Richelieu FTC17GO5166L PWR DRIVE CST - Structural Screw for General ConstructionRichelieu FTC17GO5166L PWR DRIVE CST - General Construction Structural screw offers a robust solution for your construction needs with its hardened steel composition. This structural screw is engineered to deliver high tensile strength, exceptional torque, and superior shear strength, surpassing that of standard lag screws. One of its standout benefits is the ability to install without pre-drilling, significantly saving time on the job site. The sharp threads and Type 17 point are designed to bite quickly and minimize wood splitting, while the unique "U" thread reduces friction on the screw shank, resulting in less driving torque and extended battery life for your tools. Equipped with an oversized flat head featuring nibs and under-head cutting serrations, the PWR DRIVE CST ensures easy countersinks and a clean finish upon embedding into wood. With a T-40 firm-grip drive, this screw not only provides exceptional torque strength but also stays securely attached to the bit, which is essential for working in tight spaces. The PWR DRIVE CST complies with ICC/ESR-4558 standards, ensuring adherence to the International Building Code (IBC) and the International Residential Code (IRC) for structural integrity and corrosion resistance. Packaged in a box of 50, this screw is ideal for structural assembly in treated lumber and other wood types.
PWR DRIVE CST - General Construction Structural screw
The PWR DRIVE CST screw is made of hardened steel to provide a degree of high tensile strength, high torque, and super shear strength that a regular lag screw just cannot offer. This results in the instant advantage of not having to pre-drill, which is quite a time saver on the job site. The sharp threads and points bite quickly, a type 17 tip reduces wood splitting and a clearing thread, called the "U" thread, reduces the friction on the screw shank, for reduced driving torque and more importantly increased battery life for your tools. The PWR DRIVE CST has a wide flat head with nibs and under-head cutting serrations for easy countersinks and will embed in wood with an incomparable clean finish. This screw also has a T-40 firm-grip drive, that not only provides exceptional torque strength but allows the CST to stick to the bit, which is paramount when you work in less than ideal positions.
It is also worth mentioning that the PWR DRIVE CST is part of the ICC/ESR-4558 evaluation, which certifies CST as fully compliant with the International Building Code (IBC) and the International Residential Code (IRC), for both its structural properties and corrosion resistance. This is why all CST screws have head markings for easy job site inspections
For all these reasons, PWR DRIVE CST screws are a great replacement for lag screws and are the screws of choice for structural 'spec' applications.
