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

Was a good option for areas on deck that needed structural support.

They are the best I have ever used. I used them on a deck they also look great.

Built some outdoor benches that are going to take a beating. These are torx head screws (my favorite kind of drive) with an oddball size driver. Luckily a quality driver bit is included in the box. These babies bit down and drove home solidly. The larger than normal heads act as a washer to help keep joints tight. If you have a project that is going to take a lot of racking and stress I recommend these.

great screws that worked as expected

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.

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

My favorite fastener by a country mile. Ive used hundreds to build gardens, playsets, even furnature. So, epically strong. One note, if you pre drill and used a 5/8ths spade bit to carve out 1/8 deep into the pre drill hole, you get a very professional look.

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

I have used these screws when making raised garden beds. They work great, and I found the price here on Amazon cheaper than the local big box stores.
