Single position machine pin sockets. These pressfit sockets are mounted by inserting into a PCB hole and applying some force. They stay firmly in place with tension and can then be easily soldered to the circuit board. These sockets can fit any pin spacing, such as the non-standard 0.15” spacing of the vintage-style stripboard (vs. 0.10” on standard stripboard). They can also jump rows so that they are not all in a line. The press-fit machine pin sockets are also very low profile and have a very minimal impact on the resulting look of the build. For pins sizes .015 -.025". The recommended mounting hole diameter is 0.057".
