FREQUENTLY ASKED QUESTIONS (FAQ)

What is a coach screw used for?

Coach screws are used for heavy-duty fastenings in timber constructions where high mechanical strength and secure anchoring are required.

What does DIN 571 mean?

DIN 571 is the standard for hexagon head coach screws and defines the screw's geometric design and dimensional properties.

When should one choose A4 instead of A2?

A4 is recommended in marine environments, coastal installations, and other environments with high corrosion stress where acid-proof stainless steel is required.

Is pre-drilling necessary for assembly?

Pre-drilling is recommended in harder wood species and for larger dimensions to reduce the risk of splitting and to facilitate installation.

Which tool is used for assembly?

Installation is performed using a socket or wrench adapted for a hexagon head.
