Frequently Asked Questions

Q: What size driver bit do I need for these T25 Torx screws?

A: These screws use a T25 Six-Lobe (Torx) drive, so you'll need a T25 Torx driver bit or screwdriver. This drive style helps prevent cam-out, giving you better torque control when driving into wood or composite materials.

Q: Are these screws suitable for outdoor use like decking and fencing?

A: Yes! The color zinc galvanized plating on these fasteners provides corrosion resistance, making them well-suited for outdoor applications including fence panels, deck boards, and cement board installations exposed to the elements.

Q: Do these screws require pre-drilling?

A: These are self-tapping screws with a coarse thread design, which means they can drive directly into many wood and composite materials without pre-drilling. However, for harder woods or near edges, pre-drilling a pilot hole is recommended to prevent splitting.

Q: How many screws come in each pack?

A: Each pack contains 100 pieces. They are available in multiple sizes: 4.5×35mm, 4.5×45mm, 4.5×60mm, and 5×80mm, so you can select the length best suited to your project.
