Special properties
- Wide overlying washer head
- Delta-seal coating: high corrosion protection
- SPAX 4CUT cutter (For screw lengths of 160 mm and larger): significantly reduces the screwing in torque
- SPAX T-STAR plus: secure bit grip, no cam-out effect, optimal force transmission
Features
- SPAX 4CUT point: allows screwing in without pre-drilling (wood-dependent), reduces splitting as square end displaces the fibres
- SPAX ground serrations: up to the point – quick and secure fastening
Application
The non-threaded part must completely reach through the upper component. The washer head then pulls the upper component tighter to the lower component with each thread rotation.
Advantages of a washer head compared to a countersunk head:
Better tightening of connections. Easy bolting of steel parts and sheet metal to wood.
Washer head allows higher beam supporting forces.
Further advantage:
Also narrow and thin wood cross-sections can be bolted with 6 mm Ø thread.
