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

Nice finish for my jobs.

...and a retaining wall of pressure treated 6x6 lumber. The result is so solid I know I wont need to redo it in the future.

These are really great fasteners! I used them building a pavilion next to my pool and they worked perfectly! I like the star head, never slips. Just wish they werent so darn expensive!

Glad I saw reviews of these screws on some woodworking websites and decided to buy them. I used them to build a large workbench (connecting 4x4s and 2x4s)...much easier than traditional hex-head lag screws or carriage bolts Ive used in the past. Though they say no pilot hole is needed, I found they are so aggressive when being drilled in, they can/will split wood if installed too close to the edge. Pilot holes eliminated that problem. Other than that situation, they really dont need pilot holes. They wide head eliminates the need to use washers, saving time and money, yet allows them to be driven flush or even countersunk. Would happily use them again.

Building a fence.

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.

Awesome fasteners. So much easier than pre-drilling and driving lag screws. Ive used the related LedgerLOK screw as well.

These screws are GREAT... good quality, nicely painted black, and as the head is flat, it nearly disappears once installed. They come with the Driver bit, so no need to look for one. Very happy, to the point that Im using this in various other projects.

Love these and 20 percent cheaper than Home depot!

Worked great!
