Application

• For use outside (e.g. carports, playground equipment, pergolas, porches, bridges, bridge plank flooring, balconies)
• Fastening of sheet metal (e.g. solar roof hooks)

Advantages

• Better tightening of connections also of warped boards
• Washer head guarantees higher beam supporting forces and allows savings with regard to piece numbers and working time

Special properties

1. Wide overlying washer head Washer head
2. Stainless steel A2 II: high corrosion protection
3. SPAX 4CUT cutter (For screw lengths of 160 mm and larger): significantly reduces the screwing in torque
4. SPAX T-STAR plus: secure bit grip, no cam-out effect, optimal force transmission

Features

1. SPAX 4CUT point: allows screwing in without pre-drilling (wood-dependent), reduces splitting as square end displaces the fibres
2. 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.
