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

works like a charm

I first used these a couple of years ago when I made a raised light fixture box in our kitchen. I was honestly stunned by the holding power hey have. The oversized head is great, no need for a washer. I still drill pilot holes because I feel it is better for the wood to reduce splitting. I have just started building folding workbenches for my garage using these to mount the brackets to the wall studs. Again drilling pilot holes these screws dig in and pull in hard. I have to be careful not to let them bend the bracket as they go in with such force.

Great fastener, now if theyd just make the drivers a bit more sturdy...

Very manly fastener, I probably spent $1000 on fasteners of various types for my dock and deck. These may seem pricey but Im hoping they last forever. The box states that they outperform 3/8 Lag screws and I believe they would. However, I did not notice that they should not be used within 1000 of saltwater.

love these screws use them in a lot of projects now

This fastener is easy to use and for the most part seemed to do the job. However, I needed 48 fasterners to accomplish my project. When I opened the sealed box I found only 46 fasteners. Frustrated and with time running short, I simply ordered another box of 50 to get the additional two fasterners required. When the second sealed box arrived, I opened it and counted the number of fasteners. Again, I received only 46 fasterners in a box clearly marked 50 screws. Finally, e-mail was sent to FastenMaster for their explanation. Two weeks later ... no answer. My suggestion? Try another brand/syle. They are out there, and from my experience they might even work a little better. If you choose to use this product, be prepared for a possible 8% shortage.

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.

Great product, works extremely well. Will buy again.

Excellent, heavy duty.
