Traditional wood screws have a blunt thread angle of 60° (displaces material, risk of splitting), have a thicker minor diameter thereby deforms the wood, so pre-drilling is recommended.
Expandet Heco-Topix wood construction screw is suitable for fixing of wood constructions, trusses, stairs, insolation on trusses etc. without pre-drilling.
The special design prevents risk of cracking.
The revolutionary point and shank geometry makes work quick and easy.
Lower installation torque (moment) due to specially designed ribs.
