Using these for automotive repair projects. The black washers contrast nicely with the silver nuts and hold torque well.

Exactly as described
The six-claw washers grip well and prevent loosening under vibration. Perfect for my motorcycle engine cover.

Missing a few
Quality is good but count was off by two sets in my package. Seller resolved it quickly though.

Solid Hardware
Great locking mechanism on these washers. The nuts are true 304 steel and haven't shown any signs of rust after a month in my garage.
