Besides that type of use, is there any difference between spline and 12pt in functionality? Spline seems to have more options because it can do square if I'm not mistaken.Use them all the time...We have spline, 6 and 12 point hardware on the jets and it's handy not to have to change sockets every time there's different heads on the hardware. If I know everything is 12 point or 6 point, and not goobered with sealant, I'll grab 12 point sockets. If there's sealant or there might be splines, then the spline sockets. I almost never grab a 6 point socket out of the tool boxes.
Not sure on using them on square or 8 point hardware. 6 and 12 point use 30 and 60 degree angles between faces, while square and 8 point use 90 and 45 degree angles. Square *might* work with 90 being a multiple of 30, but I've never tired it before. Haven't had anything with square hardware to mess with in years....not even an Erector set!Spline seems to have more options because it can do square if I'm not mistaken.
yeah i still use em, not my first grab but theyre handy when you need more contact and dont feel like rounding off some crusty fastener with 12 point junkI was looking at a MP ad with Craftsman sockets.
