FastenMaster FMHLGM412-250 HeadLOK Heavy-Duty Flathead Fastener, 4-1/2 Inches, 250-Count,Black

I love these. They looked great on my new cedar raised beds and they have a lot more gripping power than a traditional wood screw.

Used to build a deck, these things literally saved the day, Ill continue to purchase these for any large wood project that I have to work on where full support is needed/required (deck footers/stairs/railing). Awesome product at a decent price (fairly expensive, but time saving).

Love these. Very strong.

What more can I say about big screws, they worked.

comes with spider bit, tough structural screws

They worked great.

I absolutely LOVE the HeadLOK fasteners. I have been buying them for the last year or so and have used them for various wood projects. I have stocked up on various sizes including 2-5/8, 4 1/2 and 6 screws. The go right in solid rough oak with no pre-drilling. Oops, made a mistake and have to take one out... no problem... They come right out as easy as they went in and they have a very nice looking flush mount. Right now I am using them for two projects at this moment. Shoring up an old barn and replacing the barn loft floor and building a 150 cow/calf corral, all in solid rough oak. I am getting ready to buy 4 more pales/buckets of the 4 1/2 to complete the corral project. I wouldnt switch or use any other screw for strength and ease of use. They out perform everything I have ever used previously.

These have become a staple around our property! They work great and we have purchased multiple lengths. You do need an impact drill.

Works great, strong.
