Installation Instructions for Pogo Pins
- Pogo pins are very fragile and are not meant to be installed in a press-fit hole
- We recommend installing pins using a sandwich method wherein the pin is dropped into a two-level drilled hole (counterbored .002-.003″ larger than the diameters of the plungers and barrel)
- After pin is dropped into lower block, it should be sandwiched by another block with a matching hole
