The Spax T-STAR Plus T20 Black Galvanised Full Thread Wood Screw in 3.5x20mm is a precision-engineered fastener designed for reliable wood assembly applications, available in a 200-piece pack.
Insert the screw directly into wood using a T20 T-STAR Plus bit. The full thread and 4CUT point allow for clean, efficient driving into softwoods and composite boards. Suitable for furniture assembly, joinery, and general woodworking tasks requiring a secure, flush finish.
Do these screws require pre-drilling? In most softwood applications, the 4CUT point allows direct driving without pre-drilling. For hardwoods or near edges, pre-drilling is recommended to prevent splitting.
What driver bit is needed? These screws require a T20 T-STAR Plus bit, which provides a more secure fit and better torque transfer than a standard Torx T20 bit.
Are these screws suitable for outdoor use? The black galvanised coating provides moderate corrosion resistance, making them suitable for sheltered outdoor or indoor applications. For fully exposed outdoor environments, a higher corrosion-resistance grade is advisable.
What materials can these screws be used with? They are primarily designed for softwood, hardwood, and wood-based panels such as MDF and chipboard.
What is the thread coverage on a full thread screw? A full thread screw has threading running the entire length of the shank, maximising grip and pull-out resistance, particularly useful in thinner materials or end-grain applications.
