Review: Pin spacing is non-standard. One way it is .2" but the other way it is .25. They CAN be used on a .1 in. grid, but only by bending the pins. See photos. You might be able to push them into a breadboard block but the pins really are not made for that. The pins are not round. The thickness is OK but they are .04" wide. I don't know any kind of perf or pcb with a pin spacing that isn't a square grid. Otherwise the product is good. The 2.1 mm dimension mentioned in the product description is the diameter is the inner pin. ## Features - ✅Package includes: 5 PCS DC Power Jack + 1 PCS 9V Battery Clip,It is packaged in an anti-static bag for long-term storage. - ✅Fits for 2.1mm x 5.5mm plugs，Rated for a lifetime of 8000+ insertion and extraction - ✅Specialized Design: Perfect for solderless breadboards and PCB boards. - ✅This Product is widely used in Arduinos, Breadboard, PCB, DIY Project, STEM Project, etc. - ✅Why California JOS?
