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.
