Countersunk Delta Seal

Description

Ideal for use on timber structures where a flat countersunk finish is required, the SPAX countersunk head screw is a modern, innovative screw for timber connections.

It is a partial thread screw for clamping timber components together, achieving better performance than traditional batten screws.

Key Features
  • Quick and easy installation compared with traditional wood screws, saving time and money
  • Higher load capacities due to coarse thread design and high strength steel
  • Four-cut point and serrated thread for reduced chance of splitting the timber and reduced screwing-in torque
  • Unique T-STAR plus recess for better torque transfer and reduced chance of stripping the head
  • Multi-head will self-countersink in timber or act as a brake in metal brackets
  • 8, 10 and 12mm diameters available in DELTA-SEAL coating for superior corrosion protection and resistance to timber treatments
  • 6 and 8mm diameters available in stainless steel
Categories
