M3x6mm Phillips Pan Head Screw with Built-in Washer – Heat Sink Mounting Screw (TO-220 / TO-3P)

Description

This M3 × 6mm Phillips Pan Head Screw (HEAT SINK M3X6 MM) with a built-in serrated washer is designed for secure and vibration-resistant mounting of electronic components like TO-220 and TO-3P packages (e.g., 7805, LM317, 2SC5200, 2SA1943, IRF540). The integrated washer improves grip and distributes pressure evenly on the component tab or mica insulator.

Made of nickel-plated or stainless steel, this screw resists corrosion and ensures a firm fit in aluminum or metal heat sinks. Widely used in SMPS, amplifier boards, LED drivers, and other power circuits.
