love these screws use them in a lot of projects now

These are cool. What else can I say? Don’t lose the bit.

I am building planter boxes and they work perfectly!

great screws. I used these to secure pieces of 2x4s when building shelves. I did have to drill pilot holes when screwing near ends of the lumber as the screws split the wood when I didnt drill pilot holes

If you work on big boy projects, sometimes you need big boy parts, and these screws are the real deal. Bought my initial pack at Lowes as I was working on my deck.I went back when I ran out, and, of course, found out they were out of stock. When I turned to the clerk behind the Pro Service Desk for help, his reply (and I kid you not) was, Cant Help Ya Buddy and sat back down. And, big box stores wonder why people shop online. So, we ordered the screws online. They are made in the USA, and if you are needing to brace some 6 x 6 or other large deck lumber, these are going to save you time and money. I also use them on the ledger boards because they screw in flush to the board, and I can put my joist hangers over the screw if necessary. I like the fact they are thin, so they dont crack the boards, but have the strength of larger screws. And, I buy USA where I can.

Love these and 20 percent cheaper than Home depot!

A great advancement over lag bolts well worth the extra cost. Used to install a bridge deck (pressure treated), the installation was a breeze using run-of-the-mill regular and impact screw drills (both corded and battery). A number of star drivers were provided with the quantity Of screws I purchased and I anticipated having to switch them out when stripping one due to carelessness. I used only one driver for 225 screws. Although I was prepared for it, the coating on the screws allowed effective install and drew the heads in flush or below the surface, thus no predrilling or countersinking was required. Out of the 225 screws, two were unusable due to extra material (not sure if metal or coating) Impeeded the driver from engaging the head. Time will tell if the screws hold up to the pressure treated lumber better than the hot dipped galvanized bolts used elsewhere on the bridge. I anticipate they will do better but I’m 66 and maybe my grandkids will find out. A contractor friend recommended these over lag bolts and I’m truly grateful for the advice.

I use this product for making quick tables, support shelves and even wood hassocks. Notice the head configuration....You can quick assemble 90 degree wood joining...just drill a small home in the edge of the lumber and the other board. Screw them together with the fastener and you discover the joint is quite strong. I suggest that they be used on real lumber and not MDF board. The screw heads are quite presentable and actually look decorative. Im always looking for better ways to join wood pieces together.

Table making .

Much nicer looking than old-school lag bolts that tend to snap. Made installing a set of exterior steps much easier. Would purchase again
