FastenMaster FMHLGM412-50 HeadLOK Heavy-Duty Flathead Fastener, 4-1/2 Inches, 50-Count

Drives like a champ. Way easier and faster than the 3/8 bolt it replaces. Hoping the engineers did their homework because these fasteners are too good to believe.

The best screws. Great quality. V easy to use

Excellent, heavy duty.

These are great lags/screws. I bought another box after using this whole box. They do not strip and hold up very heavy items in my home gym and garage. I definitely recommend these.

These are great screws. The other reviewers have covered their good points. There is a catch--the driver needed to use them. While it certainly resists cam-out, the teeth or splines on the drivers tend to break all too easily--sometimes after driving only 20-30 screws. I dont know whether the problem is with the number of points, which makes each drive spline too thin, or inadequate heat-treating, or what. I do know that if, like me, you use this type of screw in large quantities (I am a builder and specifically a timber-framer), you will need a significant back-up supply of the drivers. That said, I continue to use these screws for their strength, good looks, and durability.

Great quality

Theyre screws... What can I say?

Na

I am building a 32 x 32 retaining wall with landscaping timbers to enclose my childrens playset. Found these screws and took a gamble. It may seem strange to get excited about screws...but these are really amazing. In fact, Im ordering another box of them right now. A strong drill bit comes in the box. Even better, no stripping of the screw is possible since the drill bit rests inside the screw very deeply!
