Good quality, no stripped heads

High quality lag screws, nice thick paint. Came with 2 driver bits and worked very well to assemble a swingset with pressure treated lumber. Cheaper than the orange or blue store too!

Good lag screws, good price
Size: #14 x 3" Color: Bronze Number of Items: 2
I used these for installing shelf brackets onto 2x4 studs in my barn. Compared to using the old style lag bolts, these screws don't require pilot holes so they install easily. Traditional lag bolts usually require predrilling otherwise you split the wood or break the bolt or chew up the threads in the wood. I have all three of those things happen. And, when you try to remove an old lag bolt, the sap in those old 2x4's has hardened and is holding the lag bolt so tight that you round over the head of the bolt trying to remove it. These lag screws seem to fair much better in all respects. ... show more

Performed well

I use these type construction lags allot, these held up under extreme torque going into old dense wood 2x4s. Can't speak to their corrosion resistance.

Works great! I used these for an observation deck project in a wooded area. So far so good structurally. Came with 2 torx bits that are of decent quality. I would recommend.

These legs were much cheaper than my hardware store options. I use them too makeup beam out of three 2x10s. It pulled them together tightly.
