P2F Fixing Elements for LED PCBs BJB P2F (Push-to-Fix) Fixing Elements for LED PCBs offer low insertion loss and reliable heat dissipation due to a constant pressure. These fixing elements allow a quick assembly process that improves production efficiency and reduces production costs. The P2F fixing elements are designed for holes with a diameter of 4.3-4.8mm in PCBs. These P2F elements eliminate the potential damage from screw mounting due to low insertion force. The P2F fixing elements for LED PCBs feature shock and vibration resistance, low insertion force, and multiple coloured silicone rings that denote the various thicknesses of the rings.
