Female Low profile socket strip - 5 per Strip, 0.100" (2.54mm) spacing
3-pin headers are used with MANY accessories, and some even use "lock tab" or "buckled" connectors that physically lock them into place. Here's a socket that mates with them!
Sometimes...you just need pins. Lots of pins. Not sure how long, but lots. So here's a strip of 36 that's a convenient size to 'snik' apart to whatever length you need!
This is a very large row of high quality machine pin headers - break to fit.
