Technic pin question

[JohnsLegos]

Hi all! I am rebuilding something I made quite some time ago with newer Lego parts and some old ones as well. I recently was on Bricklink looking for a part I needed and only a few sellers had it and some of the prices were waaaaayyyyy too much. After looking on the site in a different area I noticed the pin I wanted (part #4459) was an older part BUT there was a similar part (part # 2780) which looked like a newer pin design. Now I know these pins had a better grabbing power so things would not move (which is what I want) so does the newer pin have a better "holding power" then the older ones?? I am looking to order some soon so your comments mean alot. Thanks!!

The old high friction pins aren´t being produced anymore. I don´t know of any third party product as well. That´s sad, for exactly the reasons you are describing. They have one big disadvantage - smaller kids are not able to pull them out easily. Luckily you can look up in BL which sets include them and I suggest you just buy one of them, used and better incomplete - that could be your perfect bargain.

MouldKing (also Sembo, or anyone who uses GoBricks pieces) pins are pretty stubborn, on a par with the old Lego pins, I'd say.
 

However... is this perhaps demonstrating a misconception? No matter how strong the pins are, something which is held only by friction is always at risk of pulling out.

With modern studless Technic, you should instead look to form-lock anything which is at risk of pulling out. This means putting pieces at right-angles so that the only way the assembly could pull out, is if the locking piece gets split in half.

Those 2780s are good pins. I sorted out all my older pins so now I only use 2780 pins

Old sets may have replaced parts and not have the pins you want. Be sure to ask before buying.
