Professional Grade

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.

Good but tight

Threads were slightly tight initially but loosened up after a few uses. Quality seems durable for the price point.
