About this item

  • Size: 1/4 inch X 5 inch
  • Heavy duty wood screw with 6 sided hex bolt head
  • Features deep wood screw threads and does not accept a nut
  • Used in applications where standard wood screws cannot support the load (deck building, etc.)
  • Requires pilot hole to be drilled and installs using wrench or socket tool
  • Thread Type: Deep, Point Style: Gimlet
  • Specification(s) Met: ASME B18.2.1 and ASTM A307A


Lag screw bolts are used in place of standard wood screws whenever the mounting surface must bear a heavy load. The hex head allows for lag screws to be tightened with more torque than can be used on Phillips head screws, though a pilot hole is still required prior to installation. Note that lag screws do not accept nuts as they are technically thick heavy duty wood screws with threads designed to cut into wood. They are ideal for use on decks since installation can be accomplished without having access to both ends of the fastener, as opposed to standard hex bolts that require a nut on the opposite end.

Someone needs to do math - only received 42 of the 50 bolts in the packing. The interior packaging did have a hole in the plastic (not the Amazon shipping envelope .. the plastic bag from the manufacturer), so some were likely removed though the bag prior to it being sent to me.Lag screws did the job. I needed to mount through a 4x4 and had no issues with any snapping (although I did drill a pilot hole for them first) as some have reported.Would have been 5 stars except for the missing ones...

My impact driver broke 11 of the pack of 50. What sort of metal was used in their manufacture? I would have returned them but all others were in use. Not as good as I had hoped.

I've used three of these bolts and two of those broke clean off as I was inserting them (into wood). 2/3 is not a good failure rate.

These lag bolts are great and are $30 cheaper then buying them at Home Depot or Lowe’s! We used a spray paint to achieve the look we were going for! Amazing! Highly recommend!

These lags broke with very little torque even when predrilled while building a tree house for my kids I do not recommend buying these at all
