Product
The Spax T-STAR Plus T20 Black Galvanized Full Thread Wood Screw in 4x25mm is a precision-engineered fastener designed for reliable wood assembly, available in a 200-piece pack.
Specifications
- Full thread design (TF) ensures maximum grip and holding power throughout the entire screw length
- Black galvanized coating provides corrosion resistance suitable for interior and protected exterior applications
- T-STAR Plus T20 drive recess reduces cam-out and allows high torque transmission with compatible T20 bits
- 4mm diameter and 25mm length make this screw well-suited for thin to medium wood panels and joinery work
- SPAX patented 4CUT point enables direct driving without pre-drilling in most softwood applications
- Serrated thread geometry reduces splitting and insertion resistance in wood materials
Usage
Insert the screw directly into wood using a T20 Torx-compatible bit. The 4CUT point and full thread allow clean, controlled driving without pre-drilling in softwood. Use for furniture assembly, cladding, paneling, and general carpentry where a secure, flush finish is required.
FAQ
- Do these screws require pre-drilling? In most softwood applications, the SPAX 4CUT point allows direct driving without pre-drilling. For hardwood or near edges, pilot holes are recommended to prevent splitting.
- What driver bit is compatible with these screws? These screws require a T20 T-STAR Plus bit, which is compatible with standard Torx T20 bits, though the T-STAR Plus profile offers improved fit and torque transfer.
- Are these screws suitable for outdoor use? The black galvanized coating offers moderate corrosion resistance. These screws are appropriate for interior use and sheltered exterior applications, but not for fully exposed or high-humidity environments.
- What does full thread (TF) mean? Full thread means the threading runs along the entire length of the screw shaft, maximizing grip and pull-out resistance, particularly useful when joining thinner materials.
- How many screws are included in the pack? Each pack contains 200 screws of size 4x25mm.
