The ASSY® 4 HCR 1.4539 CS stainless steel screw is designed for outdoor timber construction and marine environments
Technical Specifications
  • Dimensions (H x L x W): 2.5mm x 50mm x 8mm
  • Weight: 0.003 kg
Key Features
  • Made of high-quality austenitic HCR stainless steel 1.4539 with countersunk head for wood-wood fastening in areas severely exposed to corrosion (corrosion resistance class IV)
  • Ideal power transmission thanks to RW drive
  • More power due to larger contact area at the bit
  • More stability, one-handed working, precise positioning due to the tight-fit recess and perfect fit of the bit
  • Fewer bit changes, one bit for many screw diameters
  • Compatibility with previous AW drive
  • Form-fitting connection to metal fittings or in wooden products with high bulk density
  • Perfect fit of 90° head in fitting parts with metal countersinks
  • Pulls together without head milling due to lack of milling elements below the head
  • Higher breaking torque and power transmission in hardwoods due to reinforced, asymmetrical thread flank geometry
  • Better anchoring thanks to higher thread flanks
  • Smooth thread start ensures optimized recessing and biting of the screw
  • Reduced splitting effect due to displacement effect of dome-shaped milling elements in the tip
  • Friction-reduced thread rotation allows reduction of screw-in force
  • Suitable for high chloride or SO2-contaminated areas with exposure to splash water or fog
  • Non-magnetic and non-rusting stainless steel, class HCR
