¿Para qué sirve un tornillo barraquero?

Para fijar herrajes metálicos a madera, unir montantes de madera entre sí y montar estructuras de madera. Con un taco de nylon también sirve para fijar en pared.

¿Hace falta taladrar antes?

En madera normal se rosca directamente, porque es autorroscante. En maderas muy duras conviene hacer un pretaladro para que entre mejor.

Technical data by diameter

Manufacturer's values for the galvanised DIN 571 coach screw.

Technical data
Diameter	Spanner size (mm)	Thread inner diameter (mm)	Thread pitch (mm)	Head thickness (mm)	Characteristic tensile (kN)
Ø6	10	4,2	2,6	4,0	7,40
Ø8	13	5,6	3,5	5,5	11,80
Ø10	17	7,0	4,5	7,0	18,90

The characteristic tensile value is the capacity of the screw alone, without safety factor. In very hard woods, over about 550 kg/m³, it's best to pre-drill.

Frequently asked questions about coach screws

What is a coach screw for?

For fixing metal hardware to wood, joining timber posts together and building timber structures. With a nylon wall plug it can also be used to fix to a wall.

Do you need to drill first?

In normal wood it screws straight in, because it's self-tapping. In very hard woods it's best to pre-drill so it goes in more easily.

What spanner do I need?

It depends on the diameter: 10 mm for the Ø6, 13 mm for the Ø8 and 17 mm for the Ø10.

Are they galvanised?

Yes, they're galvanised steel, with protection for indoor or under-roof use.

Do you ship?

Yes. We deliver across Tenerife and ship to the other islands. You can also collect them from our warehouse in Icod de los Vinos.
