Rated 5.0 out of 5 by 5 reviewers.
Rated 5.0 out of 5.0 by Sharp & Very Strong Pulling Screw! I used these to Fasten the Sill Plate to the top of the wall & Anchor the 2x4 wall sections to 6x8 Oak Timbers for the 16x16 Shed/Work Shop. These are very sharp & will cut easily (Both Wood & Oneself) if not careful. They really do "Zip" right in & can be sunk below surface if so desired. I used a Ryobi +One Impact Driver G4 to do the work & these shine right along with the tool & made it easy. The Spider Drive Bit came with the Screws & I ended up using only 1 bit for over 200 screws & still going. If you need to repair Joists or Rafters buy these & some Liquid Nail Glue & BAM! You Done!

Rated 5.0 out of 5.0 by Excellent heavy duty fastener The headlok fastener gimlet tip is easy to start, threading has excellent grip, is super tough, and the wafer head design is terrific. February 17, 2015
Rated 5.0 out of 5.0 by Perfect for sistering joists Product worked great, and becuase it has the sheer strength as framing nails, I used for attaching a sister joist for structural repair. The grab on these is great and really snugs up the two pieces - once engaged in the wood, my battery powered impact driver put them in like butter...even sunk the head belwo the surface. Much easier than even using a framing nailer - will never use anything else when doing joist repair as it pulls the wood together exceptionally...highly recommend. Also, I bought extra bits, but i put in >50 screws (including the 4.5 inch brother) without stripping. October 23, 2014
Rated 5.0 out of 5.0 by A bit expensive but I love these screws Used for deck construction - smooth coating on screw - drives easily - star bit supplied in box - screws hold great. October 28, 2014
