I found this one and only nail in the back of my really old workbench and am wondering what it was used for. It looks like it was dipped in galvanized material and has a domed head.

My l[color=#111111]inear motion ball bearing slide block did not come with this little knob. I don't know what it's called. I need to purchase a replacement for mine but I don't know the name. This side hole here is used to be grease in there, I think.[/color] [img]https://cimg1.ibsrv.net/gimg/www.doityourselft.com-vbulletin/844x610/linear_motion_block_b9471816e9bc5139e0fdee4522ad93445d978a17.png[/img]
