Screws ZYP Pozi CSK SCREW TITE

Screw-Tite Woodscrews, Zinc Yellow Passivated Finish Deep cross recess head eliminating slip out of bit or driver. The part thread eradicates "Jacking" where a full thread would tend to pull materials apart. TS Threadform utilises the technology of both Twinthread and Single thread on the same screw. Ribs on the leading edge of the head, ream and self-countersink the screw. Increased collar size strengthens the most vunerable part of the screw whilst allowing for deeper recess. The screw is CPT hardened. This case and through a hardening process allows perfect balance between core ductility and surface strength giving the screw equal qualities to a high tensile bolt, with no requirment for a pilot hole. Tri-lock Threadform shank forms as well as cutting a thread, providing 25% less insertion torque but more importantly; the screw will not work loose over time as the wood flexes under use. Unlike most other performance screws, screw-tite works exceptionally well with most types of Wallplugs as the thread does not have cutting serrations to damage the plug and impede functionality.
