Exactly as described
Needed M10 with square washers specifically. These fit the bill perfectly for our masonry anchors.

Solid construction bolts
Used these for a commercial elevator project. The galvanization looks thick and the threads are clean.

Good quality, slow shipping
The bolts themselves are Grade 4.8 as stated. Shipping took a bit longer than expected but product is good.
