screw threads.They are designed to aggressively cut into the base material, displacing chips rather than removing them (in the case of thread-forming screws for plastics) or actually cutting and removing material (in the case of thread-cutting screws for metal).Function: To create the mating threads that provide the holding power.D. The Point (Self-Tapping Tip):This is the engineered end of the screw that starts the hole and begins the tapping process. There are several common types:Gimlet Point: A sharp, tapered point with a cutting flute. Common for wood and some plastics.Type A, B, AB (for metal): These have a blunt start with cutting flutes that act like a tap to cut threads in metal.Drill Point (Tek Point?): This is a highly efficient tip that incorporates a fluted drill bit at the end. It can drill its own pilot hole through metal, cut threads, and fasten in a single operation, eliminating the need to drill a pilot hole beforehand. This is extremely common in HVAC, metal framing, and automotive applications.
