Questions & Answers
What is a coach screw used for?
It fastens timber to timber and metal to timber, driven by its hex head and held by the gimlet-pointed thread.
How is it driven?
The hexagonal head is turned with a spanner or socket, allowing higher clamping pressure than a screwdriver.
Is hot dipped galvanised the same as galvanised?
Hot dipping gives a thicker zinc coating than standard galvanising, improving corrosion resistance.
Can I use a washer with it?
Yes, a matching M6 hot dipped galvanised washer can be seated under the head to spread the load.
Is it suitable for outdoor use?
Yes, the hot dipped galvanised finish resists corrosion outdoors.
