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

Love these. Very strong.

worked like a charm!

Was a bit concerned when I saw the price of these for the quanity compared for what I had been paying at a local large do it yourself store. Pail they came in is nice, good quality screws, will be ordering more only larger quanities next time at this great price.

Although they are a bit Pricey, they are without a doubt the best holding screws Ive ever used and I have used them all. They go in rather easily , draw up tightly and hold like the wood was welded. Great Product!

Perfect fasteners to add a structural LVL beam. Very low profile head so you can Sheetrock over the top of the screw heads !

There where quite a few missing the threads in the bucket. Probably A dozen or more.

Came with three 6 point star bits instead of an 8 point for some reason, had to go buy another set of bits. Worked well for my application other than that.

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.

For the price these are the go to lags. Wish the point was a little sharper but can’t complain for the price.

Easy to use and really convenient
