Fitting and handling
The Torx drive reduces cam-out during installation, which is useful when fixing at pace through hardwoods or dense treated timber. No pre-drilling is required in most softwood applications, but pilot holes are recommended in hardwood or close to timber edges to prevent splitting. Store unused screws in a dry location, as the green coating is corrosion-resistant rather than fully rustproof in prolonged standing water.
FAQ
Are these screws suitable for use with pressure-treated timber?
Yes. The green coating on JG Timberfast 6.3mm structural screws is designed to resist the corrosive chemicals found in modern pressure-treated and tanalised timber, making them a practical choice for outdoor structural work.
What Torx bit size do I need for 6.3mm Timberfast screws?
JG Timberfast 6.3mm screws typically require a T30 Torx bit. Check the specific product packaging to confirm, as drive sizes can vary between batches or product ranges.
Which length should I choose for decking boards?
For standard 32mm or 38mm decking boards fixed to a softwood joist, the 100mm length is a common choice, giving good pull-through resistance without over-penetrating the joist. For thicker boards or where greater structural load is expected, the 125mm or 150mm options provide additional holding strength.
