General Construction Structural Screw-5/16" x 4"-50/Pack

The PWR DRIVE CST screw is specifically designed for ledger boards. Crafted from hardened steel, it offers exceptional tensile strength, torque, and shear resistance. Notably, pre-drilling is unnecessary, saving valuable time on the job site. Its sharp threads and type 17 tip minimize wood splitting, while the “U” thread reduces friction on the screw shank, extending battery life for your tools. The CST features a wide flat head with nibs and under-head cutting serrations, ensuring a clean finish when embedded in wood. Plus, the T-40 firm-grip drive provides both torque strength and reliable bit retention, even in challenging positions. What sets the PWR DRIVE CST apart is its certification: it complies with the ICC/ESR-4558 evaluation, meeting the International Building Code (IBC) and International Residential Code (IRC) standards for structural properties and corrosion resistance. For easy job site inspections, all CST screws bear head markings.
