FastenMaster OMG-FMHLGM278-500, 2-7/8"

3 Driver bits included!

Used to mount a mantle over the fireplace and they worked great. But they are pricey. I suppose if you consider the holding power you can get by with using fewer than you would with std screws or lag bolts, but you know you'll never do that. ;-)

Very good for fastening 5/4 x6” boards to 4x4 posts

Great value

These screws are awesome. They are much stronger than deck screws. They are much faster to install than lag or carriage screws and look even better. The large flat head provides much more holding power without the need for washers and still keeps a low and smooth profile. I used them for wooden railing on my bridge and they look great against the stained wood.When installing any of these spider drive screws you need to apply lots of pressure to keep the bit well engaged especially on the longer screws that take more power. You will wear the tips out and need to use more than one to complete a bucket.

I love these screws for dressing out my stall fronts. They serve two purposes. Look and function. And come with two bits.

These screws are STRONG. I use them to construct holding pens for livestock and have yet to have one fail. They have a lifetime warranty against rust and corrosion, which means your construction project won't develop rust streaks or come apart from rusting away. The spider drive head is a huge improvement over Philips or square-drive type screws, as it's impossible to cam these out when driving them into even the hardest woods. The large head dresses up even the most plainest of projects and gives a very neat, clean appearance.

I used these to attach my band of my new deck in a uniform way. It pulls the wood in tight and looks great instead of the unsightly nail/screw holes. I also used the 5 1/2 to attach my post for my railing. The screws are very durable and the bits are non slip - made for the impact drill. It's a must have for outdoor projects. This is the 3rd time I've used these and will definitely continue.
