content: Does anyone sell single-pin sockets like this? I generally take a typical DIL socket and remove the pins from the plastic, but it is time consuming. I use these on PCBs where I want a pin socket that is flush with the surface of the PCB. I make the plated hole on the PCB a little bigger than normal, insert this pin into the plated hole, and then solder. I then cut the stem off, so I actually don't need the stem. I've been doing this for years, and really never bothered to think maybe someone already sells these.

content: In the US, Samtek and Mill-Max come to mind for screw machine type sockets.Mind you, what you’re doing is probably the cheapest way to get ‘em.

content: Quote from: groinksan on December 13, 2020, 02:46:21 amIIRC Augat used to sell IC sockets which used these type of pins fitted onto a DIP-shaped metal carrier. After soldering the pins into the PCB the metal carrier was removed leaving the free-standing pins. This gave better air circulation around the DIP package and reduced inter-pin capacitances.

content: Not quite what you may be looking for, but I have used these single pin sockets from TE Connectivity as sockets for Nixie tubes.With the right size PTH hole they press in nicely and are sealed on the solder side of the socket.Available from Mouser and maybe others:https://nz.mouser.com/ProductDetail/571-5645500-1Datasheet:https://www.te.com/commerce/DocumentDelivery/DDEController?Action=srchrtrv&DocNm=5645500&DocType=Customer+Drawing&DocLang=English&PartCntxt=5645500-1&DocFormat=pdfI have not checked if they do a smaller diameter. (The Nixie tubes I was using had quite large pins.)Warning: Very, very expensive, however they were perfect for my Nixie clock at the time.

content: Not exactly sure what material is used, but you could try doing your method but with solvents. Put a few sockets and some solvent in an appropriate vessel overnight and you have a set of pins.If it's just cheap plastic, maybe something like acetone would work, but my assumption is that it's something a bit more resistant than ABS, so you may need to look at more specialty solvents and appropriate vessels/safety/disposal - it could be quite a task if it requires exotic chemicals or handling - but if it's manageable, it's very low effort.

content: If you are near Eastern Cleveland (Mentor), our surplus store has them for about $0.30 each pin (https://www.electronicsurplus.com/search/machined+pin+in+carrier). I got a bunch of them when the store was in Slavic Village (near downtown) and cheaper.

content: I know someone makes them, but it was so long ago (80's) I don't remember who.They came on a metal frame - sort of a chip substitute to hold the pins. You'd solder them in, then just pull off the frame with a pair of needle-nose.

content: Quote from: groinksan on December 13, 2020, 02:46:21 amThat is what I do also. Individual collet socket pins are much more expensive, but are available and in all different sizes. Plan on buying 100s or 1000s at a time to get even sort of reasonable prices.They also work well for holding discrete parts which might be changed.QuoteI do the same thing and if the collet socket pin does not sit flush, then I use a number drill to ream the plated hole. I use pin vices to hold the number drills.I was going to include a photograph but the forum returned, "Your attachment has failed security checks and cannot be uploaded.
