Frequently asked questions about this product

Answered by specialists

Which screwdriver bit is required for this screw?: You need a T20 bit (Torx / T-STAR plus) for optimal bit engagement and superior torque transmission.
Is pre-drilling required in wood?: In softwoods and chipboards, pre-drilling is usually not necessary. Pre-drilling is recommended for hardwoods.
What is the benefit of a full thread?: The full thread provides high pull-out resistance and firm hold across the entire length in sheet materials.
What are the benefits of the WIROX coating?: The WIROX coating delivers significantly higher corrosion protection and surface hardness compared to standard zinc plating.
Does the screw head sit flush with the surface?: Yes, the countersunk multihead self-countersinks cleanly into the wood for a smooth, flush finish.
