Spax WIROX Construction Screw

Description

Spax WIROX 6.0 x 100mm x 100 box construction screw

Woodworking

Attachment of counter-battens and wood based panels (e.g. suction-proof fastening of roof battens)

Constructing stairways

Attachment of the treads and risers to the string

Advantages

Considerably reduced screwing-in torque and reduced splitting effect
Length specification and manufacturer logo on the head
Higher head traction forces than countersunk head screws

Approved by building authorities

Under licensing number Z-9.1-235. Z-9.1-511 – approved by building authorities for fastening rooftop insulation systems

Special properties

A = Wide overlying washer head
B = WIROX P3J: The surface with extremely high protection against corrosion
C = SPAX 4CUT cutter (For screw lengths of 160 mm and larger): significantly reduces the screwing in torque
D = Partial thread; firm tightening of the upper wood layer
E = 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 contersunk 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.
