  • Good project hardware.
Size: #14 x 5" Color: Black Number of Items: 4
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.

  • 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
