To help a socket stay on a bolt head modify a 6 point socket by grinding it shorter which which will remove the chamfer and increase the grip.

[right way right]

I have done that camphor grinding many times for shallow bolt heads and yes it works.
If be heads are really rusted down, a 1/2 socket may fit better than a 13mm.
Cheap tools also make jobs hard, sometimes even impossible.Ihave ne er split a Snap On socket but have split mang Craftsman sockets. They are junk. (The get the grinder mods)

Yes, in fact I have a proper size (17mm) deep (impact)socket and grinding off the chamfer won’t hurt anything. Was thinking of that, this morning... But a 6 point wrench might be better???
