Purchased these to use for brake washers around banjo bolts. They fit ok and seal, but they don’t provide the contact surface I’d prefer.

Huge variety for the price. Quality seems to be acceptable. Great to have just in case. I’m a fan of OEM drain washers but these still seems to function.

Sorry no Photos, but this product has 11, eleven different sizes of Oil Drain Plug Crush Washers, and these things are made of copper, nice find. I'm using them for my Tundra 2007, Oil change, that I'm going to be doing myself, once I round up all the needed tools and supplies. Yeah, great Find !

I do our oil changes for a few vehicles and this had every size I've needed and there have been zero oil drain bolt leaks with proper (light) torquing. They do what they should, are cheap, and it's a good set of sizes if you're changing oil in multiple vehicles.
