Specification Brand : RAW PRODUCTS CORP BulletPoint1 : Lag bolts feature a hex head and are designed to be driven with a wrench or hex driver. BulletPoint2 : Lag screws are also commonly called lag bolts because they are significantly larger than most other screws. BulletPoint3 : Essentially, it is just a very large wood screw with the threads extending to the top. BulletPoint4 : They feature the sharp cutting threads of a wood screw or sheet metal screw and have a shoulder below the head (in longer lengths), however everything is scaled up in size for use in larger applications. BulletPoint5 : These screws typically need a pre-drilled whole and are not recommended as self-tapping.
