Frequently Asked Questions

Do I need to pre-drill for Sirius coach screws?

Yes, pre-drilling is recommended, especially in hardwoods or near timber edges. Drill a pilot hole slightly smaller than the screw's core diameter (excluding threads) to prevent splitting whilst maintaining optimal grip. For softwoods, you may use a slightly larger pilot hole for easier installation.

What's the difference between coach screws and coach bolts?

Coach screws thread directly into timber like large wood screws and feature hex heads for spanner installation. Coach bolts pass completely through materials and require a nut on the opposite side. Sirius coach screws are ideal when access to both sides isn't possible or when you need the strength of a lag screw connection.

Can Sirius coach screws be used in treated timber?

Yes, Sirius coach screws are suitable for use with treated timber. However, ensure you select appropriately corrosion-resistant finishes for outdoor applications, particularly with modern pressure-treated timber which can be more corrosive to standard fixings.
