Screw terminal blocks are the clean, maintainable solution for PCB-to-wire connections — no solder, no loose ends, easy to swap out later. These 3.5mm pitch 2-pin blocks are a practical size: wide enough for a range of wire gauges, compact enough not to dominate your board, and designed to snap together to build up any terminal count you need.

Key Features

  • Pitch – 3.5mm
  • Pins – 2-pin per block
  • Snap-Together – Link multiple 2-pin and 3-pin blocks side-by-side for custom lengths
  • Screw Adjustment – Standard flathead screwdriver, easy to tighten and release
  • PCB Mountable – Fits most perf/proto-board (mount diagonally for 2.54mm grid boards)
  • Pack of 5 – 5× 2-pin blocks per order
Note: These are 3.5mm pitch — they do not fit 2.5mm spaced PCB holes and do not fit into solderless breadboards.

Ideal For

  • PCB-to-wire connections on custom and proto boards
  • Power input terminals, sensor connections, and signal wiring
  • Any project where re-wiring or maintenance is anticipated
