Ensure your timber constructions are built to last with our professional range of structural timber screws. Engineered for maximum strength and ease of use, these fasteners are the modern alternative to traditional coach bolts. Whether you are securing heavy garden sleepers, building a deck frame, or constructing a pergola, our structural screws provide a flush, secure finish with superior pull-through resistance.

At 414 Fencing, we stock a variety of lengths and head types—including Hex head and Wafer head designs—to suit every landscaping and structural application.
