Product Overview

Our Flat Head Hex Socket Drive Timber Screws are engineered to solve the most common challenges in wood construction — from deck building and fencing to heavy-duty structural timber projects. Featuring precision-designed knurling threads and a Type 17 cut point, these screws eliminate the need for pre-drilling, prevent wood splitting, and deliver a flush, professional finish every time.

Built to withstand harsh outdoor environments, they are available in carbon steel or premium stainless steel (SS304/SS316), with high-performance Ruspert or Dacromet coatings for exceptional corrosion resistance, even in ACQ-treated lumber and humid conditions.
