5/16x6 Pwr Cst Construction Structural Screw-10/Pack

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.
