Spax construction screw, cylinder head, T-Star plus 4-Cut Torx, Wirox

SPAX structural screw with cylindrical head, fully threaded. 
Torx TX drive. 
Carbon steel material with Wirox corrosion protection coating. 
Suitable for timber structures and wood joints. 
T-STAR plus head, the bit tip stays in place better during work.
 

Fast and secure fastening with lower torque, allowing more screws to be driven per battery charge. The wave thread of SPAX screws cuts wood fibers quickly and efficiently. The 4CUT point effectively reduces wood splitting. No pre-drilling required (depending on the wood type).

CE marked, ETA-12/0114 approved.
