Product
The Spax T-STAR Plus T20 Black Galvanized Full Thread Wood Screw in 4x20mm is a precision-engineered fastener designed for reliable wood assembly applications, available in a 200-piece pack.
Specifications
- Manufactured with a black galvanized finish, providing corrosion resistance suitable for interior wood applications
- Full thread design (TF) ensures maximum holding power along the entire shank length
- T-STAR Plus T20 drive recess reduces cam-out and allows precise torque transfer during installation
- 4mm diameter and 20mm length make this screw ideal for lightweight to medium-duty wood connections
- SPAX patented 4CUT point technology enables direct driving without pre-drilling in most softwood applications
- Serrated thread design reduces splitting and improves pull-out resistance in wood substrates
Usage
Drive the screw directly into wood using a T20 Torx bit. The full thread engages the material along its entire length, securing panels, boards, or structural wood elements firmly. The 4CUT point minimizes the need for pre-drilling, streamlining assembly workflows.
FAQ
- Do these screws require pre-drilling? In most softwood applications, the 4CUT point allows direct installation without pre-drilling. For hardwoods or near edges, pre-drilling is recommended to prevent splitting.
- What driver bit is required? A T20 T-STAR Plus Torx bit is required for optimal fit and torque transfer.
- Are these screws suitable for outdoor use? The black galvanized finish offers basic corrosion resistance, making these screws best suited for interior or sheltered applications.
- What does full thread (TF) mean? Full thread means the threading runs along the entire length of the screw shank, maximizing grip and pull-out resistance in the wood.
- How many screws are included in the pack? Each pack contains 200 screws of size 4x20mm.
