Description
The Dynatec 4.0 x 40mm Tec 4 High Performance Woodscrews are precision-engineered fasteners designed for civil engineering contractors and groundworkers who demand speed and dependability on site. These screws are a smart choice when working with hardwood, softwood, chipboard, plywood, MDF, OSB, and oak, delivering consistent results across a range of timber and composite materials.
These screws are ideal for heavy-duty carpentry and joinery in civil engineering projects — from timber formwork and shuttering to securing drainage runs or access covers where durable, reliable fixings are essential. The unique sawfix serrated thread reduces installation torque and speeds up fitting, helping site teams maintain efficiency without compromising on strength or finish quality.
