Gets Job Done. Good Price.
Size: 36mm
I used this to take the large bolt off the triple tree clamp on my motorcycle. For this purpose it worked great. I doubt I'll need to do this often and I'm unlikely to ever own the vehicles who's oil filter it fits but glad I bought it. If you need a 36mm bolt undone and have a 3/8th drive wratchet this is an economical way to get it done.

High quality
Size: 36mm
Perfect fit for my 2008 Audi TT oil filter cap. FYI, don't bother removing the plug in the cap if it is stripped. Mine was stripped by Audi mechanics and I thought it held the cap in place. It does not. I tried to loosen it with a chisel and broke the cap. An expensive, rookie mistake.
