Good if you are Careful
Good price for long lag screws. If you are not careful in drilling the right sized pilot hole and lubricating the bolt (I use bar soap), the lag screws may break when tightening them.

They Break easily.
Had to buy a longer drill bit to use. I would drill in about 8 inches expecting the screw to seat in the last 4 inches. I was unable to achieve that and had to drill the entire length to keep the bolts from snapping.

First three sheared off
The first three I used sheared off when screwing into hardwood (beech). So I'd say that's not acceptable metal. Worked OK if I predrilled the wood.

Great product
Just what I needed for my project. Highly recommended.

Cheap, fragile
These are really long lag screws, however if you try to drive them into anything (I was driving them into live Juniper which is very soft wood) they will shear off. You have to pre-drill the entire length of the hole or you'll end up with the head of the screw in your bit driver... If you have a nice long bit and want to take the time to pre-drill they are probably OK but you'll still want to use 2 b/c I wouldn't trust them to hold. If you don't want to pre-drill, get a decent screw from somewhere else. These are pretty bad.
