FAQs about coach screws

What are hex head coach screws used for?

Hex head coach screws are heavy-duty screws designed for securing timber to timber, or timber to metal. The heavy-duty nature of the coach screw sees them commonly used in decking, fencing, roofing, and heavy joinery applications. The hexagonal head allows for higher torque using a spanner or socket for a firm, reliable hold.

How are coach screws different from coach bolts?

A coach screw had a pointed tip more like traditional screws and threads directly into wood without a nut. A coach bolt (also called a carriage bolt) has a flat tip, is used with a pre-drilled hole, and passes through the material being secured on the other side with a nut.

Can I use coach screws outside?

The bright zinc plating (BZP) of these Coach Screws offers a general resistance to corrosion and isn’t suitable for long term external use.

For external use, A2 stainless steel is recommended for long term use, with A4 stainless steel offering a highest level of corrosion resistance, included the use in salt water environments.

Do I need to drill a pilot hole first?

Yes, with the heavy-duty nature of the coach screw, always pre-drill a pilot hole before installation.

Should I use a washer under the head?

It’s good practice to use a flat washer beneath the hex head as this spreads the load across a wider area and protects the timber surface.
