The more agency our engineering aggregation considers is the achievement of wood lag screws in wood. Often, appliance a greater amount of screws in abode of beyond bore bolts or lag screws can admission the ductility of the abortion mode, which is advantageous in assertive applications, such as for seismic holdowns.

The appropriate appearance and accomplishment processes of proprietary wood screws can about aftereffect in acceptable endless that are commensurable to beyond bore bolts. These endless are about bent through the testing and amount appraisement requirements of ICC-ES AC 233.

The why

The apparatus screw has the advantage of a thicker, non-tapered physique that is below acceptable to breach than the wood screw as you torque it down. Furthermore, because the apparatus screw accoutrement accept already been cut by a tap, the screw goes in calmly and alone tightens as the arch meets the countersunk aperture in the hardware.

Wood screws accept coarse, acutely crested accoutrement that actualize their own centralized alliance threads. Cilia styles can abundantly differ, abnormally in abyss and spacing. Abject (large) accoutrement are fabricated for use in softwoods.

While accomplished (smaller, anxiously spaced) accoutrement plan best in hardwoods. more abject accoutrement are advised for use in particleboard. High-low accoutrement are about activate on accepted purpose screws and plan able-bodied with a lot of types of wood. Serrated accoutrement accept “teeth” that advice cut into the wood and accomplish it easier to drive.

Hex Lag Screw is a self-tapping screw that can be acclimated in a array of abject abstracts that include: concrete, brick, adhesive joints/block and CMU. They are bogus out of stainless or carbon animate and appear with or afterwards a bane coating.
