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

Nice finish for my jobs.

Great quality

Started using this type of screw for my deck rail, fencing and landscaping projects. Works great.

We no longer use lag screws for any application, these and the other structural fasteners by FastenMaster and others have made lag screws obsolete. No need to pre-drill in most applications and I have yet to break one or strip out a head. They are also stronger then lag screws that are 50% larger in diameter. I.E. A 1/4 Headlok is stronger then a 3/8 standard lag screw. Forget about these pulling out either, you will have to destroy the wood beam/header/joist before these will pull out.

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.

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

When i saw this nail straighten out a bowed 2x4 into a stud i was seriously impressed. Ive looked all over my house to see where else i could use these they are so much fun to use. Ended up using these to attach a TV mount to a wall.

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

These are hard to find at our local hardware or Home Depot and when I can get them they charge premium price, so this is a great deal for me. I use them for barns, out buildings, fencing and other general projects around the farm. Using the HeadLock fastners ensure that what we build stand up to the abuse of the elements and animals. They pull warped boards together without going in deep like the smaller heads do. These have been the best damn screws we have found.

The best screws. Great quality. V easy to use
