About this item

  • Size: 1/2 inch X 4-1/2 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.

They are awesome and you can't beat the price. Use these to mount shelves on my wall in the shop. Needed this link to get through the 2x4 5/8 sheetrock and into the 2x6 stud in the wall. Works great the shelves are hanging
