Ideal for Ledger Boards

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.
