Product
The Spax T-STAR Plus T20 Black Galvanized Full Thread Wood Screw in 4x50mm is a high-performance fastener designed for reliable wood assembly in construction and joinery applications, available in a 200-piece pack.
Specifications
- Full thread (TF) design along the entire shank for maximum grip and holding power in wood
- Black galvanized coating providing corrosion resistance suitable for interior and protected exterior applications
- T-STAR Plus T20 drive recess engineered to minimize cam-out and deliver precise torque transfer
- 4mm diameter and 50mm length offering a balanced combination of penetration depth and structural integrity
- Compatible with standard T20 Torx-style bits for efficient installation
Usage
Drive the screw directly into wood using a T20 bit without pre-drilling in most softwood applications. The full thread engages the material along its entire length, pulling components tightly together and resisting withdrawal forces effectively in framing, decking, and furniture assembly.
FAQ
- Do these screws require pre-drilling? In most softwood applications, pre-drilling is not necessary. For hardwoods or near board edges, pre-drilling is recommended to prevent splitting.
- What driver bit is required? A T20 T-STAR Plus or standard Torx T20 bit is required for installation.
- Are these screws suitable for outdoor use? The black galvanized coating offers moderate corrosion resistance, making them suitable for protected exterior or interior use, but not for fully exposed outdoor environments.
- What does full thread (TF) mean? Full thread means the threading runs along the entire length of the shank, maximizing grip and pull-out resistance compared to partial thread screws.
- How many screws are included in the pack? Each pack contains 200 screws.
