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.
Which material should I choose - BZP, A2, or A4 stainless steel?
The coach screws at Fusion Fixings are available in 3 material types which cover a larger range of applications.
• BZP (Bright Zinc Plated): Ideal for indoor use or dry conditions.
• A2 Stainless Steel: Great for outdoor projects such as fences or decking.
• A4 Stainless Steel: Marine-grade corrosion resistance and the best choice for coastal or highly corrosive environments.
Can I use coach screws in brick, block, or concrete?
Coach screws are primarily for timber; however, they can be used in masonry for certain applications if combined with a suitable wall plug or anchor.
