What This PCB-Mount Power Tap Does
The 1-55323-0: Each of the 10 positions accepts a 6-32 machine screw, making this a fixed distribution point on the board — you land ring-tongue or spade terminals from power wires directly onto the screw posts, then solder the pins to the PCB.
Through-hole solder termination — the 10 pins insert into plated holes and are wave-soldered on the opposite side. The 6-32 screw tap is the wire-side interface: use a 6-32 UNC screw (not included) to clamp a ring or fork terminal against the pad. The screw size is standard hardware, easy to source. The Bulk package means these ship loose in a bag or tube, not on a reel.
