Countersunk Woodscrews are hardened steel screws with a twin thread with a Bright Zinc Plated finish. These are a general purpose screw suitable for multiple materials and various ironmongery, electrical and plumbing applications. Available in sizes 4 x 1/2" up to 12 x 4".
These screws have a Pozi head which when used with the correct tooling will not cam out, allowing greater torque to be applied. A Pozi screw is easily distinguished from the classic Phillips cross-head by extra lines embossed at 45 to the slots providing four additional points of contact for the driver.Please note: standard specification on these twin thread BZP woodscrews, is fully threaded up to and including 1½” lengths. For sizes thereafter, they are part threaded for circa 60% of the total screw length.
