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.
